What harm can cause electromagnetic radiation. The effect of electromagnetic radiation on the human body

Electromagnetic radiation is the natural habitat of all life on our planet: electromagnetic waves emit outer space above us, the sun's rays, lightning strikes, household appliances and even living things. Moreover, if there were no electromagnetic field of the Earth, there would be no life itself. Unfortunately, electromagnetic pulses can be both beneficial and harmful. It should be understood that the human body is an excellent source of receiving electromagnetic radiation, which means that a long stay in the zone of its strong impact simply cannot pass without a trace for us. Let's see what the effect of electromagnetic radiation on the human body is, and how to protect yourself from it.

Electromagnetic radiation and its sources

This type of radiation arises as a result of oscillations of particles of magnetic and electric fields. As a result, waves with high penetrating power are formed. Depending on the type of emitter, the frequency spectrum and field strength can vary significantly. To date, there is the following classification of types of electromagnetic radiation:

visible radiation or light - these are the shortest waves. Moreover, some animals and insects are able to see much more types of radiation, since their eyes are more sensitive than human ones;
infrared radiation - This type of radiation is not perceived by the human eye. The most famous sources of waves of this type are the sun and large industrial devices;
radio waves - Radio waves are considered the longest. They come from microwave ovens and many other household appliances;
UV radiation - ultraviolet radiation also applies to electromagnetic waves. Sources of UV radiation are sunlight, tanning lamps, stars, laser systems. It is believed that it is UV waves that are the natural source of radiation, capable of exerting maximum influence on humans;
x-ray waves - This type of radiation is actively used in medicine, allowing doctors to take pictures of bones or internal organs. These waves have a wide range of length and high penetration;
gamma radiation- the shortest, but at the same time the most dangerous radiation. Sources of gamma waves can be both natural and artificial sources. They are able to penetrate into any objects and pass through them. In addition, prolonged exposure to gamma rays can cause irreversible changes in the body and even mutations.

It is worth noting that the earth's magnetic field also belongs to the strongest emitters of electromagnetic waves. However, in this case, the effect of electromagnetic radiation does not have a critical effect on the human body. Over thousands of years of life, mankind has taken a huge step forward, learning to create complex technical devices and understanding the power of many natural phenomena. Unfortunately, some of the creations of man, in addition to benefit, carries a potential danger in the form of electromagnetic radiation. The most famous and common sources of electromagnetic waves include:

high voltage power lines;
mobile communication stations;
television and radio towers;
electric trains and trams, as well as other types of electric transport;
transformers;
most display devices, such as computers, laptops or televisions;
all household appliances powered by electricity;
sockets, electric meters and much more.

Thus, electromagnetic radiation surrounds us everywhere: we cannot hide or run away from it.

Harm of electromagnetic radiation

Scientists have long observed electromagnetic radiation and, in the end, have come to the conclusion that waves of different strengths and lengths can have a negative effect on human health. The tissues of the human body are quite susceptible to electromagnetic impulses, and the body's response to their effects depends on the following criteria:

radiation power;
type of waves;
duration of stay in the range of electromagnetic waves.

Electromagnetic waves cause oscillation of particles of body tissues, resulting in overheating. However, human organs have different densities, due to which their susceptibility to EM pulses is different. The following tissue types are most susceptible to negative changes:

eyes;
brain;
intestines;
gall bladder;
bladder.

In people, forced for a long time under the influence of electromagnetic radiation, the following diseases were most often diagnosed:

visual impairment, including cataracts;
problems with pressure and cardiac activity;
blood diseases, as a result of which the destruction of red blood cells occurs;
chronic headaches;
endocrine diseases;
feeling of chronic fatigue;
depressive disorders.

Of particular danger is electromagnetic radiation for pregnant women in the early stages of bearing a child. At this stage, waves of different frequencies can cause disturbances in the formation of the internal organs of the fetus. As a result, irreversible deformities develop, underdevelopment of internal organs or a complete halt to the development of the embryo and its further death. Also no less dangerous are electromagnetic waves for men. They contribute to the development of problems with potency, inhibit the activity of sperm, which ultimately leads to infertility.

