Introduction.

"Electromagnetic field– is the part of space that

Contains and surrounds bodies that are

in an electrical or magnetic state.

D.K. Maxwell.

Purpose: study of the problem of the influence of electromagnetic radiation on

human organism.

Task : study of information about the influence of electromagnetic radiation on

the human body, warning people about danger and developing

concrete proposals for its reduction.

Relevance : millions of people use household appliances every day

technology, cell phones, which are becoming indispensable

attributes of modern man. It is currently recognized that

electromagnetic field of artificial origin is important

significant environmental factor with a high biological

activity. Electromagnetic fields have a detrimental effect on

human organism. The problem considered in this paper is currently

time is in the center of attention of the scientific community, as in our

country as well as abroad. It is necessary to carry out explanatory work on

preservation of human health under the influence of electromagnetic

fields, develop precautions and promote them.

The human body has its own electromagnetic field, like any organism on earth, thanks to which all the cells of the body work harmoniously. Human electromagnetic radiation is also called the biofield (its visible part is the aura). Do not forget that this field is the main protective shell of our body from any negative influence. Destroying it, the organs and systems of our body become easy prey for any disease-causing factors.

If other sources of radiation, much more powerful than the radiation of our body, begin to act on our electromagnetic field, then chaos begins in the body. This leads to a drastic deterioration in health.

And such sources can be not only household appliances, Cell phones and transport. A large crowd of people, the mood of a person and his attitude towards us, geopathic zones on the planet, have a significant impact on us. magnetic storms etc.

Among scientists, there are still disputes about the dangers of electromagnetic radiation. Some say that it is dangerous, others, on the contrary, do not see any harm. I would like to clarify.

It is not the electromagnetic waves themselves that are dangerous, without which no device could really work, but their information component, which cannot be detected by conventional oscilloscopes.

It has been experimentally established that electromagnetic radiations have a torsion (information) component. According to the studies of specialists from France, Russia, Ukraine and Switzerland, it is precisely torsion fields, and not electromagnetic, are the main factor in the negative impact on human health. Since it is the torsion field that transmits to a person all that negative information, from which headaches, irritations, insomnia, etc. begin.

The influence of electromagnetic radiation on humans.

Weak electromagnetic fields (EMF) with a power of hundredths and even thousandths of a watt of high frequency are dangerous for humans because the intensity of such fields coincides with the intensity of the radiation of the human body during the normal functioning of all systems and organs in his body. As a result of this interaction, a person's own field is distorted, provoking the development of various diseases, mainly in the most weakened parts of the body. The most negative property of electromagnetic signals is that they tend to accumulate over time in the body.In people who, by occupation, use a lot of various office equipment - computers, telephones (including mobile phones) - a decrease in immunity, frequent stress, and increased fatigue were found. And that is not all Negative influence electromagnetic radiation!

Sources of negative radiation:geopathic zones , With sociopathogenic radiation: the influence of people on each other , mobile communications and cell phones , computers and laptops , TV , microwaves (microwave oven) , transport

The problem is that the danger is invisible and intangible, and begins to manifest itself only in the form of various diseases.

The circulatory system, brain, eyes, and immune systems are most susceptible to the influence of electromagnetic fields.

The imperceptible influence of electromagnetic radiation every day and every minute is on our eyes and brain, gastrointestinal tract, blood-forming organs and immune system. Someone will say: "So what?"

The facts cited by scientists from various countries in the study of the influence of electromagnetic radiation on humans:

• Do you already know that15 minutes after starting work on the computer at 9-10 summer child changes in the blood and urine almost coincide with changes in the blooda person with cancer? Similar changes appear in a 16-year-old teenager after half an hour, in an adult - after 2 hours of work at the monitor.
• Does the signal from a portable radiotelephone penetrate the brain by 37.5 mm?
• Most women who worked on computers during pregnancy developed abnormal fetuses and had a miscarriage rate approaching 80%;
• brain cancer in electricians develops13 times more often than in workers of other professions;

Effect of electromagnetic radiation on the nervous system:

The level of electromagnetic radiation, even without causing thermal effects, can affect the most important functional systems of the body. Most experts consider the nervous system to be the most vulnerable of them. The mechanism of action is very simple - it has been established that electromagnetic fields disrupt the permeability of cell membranes for calcium ions. As a result, the nervous system begins to malfunction. In addition, an alternating electromagnetic field induces weak currents in electrolytes, which are the liquid constituents of tissues. The range of deviations caused by these processes is very wide - during the experiments, changes in the EEG of the brain, a slowdown in reaction, memory impairment, depressive manifestations, etc. were recorded.

