Electromagnetic radiation phone mode in flight. Electromagnetic radiation of a mobile phone: truth and myths

A lot has been said about the harmful radiation of mobile communications. Today, almost every owner of a mobile phone knows that during the establishment of a radio connection between the operator's base station and a mobile phone, the latter emits electromagnetic pulses. high frequency. It is still impossible to answer unequivocally whether it is harmful or not. More than 15,000 doctors of various specialties from 12 countries of the world participated in the research devoted to the study of the effect of electromagnetic radiation on the human body.

These studies did not bring any definite results. Doctors found no obvious and direct manifestations of harm from a mobile phone. But they did not dare to firmly declare total absence harmful influences. After all, unpredictable consequences can manifest themselves much later, and even affect future children. It is not easy to distinguish truth from scientific fiction, because interests are tied to any research in this area. mobile operators, equipment manufacturers and officials.

In the meantime, in anticipation of objective research, we - users can only minimize the impact of electromagnetic radiation on our own body. That is why we decided to compare the radiation of household devices that surround us in order to figure out which devices are relatively safe and which ones should be kept away from.

How did we test?

The measurements were carried out using an Aktacom ATT-2592 electromagnetic field analyzer. This is a portable instrument designed for safe measurement of electromagnetic background characteristics that can be performed at home. The device is recommended for use to measure radiation generated by wireless communications (CDMA, DECT, GSM, Wi-Fi), as well as household appliances.

The main parameters that interest us are the electric field strength (20 mV / m - 108 V / m) and the energy flux density (0 μW / m² - 30.93 W / m²). Of course, it is difficult, if not impossible, to achieve absolutely accurate indicators at home. But there was no such goal. The main task is to determine how different devices and technologies are in terms of the level of radio emission.

The measurements were carried out in the most ordinary apartment of one of the new buildings in the central district of the capital with basic set household appliances: refrigerator, TV, washing machine, electric kettle, and laptop.

In general, the device behaved quite clearly, and in most cases there was no doubt about the performance. With repeated measurements, the values ​​deviated slightly, which indicates a small level of error.

We traditionally paid attention to mobile phones first. One often hears arguments: “Today there is so much technology in our homes that there is more telephone, less telephone - it does not play a significant role.” In fact, if we admit that electromagnetic radiation is still dangerous, then the telephone will be the source of maximum danger. After all, we do not put a microwave oven or a TV on our heads for a long time. That is why these devices may well radiate much stronger than mobile phones, but already at a distance of a meter, the radiation is scattered. In the case of telephones, the radiation not only affects the brain directly during a conversation, but also irradiates the user when the device is in standby mode, in close proximity to the body - for example, in a pocket.

That is why we measured the radiation of mobile phones several times - in standby mode (the phone is on the table), in talk mode, and also in dial mode, when theoretically the device emits the most radiation. For a more accurate selection, we took two mobile phones of the most common GSM standard - Nokia 6300 and Nokia 6303, as well as two CDMA phones: the old Nokia 6225 and the popular Nokia 1508.

The value ranged from 3 mW/m² to 800 mW/m 2 . At the same time, peak values ​​were reached at the time of dialing and establishing a connection. During these few seconds, holding the phone close to the head is not recommended. I was surprised by the difference in performance of phones of different standards. So, if the values ​​for a GSM phone were in the range of 40 mW / m 2 - 800 mW / m 2, then for a CDMA device the same indicator was 3 mW / m 2 - 150 mW / m 2. If a home wired telephone were available, perhaps the figures would be even lower. This shows that in phones of different standards, the radiation level can differ by dozens of times.

In the case of other household appliances, the distribution of indicators was more or less even. We observed a change in indicators in different models of refrigerators and electric kettles, however, the fluctuations are not so significant, and the radiation range itself allows the use of devices at a distance, thus minimizing the impact.

Operating range of household electrical appliances

In this case with household appliances radiation power is not as important as the radius of impact. After all, no one will get rid of refrigerators, vacuum cleaners and microwave ovens, but it is quite possible to move appliances to a safe distance. During testing, we were able to approximately determine such a “safe” distance at which the device no longer detects any radiation.

— Hood. The device picked up radiation within a radius of 30 cm. However, in different devices this distance may vary. The thickness and materials of the body of the device, as well as its power, play a role.

— electric stove. In most metropolitan new buildings, gas is not supplied to apartments, and gas stoves are not installed. They are being replaced by safer electric stoves. According to our measurements, electromagnetic radiation from such tiles spreads within a radius of 30 cm, so you should not stay at such a distance for a long time.

— Refrigerator. We measured the radiation from two completely different models refrigerators. In the first case, the radius was 30 cm, in the second - almost 80 cm. This means that the dining table should not be placed in close proximity to the refrigerator.

— Electric kettle. Oddly enough, even this apparently quite safe device radiates. And although the range was only 30 centimeters, we do not recommend boiling water in a kettle right on the table while eating.

— TV set. We had an ordinary CRT TV at our disposal, the radiation of which was approximately 1.5 meters. We do not recommend watching TV at closer distances. It is believed that the effect of flat LCDs and plasma panels below, but we still do not recommend approaching.

- Notebook. The radiation of a small 12-inch laptop turned out to be low and was fixed at a distance of 30-40 cm. This means that, if the required distance is observed, working with such devices is relatively safe.

How to protect yourself?