Infrared radiation is considered one of the most dangerous. During its impact on humans and the environment, overheating of body tissues occurs. If the temperature rises above 42 degrees, the internal organs begin to fail in the victim, irreversible changes in the blood occur, which ultimately leads to death. No less dangerous is ultraviolet radiation, the abuse of which can cause skin cancer. In addition to the above, electromagnetic waves affect the human brain, increasing the risk of developing diseases such as Alzheimer's disease in the elderly.

Physical and psychological effects

It is no secret that some people are more susceptible to electromagnetic radiation than others. This is mainly manifested in increased sensitivity to changes in the electromagnetic field of the earth, due to which such people are called meteorological. If such a person is forced to stay close to a source of strong radiation for a long time, then first of all he suffers from the nervous system and mental health. Common psychological and nervous problems caused by electromagnetic waves include:

memory impairment;
depression
frequent mood swings.

According to scientists, people with increased sensitivity to electromagnetic radiation are more likely than others to suffer from panic attacks and unreasonable fears, and are also more prone to suicides. It is important to note that not only older people, but also young people can suffer from hypersensitivity. A huge role in this is played by the hereditary factor.

Methods of protection against the negative effects of electromagnetic radiation

Despite the fact that electromagnetic waves are an integral part of our life, nevertheless, there are many ways to protect ourselves and our loved ones from their negative effects. To reduce the risk of electromagnetic radiation, it is important to remember the following rules:

try to avoid prolonged exposure to high voltage power lines, and also near transformer booths or powerful microwave sources. It is not worth buying plots or building houses next to a similar source, it is also not recommended to start a garden or a garden in such places;
if contact with strong electromagnetic radiation cannot be avoided, buy a special device that allows you to measure the field level;
remember that electronic devices must operate for a strictly limited time. If you are not watching TV or sitting at a computer, turn them off;
schedule a stay at the computer for yourself and your children. Scientists recommend spending no more than 2 hours daily behind a monitor;
if you do not use the Internet, turn off the Wi-Fi router in the house;
place household appliances, including TV, at least 3 meters from your berth;
do not let your children play with phones or tablets.

In addition to the above, experts recommend checking the level of radiation coming from your wiring and switches. If you are really interested in the safety of your home, you can invite a specialist from the laboratory with special equipment who will measure the background and tell you which of the devices carries the greatest threat. This is the most effective protection against electromagnetic fields and radiation.

Important! Scientists have not yet invented protection against electromagnetic waves, but in some stores, including the Internet, you can find special devices aimed at suppressing the electromagnetic field. All these "inventions" are a commercial move, and relate to absolutely useless things.

There is no way to completely get rid of the electromagnetic field, but do not overestimate the harm of electromagnetic radiation. Our body is designed for weak exposure to electromagnetic impulses, and DNA can repair damaged areas on its own. Thus, if the level of exposure to the electromagnetic field is below normal, then a person should not be afraid of it.

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

As a result, according to the official data of the WHO (World Health Organization), EMR is considered dangerous if the exposure is too long.

Radiation sources - This is mobile electronics, telephone towers, transformers and many other electronic devices. It is impossible to protect against electromagnetic radiation. It is found in natural quantities in the natural field of the earth. For example, the result of electromagnetic radiation in the atmosphere is ion flashes during the northern lights.

But if the effect of electromagnetic radiation on a person is negative, how to maintain their health and compensate for unpleasant ailments?

Sources of electromagnetic radiation

The more electronics are produced, the more the number of sources of EMP is received by mankind. You can’t demand to stop the process of technologicalization: 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 who are in a coma, and in these cases the effect of EMR is negligible.

If you need to avoid sources of radiation, the only way out is simply not to buy certain objects or not to approach the following series of influential things:

mobile phones;
tablets
LCD TVs;
energy-saving lamps;
transformer booths;
large electrical cables;
sockets;
refrigerators;
home electric generators;
devices for brain tomography;
and much more.

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

Results of various studies

In the USSR, Spain, the USA, Great Britain and other states, studies were conducted on the effect of electromagnetic radiation on children and adults. Here are the basic facts about radiating devices that were identified during the experiments.