Effect of EMR on the immune system:

The immune system is also affected. Experimental studies in this direction have shown that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. There is reason to believe that under the influence of EMR, the processes of immunogenesis are disturbed, more often in the direction of their suppression. This process is associated with the emergence of autoimmunity. In accordance with this concept, the basis of all autoimmune conditions is primarily immunodeficiency. The effect of high-intensity EMF on the body's immune system is manifested in a depressing effect on the T-system of cellular immunity.

Effect of EMR on the endocrine system:

The endocrine system is also a target for EMR. Studies have shown that under the action of EMF, as a rule, the pituitary-adrenal system was stimulated, which was accompanied by an increase in the content of adrenaline in the blood, activation of blood coagulation processes.

Conclusion.

The impact of electromagnetic fields on human health is

The biological effects of EMR exposure can manifest themselves in various forms: from minor functional changes to disorders that indicate the development of an obvious pathology. The reason for the biological effect of EMR on the body is the absorption of electromagnetic wave energy by tissues.

In general, the absorption of EMR energy depends on the oscillation frequency and electrical and magnetic properties environment. The shorter the wavelength and the higher the frequency of oscillations, the more energy carries a quantum of electromagnetic radiation. The relationship between energy Y and oscillation frequency f (wavelength λ) is defined as

where c is the speed of electromagnetic waves, m/s (in air c = 3*10 8),

h - Planck's constant, equal to 6.6 * 10 34 W / cm 2.

With equal EMR characteristics, the absorption coefficient in tissues with a high water content is about 60 times higher than in tissues with a low content.

A consequence of the absorption of EMR energy is the thermal effect. Excess heat released in the human body is removed by increasing the load on the thermoregulation mechanism. Starting from a certain limit, the body cannot cope with the removal of heat from individual organs, and their temperature may rise. Exposure to electromagnetic radiation is especially harmful to tissues with an underdeveloped vascular system or insufficient blood circulation (eyes, brain, kidneys, stomach, gallbladder and bladder). Eye exposure can cause clouding of the lens (cataract). In addition to cataracts, exposure to EMR can cause corneal burns.

The thermal effect depends on the intensity of irradiation. The threshold intensities of the thermal effect of EMF on the animal's body decrease with an increase in the frequency of EMF. For example, the threshold energy flux density for the UHF range is 40 µW/cm 2 , and for the microwave range it is 10 µW/cm 2 . EMF with an intensity less than the threshold does not have a thermal effect on the body, but according to a number of theories it has a specific non-thermal effect. Data relating to the non-thermal effects of electromagnetic radiation on humans, on this moment are not complete. This is due to the lack of clear criteria for this impact, accessible to direct instrumental control.

The degree and nature of the impact of EMR on the human body is determined by the frequency of radiation, the duration of exposure, the intensity of the EMF, the size of the irradiated surface, and the individual characteristics of a person.

For long-term exposure to EMI of various frequency ranges at moderate intensity (above MPD) characteristic is the development of functional disorders in the central nervous system with mildly pronounced shifts in endocrine-metabolic processes and blood composition. In this regard, headaches, a decrease or increase in blood pressure, neuropsychiatric disorders, and the rapid development of fatigue may appear. Possible hair loss, brittle nails, weight loss. There are changes in the excitability of the visual, vestibular, olfactory analyzers. On early stage the changes are reversible, with continued exposure to EMR, a persistent decrease in performance occurs.

In emergency situations and extremely high levels of EMP acute disorders occur, accompanied by cardiovascular disorders with fainting, a sharp increase in heart rate and a decrease in blood pressure.

electromagnetic radiation, whose levels do not exceed the MPC, but exceed the background ones, can be considered as a stress factor. Under the influence of such electromagnetic radiation, significant functional changes in the state of the cardiovascular and nervous systems are noted. Subjectively, a person has increased irritability, fatigue, headaches, sleep and memory disorders. In this regard, cell phones and computers, as well as various household radio-electronic and electrical appliances, have recently been of particular concern to specialists in the field of electromagnetic security.