Of course, it is impossible to completely and unconditionally refuse to use any electrical appliances in a modern city. If only because you will inevitably be exposed to radiation while in public transport, in the office, and even just on the street, passing under high-voltage power lines. But the impact can and should be limited. To do this, it is enough to remember the series simple rules and stick to them as much as possible.

1. The more powerful the appliance, the stronger its radiation. Therefore, try to limit the purchase and use of powerful electrical appliances.
2. Avoid placing electrical appliances in the bedroom or in areas where people are often present. For example, an air conditioner located directly above the sofa, where the whole family gathers in the evenings, is not the best solution.
3. Choose mobile phones that operate in the most secure standards. At home, if possible, use a city connection or the CDMA standard.
4. If you are using a cell phone signal booster or remote antenna to boost the signal, make sure that the device is approved for home use and install it strictly in accordance with the instructions.
5. When making a call, try not to hold the phone in close proximity to your head while the connection is established (a few seconds from dialing the number until you hear the ringing tone). During this period, the radiation of the phone is most active.
6. If possible, do not use extension cords to connect powerful electrical appliances. If this is not possible, then make sure that the wires are not tangled.

The debate over how harmful communication using mobile phones is to a person began several decades ago, from the very moment these portable devices began to be in demand first in individual countries, and then throughout the world. Scientists and physicians around the world have been conducting thousands of experiments and studies for many years in order to prove or disprove certain widespread versions about the impact of mobile phones on human life and health. Let's look at the most popular of them, so that in the future each reader can answer the question, did he feel the harm of mobile phones or is it just a myth?

Influence of electromagnetic waves on human health. Scientists have long proven that they are able to stimulate changes at the cellular level and cause violations of the gene order, as well as contribute to the appearance of diseased cells in the body and even pathogenic tumors. So how harmful is the influence of mobile devices, the operation of which is a source of constantly generated electromagnetic waves?

A number of experts who have studied this issue have come to the conclusion that mobile devices can negatively affect health only with excessive, almost round-the-clock use. modern devices or when using outdated, very first mobile phones, which “radiated” much more electromagnetic waves due to the imperfection of technology at the dawn of the era wireless communication. Thus, you can safely communicate using modern models of mobile phones, but do not abuse such communication. The manufacturers of such devices themselves do not believe that the products they produce are more dangerous than those without which not a single house can do in our time.

Negative effect on the immune system. With constant unlimited use, the harm of mobile phones becomes especially noticeable. Studies show that participants in ongoing experiments in Denmark and Norway who used mobile phones daily for a long time, began to complain of drowsiness, headaches and became more irritable than the subjects who limited their communication with cellular communication.

Scientists have also found that the constant use of mobile phones can significantly weaken the immune system, which will lead to a number of diseases and can exacerbate chronic diseases. Therefore, the harm and benefit of cellular communication is the totality of the reasonable use of such brainchildren of progress.

Effect of electromagnetic waves on the brain. Many scientists primarily associate the harm of mobile phones with the influence of electromagnetic radiation on the head. Moreover, such radiation is created around itself not only by mobile phones, but also by a number of other devices that have confidently entered our lives - computers, televisions, microwaves, radiotelephones and other devices.

This affects not only the brain tissues, but also the tissues of the retina, the structures of the visual, auditory and minimizing the harm of mobile phones to “our heads”, again, will allow limiting the use of these devices in everyday life.

Cell phone and children. Due to the fact that the child's skull is thinner and less massive, electromagnetic radiation has a much greater effect on our children than on adults. Therefore, the harm of mobile phones to the children's body is much more noticeable than the impact on the health of adults. Because of this, scientists around the world are calling for the most careful monitoring of the time that children spend talking on their mobile phones.

Thus, we can safely say that the harm and benefits of a mobile phone in modern world are relative concepts. Everything will depend solely on the intensity of use. of this type devices - with a reasonable approach, a mobile phone can bring its owner only benefits, almost completely eliminating the negative impact on the body.

04/11/2019: Six useful tips.And examples from life in the comments, about salivary gland cancer and not only.

Mobile phone radiation has an impact on health.
But the tube will not cause harm if you follow the elementary rules for the safety of its use.
And they are quite simple, and if you follow these tips, the harm from microwave radiation from a cell phone will be minimized.
And the hypotheses of some researchers that smartphones can cause cancerous tumors and Alzheimer's disease will no longer cause panic fear and a desire to immediately get rid of the annoyingly “beeping” device in your pocket.

To minimize the risk possible harmful effects of radiation waves from a working cell phone, you should, if possible:

1 – Limit time and frequency phone use. Still, you need to remember that a smartphone is not a stationary secure phone on which you could talk for hours. More 2-3 minutes per call and more than 10-15 minutes a day you should not talk on a mobile phone.

2 - Try your best do not use the phone in areas where reception is poor(elevator, underground premises, transport, etc.), because with poor reception, the mobile phone tries to find the transmitter antenna, and because of this, its radiation (the properties and effects of which on humans have not yet been fully studied ) is multiplied.

By the way, the same applies to countryside, where, far from the antennas, poor mobile reception is also often observed.

3 – less frequently used mobile phone indoors(car, house), since the waves emitted by it can be reflected by walls and coatings, which increases the exposure several times.

4 - Keep in mind that Bluetooth wireless data transmission adds to the mobile phone additional radiation power. Therefore, use a wired headset.

5 – Don't apply smartphone to ear while he is in the process of searching for a network operator(this happens when the phone is turned on and with very poor reception). At this moment, he radiates the most, harms, so to speak, to the maximum.