How does radiation affect the embryo?

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

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

Another group of researchers, which did not spend so much time with electronics, showed a much lower rate of miscarriages. The study was conducted in the United States in the early 2000s. Now computer technology has stepped forward, and the waves have become less dangerous for humans.

Children who spoke on the phone for 20 minutes, then for 2 hours showed changes in brain activity. For verification, a group of 11-13 years was taken. The experiment was staged in Britain in the 90s.

The same experts, but later tested for the effects of computers on children and adults. Children about 10 years old showed changes in blood and EEG, similar to deviations of cancer patients, after half an hour. Adolescents - after an hour, and adults - after 2 hours. The changes came to naught during the same time.

Experts at the University of Bristol proved that the reaction rate in children 11-14 years old, constantly using the phone, reduces by 1.5-2 times. Similar results were found by Finnish studies studying the effects of electromagnetic fields and radiation on the human body.

In the USSR, animal experiments were conducted. 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, that EMR really has 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 EMP

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

Induction or irradiation occurs when the motion of electrons is not uniform inside a confined space. Electrons are also part of the human body, with the result that a microscopic magnetic and electronic field also appears around a person.

Electromagnetic radiation affects a person by changing his natural field. Certain vital functions depend on the field. For example, intrinsic electromagnetic radiation affects the reaction rate of neurons, brain activity, and reaction.

With external exposure, leading to violations of the natural levels of the waves, the functions go astray. As a result, the body begins to hurt, showing various dysfunctions associated with EMR.

What is affected by radiation

The waves emitted by electrical devices and natural sources affect most parts of the human body:

reproductive system;
cardiovascular system;
endocrine organs;
immunity departments
nervous system;
brain.

Each department in its own way suffers from constant doses of radiation. And even though the waves are less dangerous than radiation is generally considered, the EMR problem is more relevant: the induction of waves surrounds us at every step, and therefore is more dangerous.

The effect of EMR on the brain

Studies of prestigious English 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 in the opposite direction are transmitted more slowly. Part of the information is lost along the road, resulting in failures: convulsions, distraction, improper machine movements.

Decreases, especially in children, the reaction rate. This leads to an increase in the risk of death due to accidents, an end to a sports career. Waves adversely affect brain activity, temporarily exerting a dulling effect on a person.

Reproductive system side effects

With the constant effect 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 - sperm cells - stick together, making it harder to conceive a child. In women, the menstrual cycle goes astray.

People with "electric" professions (repairman of transformer booths, electrician, IT specialist) are more likely to have children with developmental abnormalities.

Inhibition 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 blood flow slows down, the brain and other organs suffer from oxygen starvation.

Because of their insufficient nutrition, vision deteriorates sharply, the heart begins to "naughty." People who are prone to heart attacks are at greater risk of their occurrence when working with PCs and mobile devices.

Endocrine changes

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

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

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

Conclusion on the effect of radiation on humans

It is impossible to say unequivocally that you should abandon all electronic devices at once and go to a healthy lifestyle. It is impossible to refuse to use them. It’s easier to follow simple guidelines that can reduce the negative effects of electronics.

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

Electromagnetic radiation (EMP) accompanies a modern person everywhere. Any technique whose operation is based on electricity emits waves of energy. Some types of such radiation are constantly talked about - this is radiation, and ultraviolet radiation, the danger of which has long been known to everyone. But about the effect of electromagnetic fields on the human body, if it is 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 at stake. A school physics course talks about how energy travels in the form of waves. Depending on their frequency and length, a large number of types of radiation are distinguished. So electromagnetic waves include:

High frequency radiation. It includes x-rays and gamma rays. They are also known as ionizing radiation.
Mid-frequency radiation. This is the visible spectrum that people perceive as light. In the upper and lower frequency scale are ultraviolet and infrared radiation.
Low frequency radiation. It includes radio and microwaves.

To explain the effect of electromagnetic radiation on the human body, all these species 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, in biological organisms, the structure of cells is disrupted, DNA is modified and tumors appear.
Non-ionizing radiation has long been considered harmless. But recent studies by scientists demonstrate that with great 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 emit any electronic equipment. In addition, we must not forget about the power lines along which the most powerful charges of electricity pass. EMR also emit transformers, elevators and other technical devices that provide comfortable living conditions.