Within the radio wave range, the highest activity of the microwave field has been proven compared to HF and UHF.

Electromagnetic radiation (EMR) accompanies modern man everywhere. Any technique whose action is based on electricity emits waves of energy. Some varieties of such radiation are constantly talked about - these are radiation, ultraviolet and, the danger of which has long been known to everyone. But about the impact of electromagnetic fields on the human body, if it occurs due to a working TV or smartphone, people try not to think about it.

Types of electromagnetic radiation

Before describing the danger of a particular type of radiation, it is necessary to understand what is generally in question. A school physics course tells us that energy propagates in the form of waves. Depending on their frequency and length, there are a large number of types of radiation. So electromagnetic waves are:

1. high frequency radiation. It includes x-rays and gamma rays. They are also known as ionizing radiation.
2. Medium frequency radiation. This is the visible spectrum that humans perceive as light. In the upper and lower frequency scale are ultraviolet and infrared radiation.
3. low frequency radiation. It includes radio and microwaves.

To explain the effect of electromagnetic radiation on the human body, all these types are divided into 2 large categories - ionizing and non-ionizing radiation. The difference between them is quite simple:

• Ionizing radiation affects the atomic structure of matter. Because of this, biological organisms the structure of cells is disturbed, DNA is modified and tumors appear.
• Non-ionizing radiation has long been considered harmless. But recent studies by scientists show that with high power and prolonged exposure, it is no less dangerous to health.

Sources of EMP

Non-ionizing electromagnetic fields and radiation surround a person everywhere. They are emitted by any electronic equipment. In addition, we must not forget about the power lines, through which the most powerful charges of electricity pass. EMP is also emitted by transformers, elevators and other technical devices providing comfortable conditions life.

Thus, it is enough to turn on the TV or talk on the phone so that the sources of electromagnetic radiation begin to affect the body. Even such a seemingly safe thing as an electronic alarm clock can affect health over time.

EMI measuring devices

To determine how strongly this or that source of electromagnetic radiation affects the body, devices for measuring electromagnetic fields are used. The simplest and most widely known is an indicator screwdriver. The LED at its end burns brighter with a powerful radiation source.

There are also professional devices - fluxmeters. Such an electromagnetic radiation detector is able to determine the power of the source and give its numerical characteristics. They can then be written to a computer and processed using various examples measured quantities and frequencies.

For humans, according to the norms of the Russian Federation, an EMR dose of 0.2 μT is considered safe.

More accurate and detailed tables are presented in GOSTs and SanPiNs. You can find formulas in them, thanks to which you can calculate how dangerous an EMP source is and how to measure electromagnetic radiation, depending on the location of the equipment and the size of the room.

If radiation is measured in R / h (the number of roentgens per hour), then EMR is measured in V / m 2 (volts per square meter). The following indicators are considered a safe norm for a person, depending on the frequency of the wave, measured in hertz:

• up to 300 kHz - 25 V / m 2;
• 3 MHz - 15 V / m 2;
• 30 MHz - 10 V / m 2;
• 300 MHz - 3 V / m 2;
• Above 0.3 GHz - 10 μV / cm 2.

It is thanks to the measurements of these indicators that the safety for a person of a particular source of EMR is determined.

How does electromagnetic radiation affect a person?

Considering that many people have been in constant contact with electrical devices since childhood, a natural question arises: is EMP so dangerous? Unlike radiation, it does not lead to radiation sickness and its effect is imperceptible. And is it worth observing the norms of electromagnetic radiation?

Scientists also asked this question back in the 60s of the 20th century. More than 50 years of research have shown that the human electromagnetic field is modified under the influence of other radiations. This leads to the development of the so-called "radio wave disease".

Spurious electromagnetic radiation and pickup disrupt the work of many organ systems. But the most sensitive to their effects are nervous and cardiovascular.

According to the statistics of recent years, about a third of the population is susceptible to radio wave disease. It manifests itself through symptoms familiar to many:

• depression;
• chronic fatigue;
• insomnia;
• headache;
• concentration disorders;
• dizziness.

