The influence of an electromagnetic pulse on a person. The influence of electromagnetic radiation on human health

In recent years, due to the development of technology, the human body is exposed to a high level of exposure electromagnetic radiation(EMP), which could not but cause serious concern throughout 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 atoms in 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 impact can lead to irreversible consequences.

Invisible danger

Publications in the scientific literature have 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 the home, at work, in educational and public institutions. Despite numerous problems in establishing conclusive evidence scientific evidence harm and gaps in understanding the exact mechanisms of its occurrence, epidemiological analysis increasingly suggests a significant potential for traumatic effects produced by non-ionizing radiation. Protection against electromagnetic radiation is becoming increasingly important.

Because medical education does not emphasize environmental health, some physicians are not fully aware of the potential health problems associated with EMR and, as a result, non-ionizing radiation events may be misdiagnosed and treated ineffectively.

While the possibility of damage to tissues and cells associated with exposure to X-ray radiation is beyond doubt, the impact of electromagnetic radiation on living organisms, when it comes 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. Electromagnetic radiation energy exists in various forms, each of which has different physical properties. They can be measured and expressed using frequency or wavelength. Some waves have a high frequency, others have a medium frequency, and others have a low frequency. The range of electromagnetic radiation includes many different forms of energy coming from different sources. Their name is used to classify types of EMR.

The short wavelength of electromagnetic radiation, corresponding to high frequency, is a characteristic of gamma rays, x-rays and ultraviolet radiation. More spectrum includes 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 undetectable to humans. Their detection requires measuring electromagnetic radiation using special instruments, and, as a result, people cannot assess the extent of exposure to energy fields in these ranges.

Despite the lack of perception, exposure to high-frequency energy, including X-rays, called ionizing radiation, is potentially harmful to human cells. By changing 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 malignancy or cell death.

Anthropogenic EMP

The effect of electromagnetic radiation on the body, especially non-ionizing radiation, which refers to forms of energy with lower frequencies, has been underestimated by many scientists. It was not believed to produce adverse effects at normal exposure levels. IN Lately However, growing evidence suggests that some frequencies of non-ionizing radiation may potentially cause biological harm. Most studies of their health effects have focused on the following three main types of anthropogenic EMR:

  • 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 frequency of electromagnetic radiation is in the range of 3-150 kHz (propagated and re-radiated by wiring).

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

EMR and human health

While studies examining the negative effects of electromagnetic radiation have sometimes produced conflicting results, findings of reproductive dysfunction and cancer susceptibility appear to support suspicions that EMF exposure may pose a threat to human health. Adverse pregnancy outcomes, including miscarriages, stillbirths, preterm births, altered sex ratios, and congenital anomalies have all been associated with influence of EMR on the mother.

A large prospective study published in the journal Epidemiology, for example, reported peak EMR exposure in 1,063 pregnant women in the San Francisco area. Participants in the experiment wore detectors magnetic field, and 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 EMR frequencies may be carcinogenic have been studied. For example, the International Journal of Cancer recently published an important case-control study on the association between childhood leukemia and magnetic fields in Japan. By assessing levels of electromagnetic radiation in bedrooms, scientists confirmed that high levels of exposure lead to a significantly greater risk of 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 constant psychological stress and fear of being affected by EMP. Many patients become incapacitated by the mere thought that an invisible wireless signal at any time and anywhere can provoke painful sensations in their body. Constant fear and preoccupation with health problems affect well-being up to the development of phobia and fear of electricity, which in some people makes them want to leave civilization.

Mobile phones and telecommunications

Cell phones transmit and receive signals using EMFs, which are 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 problem in extrapolating results from their use in experimental rodent studies is that the frequency of maximum absorption of RF energy depends on body size, shape, orientation and position.

Resonant absorption in rats is in the range of microwaves 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 absorbed dose rate, but poses a problem for those studies in which only the external field strength is used to determine the level of exposure.