Thus, it is enough to turn on the TV or talk on the phone so that 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.

EMR measuring devices

To determine how much a particular source of electromagnetic radiation affects the body, devices for measuring electromagnetic fields are used. The simplest and most widely known is the 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 out its numerical characteristics. Then they can be written to a computer and processed using various examples of measured quantities and frequencies.

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

More accurate and detailed tables are presented in GOST and SanPiNah. You can find formulas in them, thanks to which you can calculate how dangerous the source of electromagnetic radiation 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 x-rays per hour), then the EMP is in V / m 2 (volts per square meter of area). 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;
Over 0.3 GHz - 10 μV / cm 2.

It is thanks to the measurements of these indicators that the safety for a person of one or another source of electromagnetic radiation is determined.

How does electromagnetic radiation affect a person?

Considering that many people have been in constant contact with electrical devices since childhood, a logical question arises: is electromagnetic radiation 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. Over 50 years of research have shown that the electromagnetic field of a person changes under the influence of other radiation. This leads to the development of the so-called "radio wave disease."

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

According to statistics from 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;
headaches;
impaired concentration of attention;
dizziness.

At the same time, the negative effect of electromagnetic radiation on human health is most dangerous because doctors still cannot diagnose it. After examining and passing tests, 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 differently to electromagnetic effects. The central nervous system is most sensitive to the effects of electromagnetic fields on humans.

EMR worsens signal permeability through neurons in the brain. As a result, it affects the activity of the body as a whole.

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

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

Red blood cells, 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 fulfillment of the transport function of blood.

EMR also reduces the permeability of cell membranes. As a result, all tissues that are exposed to radiation do not receive the necessary oxygen and nutrients. In addition, the effectiveness of hematopoietic functions is reduced. The heart, in turn, responds to this problem with arrhythmia and a drop in myocardial conduction.

The influence of electromagnetic waves on the human body destroys immunity. Due to the clumping of blood cells, lymphocytes and white blood cells are blocked. Accordingly, the infection simply does not meet the opposition of protective systems. As a result, not only increases the frequency of colds, but also exacerbates chronic ailments.

Another consequence of harm from electromagnetic radiation is a violation of hormone production. Exposure to the brain and circulatory system stimulates the pituitary, adrenal glands and other glands.

The reproductive system is also sensitive to electromagnetic radiation, the impact on humans can be catastrophic. Considering hormone production disorders, potency in men 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 disturbance of the electromagnetic field can disrupt the normal process of cell division, damaging the DNA. The result is pathologies of children's development.

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

Given that modern medicine can hardly counter radio wave disease, you must try to protect yourself on your own.

EMP protection

Considering all the possible harm that the influence of the electromagnetic field brings to living organisms, simple and reliable safety rules have been developed. At enterprises in which a person constantly encounters high levels of electromagnetic radiation, workers have special protective shields and equipment.

But at home, the sources of the electromagnetic field cannot be screened like this. It will be at least 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 effect of the electromagnetic field on human health:

Stay as far away from EMP sources as possible. For power lines, 25 meters is enough. A monitor or TV screen is dangerous if it is located closer than 30 cm away. Smartphones and tablets are not enough to be carried in pockets, but in purses or purses 3 cm from the body.
Reduce contact time with EMP. This means that you do not have to stand for long near working sources of electromagnetic fields. Even if you want to follow the cooking on an electric stove or bask in the heater.
Turn off unused appliances. This will not only reduce the level of electromagnetic radiation, but also help to save money on electricity bills.

You can still carry out a set of preventive measures so that the effect 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. Then the emitters can be distributed around the room to reduce the load on individual sections of the area. It is also important to consider that the steel casing shields EMP well.

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

Modern science has divided the material world around us into matter and field.

Does the substance interact with the field? Or maybe they coexist in parallel and electromagnetic radiation does not affect the environment and living organisms? Let's find out how electromagnetic radiation affects the human body.