At the same time, the negative impact of electromagnetic radiation on human health is most dangerous because doctors still cannot diagnose it. After examination and testing, the patient goes home with a diagnosis: “Healthy!”. At the same time, if nothing is done, the disease will develop and pass into the chronic stage.

Each of the organ systems will respond to electromagnetic effects in different ways. The central nervous system is most sensitive to the effects of electromagnetic fields on humans.

EMI impairs signal transmission through the neurons of the brain. As a result, it affects the activity of the organism as a whole.

Also appear over time Negative consequences for the psyche - attention and memory are disturbed, and in the worst cases, problems are transformed into delirium, hallucinations and suicidal tendencies.

The influence of electromagnetic waves on living organisms has a large-scale impact and through circulatory system.

Erythrocytes, platelets and other bodies have their own potentials. Under the influence of electromagnetic radiation on a person, they can stick together. As a result, there is a blockage of blood vessels and the performance of the transport function of the blood worsens.

EMR also reduces the permeability of cell membranes. As a result, all tissues exposed to radiation do not receive the necessary oxygen and nutrients. In addition, the efficiency of hematopoietic functions decreases. The heart, in turn, responds to this problem arrhythmias and decreased myocardial conduction.

The influence of electromagnetic waves on the human body destroys the immune system. Due to the clumping of blood cells, lymphocytes and leukocytes are blocked. Accordingly, the infection simply does not meet with resistance from defense systems. As a result, not only the frequency of colds increases, but also an exacerbation of chronic ailments.

Another consequence of harm from electromagnetic radiation is the disruption of hormone production. Impact on the brain and circulatory system stimulates the pituitary gland, adrenal glands and other glands.

The reproductive system is also sensitive to electromagnetic radiation, the impact on a person can be catastrophic. Given the disruption of hormone production, men's potency decreases. But for women, the consequences are more serious - during the first trimester of pregnancy, a strong dose of radiation can lead to a miscarriage. And if this does not happen, then the perturbation of the electro magnetic field can disrupt the normal process of cell division by damaging DNA. The result is pathological development of children.

The effect of electromagnetic fields on the human body is destructive, which is confirmed by numerous studies.

Considering that modern medicine has practically nothing to oppose to radio wave disease, you must try to protect yourself on your own.

EMP protection

Given the whole possible harm, which brings the influence of the electromagnetic field to living organisms, simple and reliable safety rules have been developed. In enterprises where a person constantly encounters high levels of EMR, special protective screens and equipment are provided for workers.

But at home, the sources of the electromagnetic field cannot be screened like that. At the very least, this will be inconvenient. Therefore, you should understand how to protect yourself in other ways. In total, there are 3 rules that must be observed constantly in order to reduce the impact of the electromagnetic field on human health:

1. Stay as far away from EMP sources as possible. For power lines, 25 meters is enough. And the screen of a monitor or TV is dangerous if it is located closer than 30 cm. It is enough to carry smartphones and tablets not in pockets, but in handbags or purses 3 cm from the body.
2. Reduce contact time with EMP. This means that you do not have to stand for a long time near the working sources of the electromagnetic field. Even if you want to follow the cooking on an electric stove or warm up by the heater.
3. Turn off unused electrical appliances. This will not only reduce the level of electromagnetic radiation, but also help save money on your energy bills.

You can also take a set of preventive measures so that the impact of electromagnetic waves is minimal. For example, having measured the radiation power of various devices with a dosimeter, it is necessary to record the EMF readings. The emitters can then be distributed around the room to reduce the load on individual areas of the area. It is also important to consider that the steel case shields EMP well.

Do not forget that electromagnetic radiation of the radio frequency range from communications equipment constantly affects human fields while these devices are turned on. Therefore, before going to bed and during work, it is better to put them away.

IN last years due to the development of technology, the human body is exposed to a high level of exposure to electromagnetic radiation (EMR), which could not but cause serious concern around the world.

What is the effect on living organisms? Their consequences depend on which category of radiation - ionizing or not - they belong to. The first type has a high energy potential, which acts on the atoms in the cells and leads to a change in their natural state. It can be deadly as it causes cancer and other diseases. Non-ionizing radiation includes electromagnetic radiation in the form of radio waves, microwave radiation and electrical vibrations. Although it cannot change the structure of the atom, its influence can lead to irreversible consequences.