6 - And finally, rid yourself of the addiction of sleeping next to cell phone, and even more so - put the included, working (and, therefore, constantly emitting!) mobile phone under the pillow! Be sure to turn it off before going to bed or unplug its transmitter!

Also, if you are used to using your mobile phone as an alarm clock, you can postpone him away from you. This will not only greatly reduce the risk of phone exposure during undisturbed sleep, but also greatly increase the likelihood of your successful awakening. After all, in order to turn off the alarm clock, you will definitely have to get out of bed.

This article is a collection of ways to protect against the harmful effects of a cell phone from various sources of information. You don't have to try to follow all the tips. The degree of application of advice depends on the degree of your desire to protect yourself. If you try to use at least a few tips from this article, then you will already help yourself.

"Voluntary irradiation of the brain with microwaves from a mobile phone is the largest biological experiment on a person."

Professor Leif Salford.

At present, almost the entire population, scientists, doctors, physicists are very concerned about this problem - the impact of a mobile phone on the human body. This is due to the fact that, firstly, the number of cellular users is growing exponentially daily and hourly, and secondly, the number of base stations is growing, and they are also a direct source of radiation. And, finally, the proximity of the phone to the head and the recorded increase in cases of brain tumors also make us wary and link the phone and the deterioration of human health together.

Some may object: "To live is generally harmful, people die from it, whatever you take - everything in our life is destructive (faster or slower)!" Maybe, but as they say, he who is warned is armed. It is better to know what leads to what and what consequences await in the future. And then it’s up to everyone personally to listen to advice or leave everything as it is, especially since a person does not immediately become adult and smart, usually this is preceded by a stage of childhood, and a child is not only possible, but also needs to be protected from all kinds of influences, at least for his prosperous future.

(Techniques, in descending order of effect)

* Call outside.

When the weather permits, it is better to go out for a walk while talking - the phone is mobile.

The walls of the room delay radio waves in the range of 1-2 GHz quite strongly, reducing the signal power by 10-20 dB, i.e. 10-100 times. Due to the peculiarities of communication standards, not all of the extra power may become available when the phone is taken outside, nevertheless, the advantage is obvious.

If you can’t go outside, then at least turn around so that your head does not block the view of the phone through the window to the street - this should give an additional 5 dB.

* Keep the handset away from your ear.

The attenuation of radio waves is proportional to the square of the distance travelled.

Suppose the distance from the antenna of a tube tightly pressed to the ear to the cerebral cortex is 1 cm. Then, moving the tube away from the ear by only 1 cm, you will double the distance to the brain (2 cm), and the power radiated to the brain will decrease by 4 times!

* Hold the phone in your hand by the bottom part.

At the top of the device is an antenna, which, when covered with a hand, loses its effectiveness by 5-10 dB, forcing the phone's transmitter to increase its power by at least 3 times.

This is especially true for phones with an internal antenna (people say "no antenna"). Internal antenna- this is the same external antenna, lowered a couple of centimeters deep into the body. Beautiful and leaves less room for grip (double vulnerability from robbers).

* Hold the handset vertically.

Radio waves, even as short as 1800 MHz (half-wavelength 8 cm) are polarized, so it is desirable that the transmitting and receiving antennas be oriented in the same way (traditionally and for other reasons - vertically).

Experience shows that when simple change orientation of the GSM handset from vertical to horizontal, the level of the signal received from the BS is reduced by an average of 5 dB (3 times).

* Switch your phone to the 1800 MHz band.

GSM standard provides different levels of maximum power for manual equipment: 1 W for 1800 and 1900, 2 W for 900 and 850.

Typically, range selection is automatic and transparent to the subscriber.

Blocking the lower 900 MHz band reduces RF exposure by half.

Do not forget to only turn on the dual-band machine when leaving the city, otherwise you can easily be left without a connection.

* Bring the phone to your ear after the other end answers.

Why listen to the long beeps of the checkpoint, what's new?

In addition, at the moment the call is started, the mobile phone operates at its maximum capacity, regardless of the quality of coverage in a given location.

20 seconds after pressing the "Call" button - just in time for the beginning of the conversation - the radiated power is reduced to the minimum allowable level.

Also note: the first long beep only appears around the 10th second, so listen to the call if you like, but it's pointless to immediately put the phone to your head after dialing.

And yet, do not flatter yourself - in large cities with a dense cellular network, the phone may frequently switch between base stations during a call (sometimes up to 10 times per minute!). With each such switch, the power jumps to a maximum and then slowly drops.

*Choose a phone with a lower SAR (Specific Absorption Rate).

SAR can differ by 2-3 times for different phone models (as a rule, from 0.3 to 0.9 W/kg) - accordingly, the effect on the user's body also differs proportionally.

1. Do not use cell phones for children and adolescents under 16 years of age.

2. Do not use cell phones for pregnant women, starting from the moment the fact of pregnancy is established and during the entire period of pregnancy.

3. Do not use a cell phone for persons suffering from neurological diseases, including neurasthenia, psychopathy, neurosis, the clinic of which is characterized by asthenic, obsessive, hysterical disorders, as well as a decrease in mental and physical performance, memory loss, sleep disorders, epilepsy and epileptic syndrome, epileptic predisposition.