Duality of the human body

Life on the planet was born under the influence of abundant electromagnetic background. For millennia, this background has not undergone significant changes. The influence of the electromagnetic field on the various functions of a wide variety of living organisms was stable. This applies to both its simplest representatives and the most highly organized beings.

However, as humanity “matured”, the intensity of this background began to continuously increase due to artificial technogenic sources: electric power transmission lines, household electrical appliances, radio relay and cellular lines, and so on. The term "electromagnetic pollution" (smog) arose. Under it is understood the totality of the entire spectrum of electromagnetic radiation that has a negative biological effect on living organisms. What is the mechanism of influence of electromagnetic fields on a living organism, and what could be the consequences?

In search of an answer, we will have to accept the concept that a person possesses not only a material body, consisting of an unimaginably complex combination of atoms and molecules, but also has another component - an electromagnetic field. It is by the presence of these two components that a person’s connection with the outside world is ensured.

The impact of the electromagnetic web on the field of a person affects his thoughts, behavior, physiological functions and even vitality.

A number of modern scientists believe that diseases of various organs and systems occur due to the pathological effects of external electromagnetic fields.

The spectrum of these frequencies is very wide - from gamma radiation to low-frequency electrical vibrations, therefore, the changes caused by them can be very diverse. The nature of the consequences is affected not only by the frequency, but also the intensity, as well as the exposure time. Some frequencies cause thermal and informational effects, others have a destructive effect at the cellular level. In this case, decay products can cause poisoning of the body.

The norm of electromagnetic radiation for humans

Electromagnetic radiation becomes a pathogenic factor if its intensity exceeds the maximum permissible norms verified by many statistical data for humans.

For radiation sources with frequencies:

Radio and television equipment, as well as cellular communications, operate in this frequency range. For high voltage transmission lines, the threshold value is 160 kV / m. With an intensity of electromagnetic radiation exceeding the indicated values, negative health consequences are very likely. Actual power line voltage values \u200b\u200bare 5–6 times less than the dangerous value.

Radio wave disease

As a result of clinical studies begun back in the 60s, it was found that under the influence of electromagnetic radiation on a person, changes occur in his body in all the most important systems. Therefore, it was proposed to introduce a new medical term - “radio wave disease”. According to researchers, its symptoms are already spreading to a third of the population.

Its main manifestations - dizziness, headaches, insomnia, fatigue, deterioration in concentration, depression - are not particularly specific, therefore, the diagnosis of this disease is difficult.

However, in the future, this symptom develops into serious chronic diseases:

cardiac arrhythmia;
fluctuations in blood sugar;
chronic respiratory diseases, etc.

To assess the degree of danger of electromagnetic radiation to humans, consider its effect on different body systems.

The impact of electromagnetic fields and radiation on the human body

The nervous system of a person is very sensitive to electromagnetic effects. Nerve cells of the brain (neurons) as a result of the "intervention" of external fields worsen their conductivity. This can provoke severe and irreversible consequences for the person himself and his environment, since the changes affect the holy of holies - the highest nervous activity. But it is she who is responsible for the entire system of conditioned and unconditioned reflexes. In addition, memory is deteriorating, the coordination of brain activity with the work of all parts of the body is disturbed. Mental disturbances are very likely right up to delusions, hallucinations and attempts at suicide. Violation of the adaptive ability of the body is fraught with exacerbation of chronic diseases.
The reaction of the immune system to the effects of electromagnetic waves is very negative. There is not only a suppression of immunity, but also an attack of the immune system on your own body. Such aggression is explained by a drop in the number of lymphocytes, which should ensure victory over the infection invading the body. These "valiant warriors" also fall prey to electromagnetic radiation.
In a person’s state of health, blood quality is paramount. What is the effect of electromagnetic radiation on blood? All elements of this life-giving fluid have certain electrical potentials and charges. The electrical and magnetic components that form electromagnetic waves can cause the destruction or, on the contrary, coalescence of red blood cells, platelets, and cause obstruction of cell membranes. And their effect on the hematopoietic organs causes disturbances in the work of the whole hematopoietic system. The body's response to such a pathology is the release of excessive doses of adrenaline. All these processes have a very negative effect on the work of the heart muscle, blood pressure, myocardial conduction and can cause arrhythmia. The conclusion is not comforting - electromagnetic radiation has an extremely negative effect on the cardiovascular system.
The impact of the electromagnetic field on the endocrine system leads to the stimulation of the most important endocrine glands - the pituitary gland, adrenal glands, thyroid gland, etc. This causes malfunctions in the production of the most important hormones.
One of the consequences of disorders in the nervous and endocrine system are negative changes in the genital area. If we evaluate the degree of influence of electromagnetic radiation on male and female sexual function, then the sensitivity of the female reproductive system is much higher to electromagnetic effects than men. Associated with this is the danger of exposure to pregnant women. Pathologies of the development of the child at different stages of pregnancy can be manifested in a decrease in the rate of development of the fetus, malformations in the formation of various organs, and even lead to premature birth. The first weeks and months of pregnancy are especially vulnerable. The embryo is still not firmly fixed to the placenta and the electromagnetic “blow” can interrupt its connection with the mother’s body. In the first three months, the most important organs and systems of the growing fetus are formed. And the disinformation that external electromagnetic fields can bring can distort the material carrier of the genetic code - DNA.