Invisible danger

Publications in scientific literature raised the issue of the adverse effects on individuals and society as a whole of non-ionizing EMF radiation emanating from power, electrical and wireless devices in everyday life, at work, in educational and public institutions. Despite numerous problems in establishing compelling scientific evidence for harm and gaps in elucidating the exact mechanisms of harm, epidemiological analysis is increasingly suggesting the significant potential for traumatic effects produced by non-ionizing radiation. Protection against electromagnetic radiation is becoming more and more important.

Due to medical education does not focus on the state of the environment, some physicians are not fully aware of the likely health problems that are associated with EMR, and as a result, manifestations of non-ionizing radiation may be misdiagnosed and treated ineffectively.

If the possibility of damage to tissues and cells associated with exposure to X-rays is beyond doubt, then the impact of electromagnetic radiation on living organisms, when they come from power lines, mobile phones, electrical appliances and some machines, has only recently begun to attract attention as a potential threat. health.

electromagnetic spectrum

Refers to a type of energy that emanates or radiates far beyond its source. The energy of electromagnetic radiation exists in various forms ah, each of which has different physical properties. They can be measured and expressed in terms of frequency or wavelength. Some waves have a high frequency, others have a medium frequency, and still others have a low frequency. The electromagnetic radiation range includes many different forms of energy coming from various sources. Their name is used to classify EMP types.

The short wavelength of electromagnetic radiation, corresponding to a high frequency, is a characteristic of gamma rays, x-rays, and ultraviolet radiation. More spectrum include microwave radiation and radio waves. Light radiation belongs to the middle part of the EMR spectrum, it provides normal vision and is the light that we perceive. Infrared energy is responsible for human perception of heat.

Most forms of energy, such as x-rays, ultraviolet and radio waves, are invisible and imperceptible to humans. Their detection requires the measurement of electromagnetic radiation using special instruments, and as a result, people cannot assess the degree of exposure to energy fields in these ranges.

Despite the lack of perception, the action of high-frequency energy, including X-rays, called ionizing radiation, is potentially dangerous for human cells. By altering the atomic composition of cellular structures, breaking chemical bonds, and inducing the formation of free radicals, sufficient exposure to ionizing radiation can damage genetic code in DNA or provoke mutations, thereby increasing the risk of malignant neoplasms or cell death.

Anthropogenic EMR

The influence of electromagnetic radiation on the body, especially non-ionizing, which is called forms of energy with lower frequencies, has been underestimated by many scientists. It was not considered to produce adverse effects at normal exposure levels. IN Lately, however, there is increasing evidence that some frequencies of non-ionizing radiation have the potential to cause biological harm. Most of the studies on their impact on health have dealt with the following three main types of anthropogenic EMR:

• the lower scale of electromagnetic radiation from power lines, electrical appliances and electronic equipment;
• microwave and radio emissions from wireless communications devices such as cell phones, cell towers, antennas, and television and radio towers;
• electrical pollution due to the operation of certain types of equipment (for example, plasma TVs, some energy-saving appliances, variable speed motors, etc.) that produce signals whose electromagnetic frequency is in the range of 3-150 kHz (propagated and re-radiated by wiring).

Ground currents, sometimes called stray currents, are not limited by wires. Current follows the path of least resistance and can pass through any available path, including ground, wires, and various objects. Accordingly, electrical voltage is also transmitted through the ground and through building structures through metal water or sewer pipes, as a result of which non-ionizing radiation enters the immediate environment.

EMR and human health

While studies examining the negative properties of electromagnetic radiation have sometimes yielded conflicting results, the diagnosis of reproductive dysfunction and cancer predisposition seems to confirm suspicions that EMF exposure may pose a threat to human health. Poor pregnancy outcomes, including miscarriages, stillbirths, preterm births, sex ratio changes, and congenital anomalies, have all been linked to maternal exposure to EMR.

A large prospective study published in the journal Epidemiology, for example, reports peak EMR exposure in 1,063 pregnant women in the San Francisco area. The participants in the experiment wore magnetic field detectors, and the scientists found a significant increase in fetal mortality as the level of maximum EMF exposure increased.