4. When using a cell phone, take measures to limit the impact of the electromagnetic field, namely, to limit the duration of conversations (the duration of a single conversation is up to 3 minutes), to maximize the period between two conversations (the minimum recommended is 15 minutes), to mainly use cell phones with headsets and "hands free" systems.

In fact, today there are several really working methods for protecting the natural electromagnetic field of a person from the pathogenic effects of EMR of artificial and geopathogenic origin:

1. eliminate any electromagnetic fields of technogenic origin according to the principle of fiber-optic communication;

2. reduce the intensity of electromagnetic radiation to values ​​below the threshold;

3. to screen the human body, i.e. to remove it from the band of technogenic radiation;

4. reduce the natural level of human sensitivity to man-made EMR;

5. to carry out the process of adaptation of the human body to the existing level of electromagnetic radiation by increasing the body's natural defense systems, which neutralize the radiation by modifying the body's own biofield status.

To date, the international market has different kinds similar devices. All of them can be divided into several categories:

1. Absorbent materials (synthetic films, wax, felt, paper, etc.).

2. Reflective materials (metal foil on synthetic insulating bases).

3. Protective clothing (from technological fabrics with the inclusion of metallized threads).

4. Conductor devices with antenna properties (bracelets, belts, necklaces, key rings, etc.).

5. Different types of diffraction gratings.

6. Deflecting devices (metal products without coatings and in insulators).

7. Different types of resonators (spirals, cones, pyramids).

For the most part, these devices are passive re-emitters, or modulators of the existing impact. It must also be said that any measures aimed at strengthening one's own biofield and strengthening the immune system, no less contribute to increasing the body's resistance to the negative radiation of electromagnetic devices.

When using the device speakerphone or headphones, the radiation dose is reduced. True, in the latter case, the radiation will be concentrated in the place where in this moment mobile phone is located. Moreover, regardless of whether a person uses a phone or not, when the phone establishes contact with the base station (and this happens several times a day), radiation is still present, albeit small. If the phone just lies next to the user, then there is practically no need to talk about exposure.

Unfortunately, in recent years, with the increase in terrorism against children, the means of cellular communication between parents and children have become necessary, and often vital. At the same time, gradually and as if by chance, the mobile phone has replaced toys for children. Both children and teenagers invariably ask for a mobile phone for their birthday, New Year, September 1, the end of the year with fives. With regard to limiting the use of a mobile phone by children, some operators offer services that allow you to limit the time of a child's calls, the number of subscribers. In addition, especially for children, phones are put on sale from which you can’t call anyone except mom and dad.

What does the modern industry offer to protect against the harmful effects of a mobile phone? The protection of the human body from the harmful effects of EMF is based on the creation of devices that change a weak external electromagnetic signal in the form of a vector directed towards the damaging signal, so this signal is abruptly attenuated. With the introduction of powerful attenuation near a living organism in the form of a protective device that responds to certain frequencies of an external signal (electrically conductive applicators of strictly defined sizes are used for this), the electromagnetic component of the signal is significantly reduced, and, consequently, the equipotential fields and the level of their influence on the body are redistributed. This is the basis for the creation of application protective devices. Manufacturers are currently offering different types protective devices:

1. absorbent materials (synthetic films, wax, felt, paper, etc.);

2. reflective materials (metal foil on insulating substrates made of synthetic materials);

3. protective clothing (fabrics with the inclusion of metal threads);

4. conductors of various shapes with antenna properties (bracelets, belts, necklaces, key rings, etc.);

5. diffraction gratings different types;

6. deflecting devices (metal products without coatings and in insulators);

7. various resonators (spirals, cones, pyramids);

8. generators of electromagnetic pulses.

Among the protective devices currently offered are the following:

1. Wave Guard - a device designed to replace and protect against adverse electromagnetic radiation. Made from Wave Guard absorbent ceramic and highly conductive, high temperature treated materials. This product has been tested by the National Institute of Technology and certified by the Japanese Ministry of Science and Technology. Wave Guard is used in antennas to protect mobile phone users from direct electromagnetic radiation.

2. Development of a bioenergy device - an energy map that completely neutralizes the harmful effects of electromagnetic waves and converts it into positive energy for the body. According to the manufacturers, the energy card not only protects against harmful electromagnetic radiation while using a mobile phone, but also nourishes the brain and the body as a whole with bioenergy: it restores clarity of thinking, stops headaches, normalizes intracranial pressure - waves of ultra-fine fields of the energy card completely restore the human biosystem. The energy card is inserted under the battery of the mobile phone with the front side to the keyboard. The action of the device begins immediately from the moment you bring the telephone to your ear.