How to reduce the negative effects of electromagnetic radiation

The listed symptoms indicate the strongest biological effect of electromagnetic radiation on human health. The danger is compounded by the fact that we do not feel the impact of these fields and the negative effect accumulates over time.

How to protect yourself and your loved ones from electromagnetic fields and radiation? The implementation of the following recommendations will minimize the consequences of the operation of electronic appliances.

Our everyday life includes more and more diverse equipment that facilitates and decorates our lives. But the effect of electromagnetic radiation on humans is not a myth. Champions in terms of impact on humans are microwave ovens, electric grills, cell phones and some models of electric shavers. It is almost impossible to abandon these benefits of civilization, but one should always remember the rational exploitation of all the technology around us.

Technological progress has a downside. The global use of various techniques powered by electricity has caused pollution, which has been given the name electromagnetic noise. In this article, we will consider the nature of this phenomenon, the degree of its effect on the human body, and protective measures.

What is it and radiation sources

Electromagnetic radiation is electromagnetic waves that occur when a magnetic or electric field is disturbed. Modern physics interprets this process in the framework of the theory of wave-particle duality. That is, the minimum portion of electromagnetic radiation is a quantum, but at the same time it has frequency-wave properties that determine its main characteristics.

The frequency spectrum of electromagnetic radiation, allows you to classify it into the following types:

radio frequency (these include radio waves);
thermal (infrared);
optical (that is, visible to the eye);
radiation in the ultraviolet spectrum and hard (ionized).

A detailed illustration of the spectral range (electromagnetic radiation scale) can be seen in the figure below.

The nature of radiation sources

Depending on the origin, it is customary to classify sources of electromagnetic waves in world practice into two types, namely:

disturbances of the electromagnetic field of artificial origin;
radiation from natural sources.

Radiations emanating from a magnetic field, the field around the Earth, electrical processes in the atmosphere of our planet, nuclear fusion in the bowels of the sun - they are all of natural origin.

As for artificial sources, they are a side effect caused by the operation of various electrical mechanisms and devices.

The radiation emanating from them can be low-level and high-level. The degree of radiation intensity of the electromagnetic field completely depends on the power levels of the sources.

As an example of sources with a high level of electromagnetic radiation, we can cite:

Power lines are usually high voltage;
all types of electric vehicles, as well as related infrastructure;
tV and radio towers, as well as mobile and mobile communications stations;
installations for converting the voltage of the electric network (in particular, the waves emanating from a transformer or distribution substation);
elevators and other types of lifting equipment where an electromechanical power plant is used.

Typical sources emitting low-level radiation include the following electrical equipment:

almost all devices with a CRT display (for example: payment terminal or computer);
various types of household appliances, from irons to climate systems;
engineering systems that supply electricity to various objects (not only power cables are meant, but related equipment, such as sockets and electricity meters).

Separately, it is worth highlighting the special equipment used in medicine, which emits hard radiation (X-ray machines, MRI, etc.).