EMR and cancer

Claims that intense exposure to certain frequencies of EMR can be carcinogenic have been examined. For example, the International Journal of Cancer recently published an important case-control study on the relationship between childhood leukemia and magnetic fields in Japan. By assessing the level of electromagnetic radiation in the bedrooms, scientists have confirmed that high levels exposures lead to a significantly greater risk of developing childhood leukemia.

Physical and psychological impact

People with electromagnetic hypersensitivity often suffer from exhaustion, which can affect any part of the body, including the central nervous system, musculoskeletal system, gastrointestinal tract, and endocrine system. These symptoms often lead to permanent psychological stress and fear of being exposed to EMP. Many patients become incapacitated just thinking that an invisible wireless signal at any time and in any place can provoke painful sensations in their body. Constant fear and preoccupation with health problems affect well-being up to the development of a phobia and fear of electricity, which in some people make them want to leave civilization.

Mobile phones and telecommunications

Cell phones transmit and receive signals using EMF, which is partially absorbed by their users. Since these sources of electromagnetic radiation are usually in close proximity to the head, this feature has led to concerns about the possible adverse effects of their use on human health.

One of the problems in extrapolating the results of their application in experimental studies in rodents is that the frequency of maximum absorption of RF energy depends on the size of the body, its shape, orientation and position.

Resonance absorption in rats is in the range of microwave and operating frequencies of mobile phones used in experiments (from 0.5 to 3 GHz), but on the scale of the human body it occurs at 100 MHz. This factor can be taken into account when calculating the absorbed dose rate, but is a problem for those studies that use only the external field strength to determine the level of exposure.

The relative depth of penetration in laboratory animals is larger compared to the size of the human head, and tissue parameters and the mechanism of heat redistribution differ. Another potential source of inaccuracies in exposure levels is the exposure of the cell to RF radiation.

The effect of high-voltage radiation on people and the environment

Power lines with voltages above 100 kV are the most powerful sources of electromagnetic radiation. Studies of the radiation impact on technical personnel started with the start of construction of the first 220-kV transmission lines, when cases of deterioration in the health of workers appeared. The commissioning of 400 kV power lines led to the publication of numerous works in this area, which later became the basis for the adoption of the first regulations limiting the effect of a 50-Hz electric field.

Power lines with a voltage of more than 500 kV have an impact on the environment in the form of:

• electric field with a frequency of 50 Hz;
• radiation;
• magnetic field of industrial frequency.

EMF and the nervous system

The mammalian blood-brain barrier is composed of endothelial cells associated with barrier zones as well as adjacent pericytes and extracellular matrix. Helps maintain a highly stable extracellular environment necessary for accurate synaptic transmission and protects neural tissue from damage. Increasing its low permeability to hydrophilic and charged molecules can be detrimental to health.

The ambient temperature exceeding the limits of thermoregulation in mammals increases the permeability of the blood-brain barrier for macromolecules. Neuronal absorption of albumin in different areas of the brain depends on its temperature and manifests itself when it rises by 1 °C or more. Since sufficiently strong radio frequency fields can lead to tissue heating, it is logical to assume that the effect of electromagnetic radiation on a person results in an increased permeability of the blood-brain barrier.

EMF and sleep

The upper scale of electromagnetic radiation has some effect on sleep. This topic has become relevant for several reasons. Among other symptoms, complaints of sleep disturbances have been mentioned in anecdotal reports of people who believe they are being affected by EMR. This has led to speculation that electromagnetic fields could interfere with normal sleep patterns, with consequent health consequences. The potential risk of sleep disturbance should be considered given that it is a very complex biological process controlled by the central nervous system. And although the exact neurobiological mechanisms have not yet been established, the regular alternation of states of wakefulness and rest is necessary requirement to ensure the proper functioning of the brain, metabolic homeostasis and the immune system.

In addition, sleep seems to be exactly that physiological system, the study of which will make it possible to find out the effect of high-frequency electromagnetic radiation on a person, since in this biological state the body is sensitive to external stimuli. There is evidence that weak EMFs, much lower than those at which a rise in temperature would occur, can also cause biological effects.