The relative depth of penetration in laboratory animals compared to the size of the human head is greater, and the tissue parameters and the mechanism of heat redistribution differ. Another potential source of inaccuracy in exposure levels is the effect of radiofrequency radiation on the cell.

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. Research into radiation effects on technical personnel began with the start of construction of the first 220 kV power lines, when cases of deteriorating health of workers appeared. The commissioning of 400 kV power lines led to the publication of numerous works in this area, which subsequently became the basis for the adoption of the first regulations limiting the effect of the 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 consists of endothelial cells associated with the zona septa, 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 harmful to health.

Ambient temperatures that exceed the limits of mammalian thermoregulation increase the permeability of the blood-brain barrier to macromolecules. Neuronal uptake of albumin into various areas brain depends on its temperature and manifests itself when it increases by 1 ° C or higher. Since sufficiently strong radiofrequency fields can lead to tissue heating, it is logical to assume that the influence of electromagnetic radiation on humans results in 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 believing that they are being affected by EMR. This has led to speculation that electromagnetic fields may interfere with normal sleep patterns, with attendant health consequences. The potential risk of sleep disturbance must be considered in light of the fact 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, regular alternation of states of wakefulness and rest is a necessary requirement for ensuring proper operation brain, metabolic homeostasis and immune system.

In addition, sleep appears to be precisely the physiological system whose study will make it possible to clarify the influence of high-frequency electromagnetic radiation on humans, since in this biological state the body reacts sensitively to external stimuli. There is evidence that weak EMFs, the intensity of which is well below that which would cause a rise in temperature, can also cause biological effects.

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

Negative manifestations

Thus, the influence of electromagnetic radiation on humans, even non-ionizing ones, occurs, 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 disruption (wakefulness - sleep) by interfering with the functioning of the pineal gland and creating hormonal imbalance, changes in heart rate and blood pressure, worsening immunity to pathogens, causing weakness, exhaustion, growth problems, DNA damage and cancer.

It is recommended to construct buildings away from EMI sources, and protection from electromagnetic radiation of high-voltage power lines must be mandatory. In cities, cables must be laid underground, and equipment that neutralizes the effects of EMR must be used.

Based on the results of a correlation analysis based on experimental data, it was concluded that the influence of electromagnetic radiation from power lines on humans can be significantly reduced 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 also influenced by the terrain under the power line.

Precautionary measures

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

  • Children should not be allowed to play near power lines, transformers, satellite transmitters, or microwave sources.
  • Places where the density exceeds 1 mG should be avoided. It is necessary to measure the EMF level of devices in the off and operating state.
  • It is necessary to rearrange the office or home in such a way as not to be exposed to the field of electrical appliances and computers.
  • You should not sit too close in front of the computer. Monitors vary greatly in the strength of their EMR. You should not stand near someone working microwave oven.
  • Move electrical appliances at least 2 m from the bed. Wiring should not be allowed under the bed. Remove dimmers and 3-way switches.
  • Precautions should be taken when using cordless devices such as electric toothbrushes and razors.
  • It is also recommended to wear as little jewelry as possible and remove it at night.
  • It is also necessary to remember that EMR passes through walls, and take into account sources in the next room or behind the walls of the room.

Electromagnetic radiation - habitat habitat of all life on our planet: electromagnetic waves are emitted by outer space above us, Sun rays, lightning strikes, household appliances and even living creatures. Moreover, if there were no electromagnetic field Earth, there would be no life itself. Unfortunately, electromagnetic pulses can be both beneficial and harmful. It is worth understanding that the human body is an excellent source of receiving electromagnetic radiation, which means that a long stay in an area of ​​strong influence simply cannot pass without leaving a trace for us. Let's figure out what the influence of electromagnetic radiation on the human body is, and how to protect yourself from it.