3. The use of traditional protective filters (give a slight positive effect).

4. Since during operation, the electromagnetic device creates around itself very difficult arranged field, then a three-dimensional device is needed to protect against this field. This can be achieved by installing several local devices on the source body. When these devices are placed close to each other in a certain order, they are able to begin to interact with each other, creating a kind of spiral network that does not allow the rays of the source of negative radiation to pass. Negative radiations, getting into such a network, change their orientation, obeying certain laws of physics. Joint radiation takes the form of a ball, which ultimately gives a reorientation of the total form of radiation emanating from a specific source of radiation (radio telephone). With certain settings of this protective network, changes are possible, in which case a harmonizing effect that is positive for the human body can be obtained. Thus, the localization and neutralization of negative radiation takes place. According to this principle of radiation of thin physical fields, protection for computers (Super Armor) works. The protection kit includes nine neutralizer devices. Each of the devices is a multi-level display matrix, which is a collection of thin fields. Devices are located according to a special scheme. The scheme was selected experimentally and provides maximum localization of the negative impact of computers and protection of users. Another advantage of this protection system is that it can be placed on a monitor screen with a diagonal of any size, regardless of geometric dimensions. Currently, similar protective devices have been developed for mobile phones. Neutralization devices are multilevel, i.e., in addition to neutralizing the negative electromagnetic component, they are able to significantly weaken the fields of psi-impact. Practical use of these protective equipment, according to their creators, allows you to create a comfortable, harmonious and safe working environment. These funds ("Russian Shield") lead to a decrease in the level of ultraviolet radiation by 100%; electromagnetic field - by 99.4% and electrostatic field - by 99.1%. Calculations of the absorbed energy of the electromagnetic field in the human brain show that when using a radiotelephone with a power of 0.6 W with an operating frequency of 900 MHz, the specific energy of the field in the brain can be from 120 to 230 μW / cm2 (and the standard in Russia for cell phone users is 100 µW/cm2). Improving radiotelephones, as well as providing users with clear, constructive information about the best use of this intercom will certainly reduce the harmful effects of EMF, psi-fields on the user's body mobile communication.

5. The use of "Mini Hands Free" kits (reradiating antenna) reduces head exposure and redistributes it to the whole body.

6. Devices of the "Astra" series ("supertablets").

7. Electromagnetic field protection device "FORPOST-1". The operation of the device is based on the laws of interaction of torsion fields. Said device contains generators of static torsion fields and a biopolymer. The protective action of the device is based on the 180° deviation of the left torsion field, which is generated by a mobile phone or monitor personal computer, and the interaction of this field with the right torsion field of the rear wall of the monitor or mobile phone, which leads to the compensation of these fields. Negative air ions remain in the operator's breathing zone, which disappear from it after 1.5 hours if the monitor or mobile phone is operated without this protective device. The use of a protective device, according to the manufacturers, provides medical and biological protection of a person and prevents the negative impact of the above-mentioned torsion fields on the immune, endocrine, reproductive systems and the genetic apparatus of disorders of the nervous and cardiovascular systems, impaired brain activity, pathology of the visual analyzer, upper respiratory tract, prevents fatigue when working on a computer and using a mobile phone for a long time.

So, here are some practical tips on how to avoid the effects of cell phone exposure.

Firstly, in order to avoid the constant influence of the electric field of a mobile phone, which can have a negative impact on the functioning of your body, you should either completely eliminate or reduce long-term communication on a mobile phone. Even if 1 minute of your conversation costs 1 penny, say as little as possible at a time. For all kinds of medical examinations will have to pay much more. The period between conversations should be at least 15 minutes, and the duration of the conversation itself should not exceed 2 - 3 minutes. It seems that during this time it is quite possible to report necessary information. Some mobile operators have put a special limiter on the conversation. If it lasts more than half an hour, the connection is automatically terminated. The mobile companies that introduced this limiter were guided by purely mercantile considerations, but additionally help to maintain the health of the nation.

Secondly, as we have already found out, in a car, electromagnetic radiation can be reflected from a metal case and acts several times stronger, since it accumulates in the cabin. Therefore, you should not conduct intensive negotiations while driving a car. Moreover, by doing so, you endanger the lives of other people.

Thirdly, if you are in a zone of unstable reception, then you should not try to get through this very second. Wait for a stable connection. When the phone "does not catch", its power rises to the maximum value, and what is dangerous, we found out earlier. In addition, communication interference and all sorts of crackling instead of a normal conversation will not bring pleasure to either you or your interlocutor.

Fourthly, if you are in the country or in a country house, then the best way out is to use a stationary external circular (for example, car) or directional antenna. Outside the city, the connection is poor, so the mobile phone works at its full capacity, trying to contact the base station.

A couple more tips. If you live near the base station or on the top floor next to the located antennas, then if possible it is better to move either to the lower floors or away from the area base station. Moreover, it is better to live in a panel house, because the supporting metal structures of the panels are able to somewhat block and screen the apartment. The antenna radiates such a powerful signal in all directions that its radiation is enough for everyone.

Tips for limiting mobile phone EMF exposure:

1. do not put mobile phones near the place where you usually sleep;

2. do not talk on it without special need;

3. do not use a cell phone for persons who are predisposed to the occurrence of various mental illnesses, as well as for persons suffering from sleep disorders, decreased mental and physical activity and activity;

4. refrain from using the mobile device for pregnant women;

6. do not wear long time a cell phone on the chest, waist or in the breast (or inside) pocket;

7. use models of radiotelephones with a smaller value of UPM;

8. when talking on a radiotelephone, it is recommended to remove glasses with a metal frame, since the presence of such a frame can lead to an increase in the intensity of the electromagnetic field affecting some parts of the user's head;

9. constantly use the "hands free" system;

10. make sure that the distance from the radiotelephone to the surrounding people is not less than 50 - 80cm;

11. in conditions of unstable reception, the power of the device automatically increases to the maximum value, therefore it is recommended to either limit or completely abandon long-term negotiations, or use a place for negotiations with favorable (stable) reception;

12. in the country or in a country house it is more expedient to use a stationary external antenna with a circular orientation (for example, a car) or a special directional antenna;

13. Repeaters of providers also pose a certain danger. The repeater antenna regularly emits a very strong signal in all directions. The best way avoid exposure to EMF repeaters - change of place of residence or work, or change of house to a panel one. The fact is that the panel reinforcement shields the apartment somewhat. Helps to protect against the harmful effects of EMF metal mesh on windows with a cell size of not more than 10 cm;

14. do not damage the telephone antenna, as a change (violation of the structure) of its geometric parameters (dimensions, bends, torsion, etc.) worsens communication (changes reception conditions, increases transmitter power);

15. when purchasing a new phone model, opt for mobile phones equipped with an external antenna, as well as a good sensitivity declared in the specifications;

16. adhere to a balanced diet, lead a healthy lifestyle.