Human impact

In the course of numerous studies, radiobiologists came to a disappointing conclusion - prolonged emission of electromagnetic waves can cause an “explosion” of diseases, that is, it causes a rapid development of pathological processes in the human body. Moreover, many of them introduce violations at the genetic level.

Video: How electromagnetic radiation affects people.
https://www.youtube.com/watch?v\u003dFYWgXyHW93Q

This is due to the fact that the electromagnetic field has a high level of biological activity, which negatively affects living organisms. The influence factor depends on the following components:

the nature of the radiation produced;
how long and with what intensity it lasts.

The effect on radiation of human health of radiation, which has an electromagnetic nature, is directly dependent on localization. It can be both local and general. In the latter case, large-scale irradiation occurs, for example, radiation produced by power lines.

Accordingly, local exposure means exposure to certain parts of the body. Electromagnetic waves emanating from an electronic clock or mobile phone, a vivid example of local exposure.

Separately, it is necessary to note the thermal effect of high-frequency electromagnetic radiation on living matter. Field energy is converted into thermal energy (due to vibration of molecules), on this effect the basis is the work of industrial microwave emitters used to heat various substances. In contrast to the benefits in production processes, thermal effects on the human body can be detrimental. From the point of view of radiobiology, it is not recommended to be near "warm" electrical equipment.

It must be taken into account that in everyday life we \u200b\u200bare regularly exposed to radiation, and this happens not only at the factory, but also at home or when moving around the city. Over time, the biological effect accumulates and intensifies. With an increase in electromagnetic noise, the number of characteristic diseases of the brain or nervous system increases. Note that radiobiology is a fairly young science, so the harm caused to living organisms from electromagnetic radiation has not been thoroughly studied.

The figure shows the level of electromagnetic waves produced by conventional devices used in everyday life.

Please note that the field strength level decreases significantly at a distance. That is, to reduce its effect, it is enough to move away from the source at a certain distance.

The formula for calculating the norm (standardization) of electromagnetic field radiation is indicated in the relevant GOSTs and SanPiNah.

Radiation protection

In production, absorbing (protective) screens are actively used as a means of protecting against radiation. Unfortunately, it is not possible to protect oneself from electromagnetic radiation with the help of such equipment at home, since it is not designed for this.

in order to reduce the effect of electromagnetic field radiation to almost zero, you should move away from power lines, radio and television towers at a distance of at least 25 meters (you must take into account the source power);
for a CRT monitor and TV, this distance is much less - about 30 cm;
electronic watches should not be placed close to the pillow, the optimal distance for them is more than 5 cm;
as for radio and cell phones, bringing them closer than 2.5 centimeters is not recommended.

Note that many people know how dangerous it is to stand near high-voltage power lines, but at the same time most people do not attach importance to ordinary household electrical appliances. Although it is enough to put the system unit on the floor or move it away, and you will protect yourself and your loved ones. We advise you to do this, and then measure the background from the computer using an electromagnetic field radiation detector to visually verify its decrease.

This advice also applies to the placement of the refrigerator, many people put it near the kitchen table, practical, but unsafe.

No table will be able to indicate the exact safe distance from a particular electrical equipment, since the radiation can vary, both depending on the model of the device and the country of manufacture. At the moment there is no single international standard, therefore, in different countries the norms can have significant differences.

You can accurately determine the radiation intensity using a special device - a fluxmeter. According to the standards adopted in Russia, the maximum permissible dose should not exceed 0.2 μT. We recommend that you measure in the apartment using the above instrument to measure the degree of electromagnetic field radiation.

Fluxmeter - a device for measuring the degree of radiation of an electromagnetic field

Try to reduce the time when you are exposed to radiation, that is, do not stay for a long time near working electrical appliances. For example, it is not at all necessary to constantly stand by an electric stove or microwave oven while cooking. Regarding electrical equipment, you can see that warm does not always mean safe.

Always turn off unused electrical appliances. People often leave various devices turned on, not taking into account that at this time electromagnetic radiation is coming from electrical engineering. Turn off your laptop, printer or other equipment, it is unnecessary to be exposed again, remember about your safety.