Currently, studies on the effects of non-ionizing high-frequency EMR are clearly focused on cancer risk, due to concerns about the carcinogenic properties of ionizing radiation.

Negative manifestations

Thus, the impact on a person of electromagnetic radiation, even non-ionizing, takes place, especially in the case of high-voltage power lines and the corona effect. Microwave radiation affects the nervous, cardiovascular, immune and reproductive systems, including causing damage nervous system, changing its response, electroencephalogram, blood-brain barrier, provoking a disturbance (wakefulness - sleep) by interfering with the pineal gland and creating hormonal imbalances, changes in heart rate and blood pressure, worsening immunity to pathogens, causing weakness, exhaustion, growth problems, DNA damage and cancer.

It is recommended to erect buildings away from EMP sources, and protection from electromagnetic radiation of high-voltage power lines should be mandatory. In cities, cables must be laid underground, as well as equipment that neutralizes the effect of EMP.

According to the results of a correlation analysis based on experimental data, it was concluded that it is possible to significantly reduce the impact of electromagnetic radiation of power lines on a person by reducing the distance of wire sag, which will lead to an increase in the distance between the conductive line and the measurement point. In addition, this distance is influenced by the terrain under the power transmission line.

Precautionary measures

Electricity is an integral part of life modern society. This means that EMP will always be around us. And in order for EMF to make our lives easier, not shorter, some precautions should be taken:

• Children should not be allowed to play near power lines, transformers, satellite transmitters or microwave sources.
• Locations where the density exceeds 1 mG should be avoided. It is necessary to measure the EMF level of devices in the switched off and operating state.
• It is necessary to carry out a rearrangement in the office or at home in such a way that it is not exposed to the field of electrical appliances and computers.
• Don't sit too close in front of the computer. Monitors vary greatly in the strength of their EMP. Do not stand near a working microwave oven.
• Move electrical appliances at least 2 m from the bed. Do not allow wiring under the bed. Remove dimmers and 3-position switches.
• Be careful when using wireless devices such as electric toothbrushes, shavers.
• In addition, it is recommended to wear as little jewelry as possible and take it off at night.
• It is also necessary to remember that EMP passes through walls, and to take into account sources in the next room or outside the walls of the room.

On the human body (abbreviated as EMP, electromagnetic field - EMF) has been studied by specialists since the invention of electricity: large research institutes conducted research on children, pregnant women and even not whole generations of people.

As a result, according to the official data of the WHO (World Health Organization), EMR is recognized as dangerous if exposed for too long.

Radiation sources These are mobile electronics, telephone towers, transformers and many other electronic devices. It is impossible to protect yourself from electromagnetic radiation. It is contained in a natural amount in the natural field of the earth. For example, the result of EMP in the atmosphere is flashes of ions during the northern lights.

But if the influence of electromagnetic radiation on a person is negative, how to maintain one's health and compensate for unpleasant ailments?

Sources of electromagnetic radiation

The more electronics are produced, the more EMP sources humanity receives. You can not demand to stop the process of technologization: the scientific and technological revolution has led to the rise of electronics.

Now it occupies an important place in human life. Some electrical appliances even support the lives of hospital patients on mechanical ventilation or in a coma, and in these cases, the effect of EMR is negligible.

If radiation sources are to be avoided, the only way out is to simply not buy certain items or go near the following range of influencing things:

• Cell phones;
• tablets;
• LCD TVs;
• energy-saving lamps;
• transformer boxes;
• large electrical cables;
• sockets;
• refrigerators;
• domestic electrical generators;
• devices for tomography of the brain;
• and much more.

The effect on the human body is the stronger, the longer he uses the device. To limit the action, it is enough to move away from the equipment by a few meters.

Results of various studies

In the USSR, Spain, the USA, Great Britain and other countries, studies were conducted on the subject of the effect of EMR on children and adults. Here are the main facts about radiating devices that were revealed during the experiments.

How does radiation affect the embryo?

Pregnant women who constantly worked at the PC during the period of bearing a child were more prone to miscarriages.

80% had prerequisites for its appearance and even full-fledged cases.

The other study group, who didn't spend as much time around electronics, had a much lower miscarriage rate. The study was conducted in the United States in the early 2000s. Now Computer techologies stepped forward, and the waves became less dangerous for humans.