Electromagnetic radiation and its sources

This type of radiation occurs as a result of particle oscillations 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. Today 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 many more types of radiation, since their eyes are more receptive than humans;
  • infrared radiation– this type of radiation is not perceived by the human eye. The most well-known sources of this type of wave are the sun and large industrial devices;
  • radio waves– radio waves are considered the longest. They are the ones that come from microwave ovens and many other household appliances;
  • UV radiation– Ultraviolet radiation also refers to electromagnetic waves. Sources of UV radiation are the sun's rays, solarium lamps, stars, and laser systems. It is believed that UV waves are a natural source of radiation that can have the maximum effect 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 wide range length and high penetrating ability;
  • gamma radiation- the shortest wavelength, 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 any objects and pass through them. In addition, prolonged exposure to gamma rays can cause irreversible changes and even mutations in the body.

It is worth noting that the earth’s magnetic field is also one of the strongest emitters of electromagnetic waves. However, in in this case exposure to electromagnetic radiation does not have a critical effect on the human body. Over thousands of years of life, humanity has made a huge step forward, having learned to create complex technical devices and understanding the power of many natural phenomena. Unfortunately, some of man's creations, in addition to their benefits, carry potential danger in the form of electromagnetic radiation. The most well-known 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 devices with a display, such as computers, laptops or televisions;
  • all household appliances powered by electricity;
  • sockets, electricity meters and much more.

Thus, electromagnetic radiation surrounds us everywhere: it is impossible to hide or run away from it.

Harm from electromagnetic radiation

Scientists have been observing electromagnetic radiation for a long time and, in the end, came 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 pulses, and the body’s reaction to their influence depends on the following criteria:

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

Electromagnetic waves cause particles in the body's tissues to vibrate, causing them to overheat. However, human organs have different densities, due to which their susceptibility to EM impulses differs. The following types of tissues are most susceptible to negative changes:

  • eyes;
  • brain;
  • intestines;
  • gallbladder;
  • bladder.

The following diseases were most often diagnosed in people forced to be exposed to electromagnetic radiation for a long time:

  • visual impairment, including cataracts;
  • problems with blood pressure and heart function;
  • blood diseases that result in the destruction of red blood cells;
  • chronic headaches;
  • endocrine diseases;
  • feeling of chronic fatigue;
  • depressive disorders.

Electromagnetic radiation is especially dangerous for pregnant women in the early stages of pregnancy. On 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 stop in the development of the embryo and its further death. Electromagnetic waves are also no less dangerous for men. They contribute to the development of potency problems, inhibit sperm activity, which ultimately leads to infertility.

Infrared radiation is considered one of the most dangerous. During its impact on humans and the environment, body tissues overheat. If the temperature rises above 42 degrees, the victim’s internal organs begin to fail, irreversible changes occur in the blood, 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 older people.

Physical and psychological impact

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

  • memory impairment;
  • depression;
  • frequent mood changes.

According to scientific research, people with increased sensitivity to electromagnetic radiation are more likely than others to suffer from panic attacks and unreasonable fears, and are also most prone to suicide. It is important to note that not only older people, but also young people can suffer from hypersensitivity. The hereditary factor plays a huge role in this.

Methods of protection against the negative effects of electromagnetic radiation

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

  • Try to avoid prolonged exposure under high-voltage power lines, as well as near transformer boxes or powerful sources of microwave radiation. You should not buy land or build houses next to such sources, and it is also not recommended to start a garden or vegetable 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 the computer, turn them off;
  • Create a computer schedule for yourself and your children. Scientists recommend spending no more than 2 hours in front of the monitor daily;
  • If you don't use the Internet, turn it off Wi-Fi router in the house;
  • place household appliances, including a TV, at a distance of at least 3 meters from your sleeping place;
  • Don't let your children play with phones or tablets.

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

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

There is no way to completely get rid of the electromagnetic field, but you should not overestimate the harm of electromagnetic radiation. Our body is designed for weak exposure to electromagnetic pulses, 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.