The use of shungite for protection against electromagnetic fields

Today, many people know about the existence of shungite, but 10 years ago this mineral was known only to narrow specialists in the construction industry and was used only as a gravel mixture. In the course of one of the studies, which confirmed the unusual chemical composition of shungite, assumptions were made about its healing properties. Subsequently, clinical trials confirmed the effectiveness of shungite in some disorders. For us, at the moment, the most interesting is the property of shungite to neutralize the negative effects of electromagnetic radiation. Interestingly, even the discovery of the healing properties of this nondescript ash-black mineral did not lead to any changes in its use. So he remained a building material, except that from the category of gravel and crushed stone he moved into the category of all kinds of additives to cement mixtures and paints. It was only by chance that shungite fell into the sphere of interests of those people who rediscovered its properties for the rest.

Now few people know something about the real properties and origin of shungite. Modern scientists believe that shungite (as a geological rock) was formed about 2 billion years ago. One of the common misconceptions is that shungite is a type of coal. In fact, these two minerals are similar only in appearance, but shungite occurs in deeper layers of the earth's crust, the age of formation of which is much older.

The origin of this mineral remains largely a mystery. It is hard to imagine how a rock rich in carbon compounds could have formed at a time when there were no forests and rich vegetation on the planet. At the moment, there are several theories that more or less likely explain the origin of shungite. The most likely version is that shungite was formed from sedimentary marine rocks, which, in turn, were formed from marine sediments saturated with dead microscopic organisms. Some researchers argue that the shape and structure of shungite rocks have features and characteristics of volcanic substances. Thus, there are some grounds for assuming the volcanic origin of this mineral. There is also a more exotic hypothesis of the origin of shungite. According to this version, shungite is part of a huge meteorite, which was a piece of the decayed planet Phaeton, on which life once existed. A shungite deposit was formed at the place where the giant fragment fell. One way or another, but today there is only one known deposit of shungite - in Karelia, and there is no analogue to it yet. The mineral has no equal in its healing qualities and variety of properties.

One of the most interesting qualities of shungite is the ability to eliminate the negative effects of electromagnetic radiation. Before giving a description of the healing properties of shungite, you should get a little familiar with the history of this mineral. At the end of the XVI century. in a deaf monastery on the shores of Lake Onega, a nun of noble birth, Marfa, known to the world as the noblewoman Xenia Ivanovna Romanova, was seriously ill. Due to her health and the severity of her illness, she was soon to die, it would not have saved even the fact that after the death of Boris Godunov, the royal disgrace was removed from the Romanov family. Yes, only the local peasants liked the kind-hearted nun, and they told her that in these places there is a life-giving spring, which is known for its miraculous healing power. Later, her son - Mikhail Fedorovich Romanov - became the founder of the ruling dynasty, which was in power for 300 years, and the healing spring received the name "Princess Key" in memory of the nun. By the name of the key and the surrounding villages began to be called Small and Big Tsaritsyno. Despite their amazing properties, those springs never became widely known, and only local peasants used their power. And no one has ever associated the properties of the Onega springs with the fact that a strange rock lies in those places - the "slate stone", currently known under the name "shungite" (after the nearby village of Shunga).

The rebirth of healing springs (and in fact their new discovery) occurred almost 100 years later, during the Petrovsky transformations and the construction of mining plants and factories in the Urals and northern lands. Fame came to the sources after the accidental healing of a simple factory worker, who thus got rid of "heart disease". This strange incident was told to Peter I, who ordered to examine the water of the source, and then even tried it on himself. Convinced of its medicinal properties, the emperor ordered to organize the first resort in Russia "Marcial Waters". The name of the resort was given by the name of the god of war - Mars, since, first of all, crippled and weak warriors were treated by the waters of the spring by order of Peter. And besides, the "slate stone", which was worn in backpacks, began to be included in the marching equipment of Peter's soldiers in order to disinfect water during campaigns and give it spring freshness. For some time, the source of medicinal waters developed rapidly and became very popular, but, like many of Peter's plans, it was abandoned after the death of the founder. Several centuries had to pass for the healing water and the strange black stone to be remembered again.

The properties of shungite still continue to pose various riddles to scientists. Now only one thing is clear: shungite makes water healing. Moreover, its healing properties are not selective, that is, the mineral neutralizes everything that negatively affects a person, and concentrates and restores everything that is useful. As already mentioned, a unique deposit of shungite has been found only in Karelia. It is also important that this mineral is currently the only one whose composition includes fullerenes (this is a recently discovered form of the existence of carbon in the form of spherical ions). Coming into contact with water, shungite begins to release fullerene complexes, which combine with water molecules. As a result, mineral water is formed, which has pronounced medicinal properties. Shungite waters are now being tried to treat allergies, skin diseases, wounds, burns, diabetes, stomatitis, periodontal disease, hair loss, and cosmetic defects. Shungite can not only have a positive effect on ordinary water, but in itself has no less pronounced properties. For example, a study of the effect of shungite on electromagnetic fields convincingly proved that it is a very effective protection against the negative influence of electromagnetic fields of cell phones, TVs, monitors and the so-called geopathic zones.