Children who talked on the phone for 20 minutes then showed changes in brain activity for 2 hours. A group of 11-13 years old was taken for testing. The experiment was set up in Britain in the 90s.

The same experts, but later tested the impact of computers on children and adults. Children about 10 years old showed blood and EEG changes similar to those of cancer patients after only half an hour. Teenagers - in an hour, and adults - in 2 hours. The changes faded away within the same amount of time.

Experts from the University of Bristol have proven that the reaction rate in children aged 11-14 who constantly use the phone decreases by 1.5-2 times. Similar results were revealed by Finnish studies that studied the effects of electromagnetic fields and radiation on the human body.

In the USSR, experiments were carried out on animals. The offspring of those individuals that were even slightly irradiated during pregnancy turned out to be less viable. It showed anomalies not only in development, but also at the genetic level.

Based on the above data, EMR does indeed have an effect on living organisms, including humans.

How exactly does the process of exposure take place, which organs are affected by electromagnetic waves?

The nature of changes under the influence of EMR

Electromagnetic waves - these are some vibrations that transmit energy from induction electrical systems and affect living organisms and inanimate objects.

Induction or irradiation occurs when electrons move unevenly inside a closed space. Electrons are also part of the human body, as a result of which a microscopic magnetic and electronic field arises around a person.

Electromagnetic radiation affects a person by changing his natural field. Some life functions depend on the field. For example, own electromagnetic radiation affects the reaction rate of neurons, brain activity, reaction.

With an external influence that leads to violations of the natural levels of the waves, the functions go astray. As a result, the body begins to get sick, showing various EMR-related dysfunctions.

What does radiation affect?

The waves emitted by electrical appliances and natural sources affect most of the departments of the human body:

• reproductive system;
• cardiovascular system;
• endocrine organs;
• departments responsible for immunity;
• nervous system;
• brain.

Each department in its own way suffers from constant doses of radiation. And although waves are less dangerous than radiation is commonly believed, the problem of EMP is more relevant: wave induction surrounds us at every step, and therefore is more dangerous.

Effect of EMR on the brain

Studies by prestigious British and American institutes of science, Finnish organizations and Russian research institutes have shown that EMR reduces the activity of the nervous system.

Signals from the brain to the periphery and vice versa are transmitted more slowly. Part of the information is lost along the way, resulting in failures: convulsions, absent-mindedness, incorrect mechanical movements.

Decreases, especially in children, the reaction rate. This leads to an increased risk of death due to accidents, the suppression of a sports career. Waves have a negative effect on brain activity, temporarily exerting a kind of "stupefying" effect on a person.

Side effects for the reproductive system

With the constant impact of induction on the reproductive system, the reproductive function decreases. A person either becomes completely infertile, or partially loses the viability of germ cells.

Male gametes - spermatozoa - stick together, which makes it more difficult to conceive a child. In women, the menstrual cycle is interrupted.

People with "electric" professions (repair of transformer booths, electrician, IT specialist) often have children with developmental anomalies.

Depression of the cardiovascular system

Vessels, especially in the eye area, after a long stay in front of radiating devices are significantly narrowed. The outflow and inflow of blood slows down, the brain and other organs suffer from oxygen starvation.

Due to their malnutrition, vision deteriorates sharply, the heart begins to “play pranks”. People who are prone to heart attacks are at greater risk of their occurrence when working with PCs and mobile devices.

Changes in the endocrine system

The thyroid gland has recently been showing dysfunction mainly in adolescents. This is caused not only by natural causes (their rapid growth and hormonal changes), but also by the influence electronic devices.

With constant exposure to EMR, the risk of developing iodine deficiency, excess thyroxine production, and delayed physical development increases.

Regular computer users show increased rates of ankle swelling, even if the breaks and exercises necessary to compensate for them were taken during work. It is also associated with hormonal disruptions.

Conclusion on the effect of radiation on humans

It cannot be unequivocally said that one should abandon all electronic devices at once and go to healthy lifestyle life. It is impossible to refuse their use. Easier to comply simple recommendations, which will reduce the negative effect of electronics.

Children should use phones and computers as little as possible, about 30-60 minutes a day. Adults should be limited to 2 hours. When working with electronics, you need constant breaks.