Today, there are several options for using shungite: shungite filters for water, shungite additives in building materials (paints, cement, etc.), the use of shungite to create protective screens to neutralize EMF. Approximately in 1991, for the first time, it was proposed to produce filter devices for water purification from shungite. The result of the test was very impressive. The use of water purified by shungite had a healing effect on the course of such diseases as chronic gastritis, stomach ulcers, kidney stones, periodontal disease, and various allergies. So far, the medicinal effect of shungite has not been fully explained. Shungite proved to be no less effective as a filler for filtration disinfecting devices for cleaning wastewater and car washes. Most often, a shungite filter is made from natural minerals: shungite and zeolite. It is they who purify the water and endow it with healing properties. Shungite compounds have pronounced bactericidal properties, which helps to purify water from E. coli and many organic pollutants. The second filter component (zeolite) adsorbs inorganic contaminants very well. Water passed through such a shungite-zeolite filter contains 9-12 times less microbes than water purified using other filters. Not so long ago, studies conducted by the US Environmental Safety Commission helped to find out that it is extremely dangerous to combine water disinfection by chlorination with the use of activated carbon as a sorbent filter filler. That being said, our tap water is still chlorinated and most of our filters are carbon. Under such conditions, all carbon filters release activated carbon dust into the water, as a result of which, when boiled, a toxic compound is formed - dioxin, which not only negatively affects the person himself, but when accumulated can cause genetic disorders. It is believed that a few molecules of dioxin are enough to cause the development of a cancerous tumor. Thus, for filtering chlorinated water, it is better to use shungite filters, which do not interact with bleach and toxic substances and not only do not emit, but also bind all kinds of foreign impurities with the help of fullerenes.

Another extremely important property of shungite is the combination of electrical conductivity and protection against magnetic fields. Our industry is already using shungite with might and main as an additive to various building materials, which makes it possible to screen electromagnetic radiation of high and ultrahigh frequencies during construction. Such materials are used most often in individual construction, for premises that require the protection of confidential information. In addition to additives, shungite plates themselves are also used to decorate the walls of the room, which not only helps to shield the room from all types of magnetic fields, but also simply improves the well-being of a person staying there for a long time. For example, rooms painted with shungite paint have found an interesting use for lovers of strong drinks. It turned out that when a hangover syndrome occurs, a half-hour stay in a room trimmed with shungite is enough for all the negative consequences of immoderate libations to pass without a trace. Special shungite-based additives are now being tried to be added to plastic housings for household and computer technology. This will reduce the negative impact on humans of electromagnetic radiation.

The so-called macrolite plates for cell phones and computer monitors are made from shungite. Small plates cut from shungite are now sold in mobile phone stores. They are attached directly to the base of the phone's antenna, which is how they achieve a reduction in scattered electromagnetic radiation, that is, the quality of the directional signal does not deteriorate, but the "side" rays are successfully extinguished. Such a plate is inexpensive, but its effectiveness has already been fully proven.

Modern society uses a mobile phone every day. Therefore, telecom operators install repeaters. This is necessary to achieve high-quality and uniform EMF.

But few people ask the question - is the radiation of a mobile phone dangerous?

Scientists, professors, doctors warn the whole world about the dangers of the mobile phone. This is due to its function of generating electromagnetic rays.

For several years, no one took seriously the threat posed by mobile phones. But every year specialists accumulated enough information about the irreversible impact of phone radiation on the human body.

More than twenty years ago, British citizens began to turn to doctors with complaints of pain in the region of the heart, which appeared from a mobile located in a chest pocket.

It was then that the head of the National Committee announced the harmful effects of telephone EMF on the human body. This prompted scientists from all over the world to pay attention to this problem and find a way to protect themselves and their children from radiation.

Is a cell phone harmful?

Microwaves are used to communicate with mobile devices, which have a frequency of 300 MHz to 3 GHz. Unlike any other technology, the cell phone is close to the head at the time of the conversation. Therefore, it is capable of causing more harm than a laptop or any other household appliances.

Radiation, even in a small dose from a cell phone, is absorbed by brain tissues, the retina of the eyes, as well as auditory structures. The longer a person talks, the more the tissues will heat up from exposure to electromagnetic waves.

Over time, such exposure will adversely affect the correct operation of not only internal organs but the entire system of the human body.

Complex bioelectrical processes constantly occur in the brain, when electromagnetic radiation disrupts this function, the body begins to fail, a person becomes ill.

The highest radiation power of the mobile phone is noted while receiving or making a call.

Electromagnetic waves can cause irreversible harm to the child's body. They cause constant pain in the head, cause memory disorder, insomnia, as well as nervousness.

SAR characteristic

In the countries of the European Union, a special value for radio emission has been developed, which is called SAR.

It is equal to the amount of radiation received by the human body per kilogram of its weight. The norm for a person is 2 W / kg. Rospotrebnadzor has established that any apparatus should not irradiate a person with more than 100 μW / cm 2.

At the moment when mobile device establishes a connection, this indicator will have the highest value, which is so dangerous for people.

Now manufacturers of cellular devices must indicate in the operating instructions how dangerous and harmful such a device can be, because it is capable of exerting not only a thermal effect, but also a vortex effect.

Russian scientists conducted studies where they managed to find out that any apparatus exceeds the normal values ​​several times. At the time of the conversation, the human brain is subjected to severe overheating. In most cases, this contributes to the onset of brain cancer.

Impact on the children's body

Oxford University professor Lap Blakemouth insists on minimal use cell phones by young children and teenagers. This is due to the fact that at the time of brain growth in a child, the base of the skull is much thinner than in an adult.

Such thin walls cannot resist electromagnetic flow.

Scientists from Britain concluded that children under nine years of age should not use a mobile phone, as they reduce the risk of neoplasms in the auricle, in the brain.

Where to wear a cell phone

Most people wonder where is the safest place to carry a mobile phone?

Experts say that the device, while waiting, produces insignificant harmful electromagnetic radiation, which does not harm a person.

Therefore, the phone can be carried in any convenient place. It can be a pocket of a jacket, jeans or pants, a bag or a hiking backpack.

Radiation protection

A large number of specialists from all over the world are studying every day what effect a mobile phone has on the human body. They not only confirm the harm of radiation, but also offer special protection measures against harmful effects.

Some precautions must be observed, namely:

1. give preference to these devices with a reduced SAR;
2. monitor signal performance;
3. reduce the time of the conversation;
4. do not cover the antenna with your palm;
5. turn off the phone where there is no connection;
6. call next to the window;
7. do not put a mobile phone next to you before going to bed;
8. use headphones and a specialized headset for talking on the phone;
9. while using the phone to access the global network, you must put it on the table;
10. purchase a case for the device and carry it in a bag;
11. communicate via SMS.

In order to protect yourself, experts recommend monitoring the intake level indicator. When the device shows two bars, the reception level is the most favorable, you can talk without fear.

It is also necessary to hold the tube strictly vertically, holding the bottom. When the number of bands decreases, you need to go to the window to improve the reception quality.

The amount of radiation decreases in the following order: call function, access to the global network, SMS communication, phone settings, standby mode.

Experts insist on using the phone no more than 30 minutes a day, when it is better for children under the age of 18 to refuse to use this device altogether.

A mobile phone is best carried in a bag, and it is also necessary to reduce the duration of calls by 3-4 minutes. When doctors allow you to use no more than one hour a day.

The tube should be kept as far away from the ear and head as possible. This will help reduce the dose of radiation. When the phone is pressed to the ear, the radiation exposure will increase four times. For long conversations, doctors recommend using the loudspeaker function.

In order to prevent pregnant women from getting exposure, experts recommend using the phone for no more than half an hour a day and not turning it into the main means of communication and communication.

Who is not allowed to use a cell phone

These devices should not be used by people who suffer from neurological diseases such as neurasthenia, neurosis, psychopathy.

Disorders with asthenic, obsessive and hysterical symptoms. It is also impossible for people with mental retardation and impaired physical performance, with poor memory, restless sleep, epileptics and sick people with an epileptic predisposition.

Experts prohibit the use of a mobile phone by sick people who have a pacemaker installed.

This device aims to stimulate the heart with electrical impulses. Scientists have found that radiation from a mobile phone can cause a malfunction or completely disable the device for the heart muscle.

Diseases caused by exposure to electromagnetic fields on the human body

Scientists from Germany have proved that a mobile phone during work can increase a person's blood pressure. Experts noted that a conversation for half an hour contributed to an increase in pressure from five to ten mm Hg. This is due to the contraction of the vessels of the head, through which blood was supplied to the right hemisphere of the brain.

A Swedish researcher from the Institute of Labor noted that more than 90% of people during a conversation on a mobile phone feel the skin heating behind the ear.

In several cases, mild burns were recorded. Such heating caused memory lapses in people, fatigue, drowsiness, and an increase in body temperature up to 39 degrees.

The Swedish specialist noted that a large number concentration of people decreased, which in most cases led to injuries and accidents.

Specialists from Israel were able to prove to the whole world whether radiation is harmful. Long conversations can cause oral cancer. The appearance of this disease in most cases depends on the duration and frequency of using a mobile phone.

Doctors have proven that a person who has had long conversations for five years is 50% prone to developing mouth cancer.

An Italian scientist proved that phone radiation excites the cerebral cortex, causing an epileptic stroke. People with rapid excitability of brain cells are susceptible to this.

This device has a negative effect on vision. After this radiation, blood flow to the eyes is disturbed. Because of this, the lens is poorly washed with blood, which leads to its clouding and destruction. At this moment, a person feels a noise, a sharp pain in the eyes.

It has been proven that during a long focusing of the gaze on the phone screen, the eye muscles experience a strong overstrain.

Conclusion

In order to prevent the radiating force on the human body, it is necessary to reduce the duration of the conversation or completely stop using the mobile phone. Between conversations there should be a gap of 15 minutes, and the conversation itself can last no more than two or three minutes.

Now mobile operators put a limit on the conversation. This feature helps people not only save their money, but also save their health.

You should not negotiate in a car, as the cure can be reflected from metal objects and accumulate inside the cabin. And also a conversation while driving a car can lead to a serious accident.

If the signal reception level is not constant, you should not call the person, but it is better to wait a bit or find a place where this device will work well. Moreover, interference, crackling during a conversation will not bring pleasure to the interlocutors.

When traveling to a country house or country house, you should give preference to ordinary landline phones. So you can protect yourself from the negative effects of electromagnetic fields.