ELECTROMAGNETIC RADIATION AND ELECTROMAGNETIC FIELDS - INVISIBLE KILLERS

We were taught at school that labor turned a monkey into a man, and scientific and technological progress is the engine of all humanity. It would seem that with its movement the quality and number of years lived by a person should improve. In fact, the deeper STP enters our lives, the harder our lives are and the more often people encounter previously unknown diseases, which appear and develop in direct progression along with technical progress. Let us not dispute that the benefits of civilization are bad. Let's talk about the hidden threat to humans and their descendants - electromagnetic radiation.

Research by scientists over the past decades shows that electromagnetic radiation is no less dangerous than atomic radiation. Electromagnetic smog, interacting with the electromagnetic field of the body, partially suppresses it, distorting it own field human body. This leads to a decrease in immunity, disruption of information and cellular exchange within the body, and the occurrence of various diseases. It has been proven that even at a relatively weak level, prolonged exposure to electromagnetic radiation can cause cancer, memory loss, Alzheimer's and Parkinson's diseases, impotence, destruction of the lens of the eye, and a decrease in the number of red blood cells. Electromagnetic fields are especially dangerous for pregnant women and children. Electromagnetic radiation contributes to sexual dysfunction in men and reproductive dysfunction in women.

American and Swedish scientists established a safe limit for human health on the intensity of electromagnetic fields - (0.2 µT). Eg, washing machine– 1 µT, microwave oven (at a distance of 30 cm) – 8 µT, vacuum cleaner – 100 µT, and when a train departs for the subway – 50-100 µT.

Scientists have long been talking about the negative impact of electromagnetic fields (EMF) on children’s bodies. Since the size of a child’s head is smaller than that of an adult, the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in an adult. This applies to mobile phones, which simply expose the brain to “local” overheating. Experiments on animals confirmed that with increasing doses of high-frequency radiation, literally welded areas formed in their brains. Research by US scientists has proven that the signal from the phone penetrates the brain to a depth of 37.5 mm, which creates interference in the functioning of the nervous system.

Growing and developing tissues are most susceptible to the adverse effects of the electromagnetic field. It is also biologically active in embryos. A pregnant woman working at a computer is exposed to almost the entire body, including the developing fetus, by EMF. By the way, those who think that laptop computers are practically safe are mistaken. Think carefully about the negative consequences of their exposure before placing a laptop computer on your stomach or lap. Yes, LCD screens do not have electrostatic field and do not carry x-rays, but a cathode ray tube is not the only source of electromagnetic radiation. Fields can be generated by a supply voltage converter, control circuits and information generation on discrete liquid crystal screens, and other equipment elements.

SO HARMFUL OR NOT?

When talking about EMFs, we can’t help but mention Wi-Fi. On the Internet you can find many articles on this subject: “Wi-Fi networks are dangerous to health”, “Does Wi-Fi have a harmful effect on the human body?”, “Radiation Wi-Fi networks harms trees, scientists say,” “Is Wi-Fi technology harmful to children?”

In the United States, there are examples of parents suing over Wi-Fi installed in schools and universities. Parents' fears that wireless networks cause irreparable harm to the health of children and adolescents, having a destructive effect on the growing body, are not unfounded. Wi-Fi, for example, operates at the same frequency as a microwave oven. For humans, this frequency is not at all as harmless as it seems. About 20,000 studies have been published recently. They prove the fact that Wi-Fi negatively affects the health of mammals, in particular, human health. Migraines, colds, joint pain, but most often, diseases caused by Wi-Fi include cancer, heart failure, dementia and memory impairment. In the US, UK and Germany, Wi-Fi is increasingly being abandoned in schools, hospitals and universities. The reason for the refusal is said to be harm to human health. Today, there is no official verdict in the case of Wi-Fi, as there was with the WHO recognition of the harm of mobile phones. After all, the revealed truth will bring considerable losses to those who are not interested in it. As they say: “Saving a drowning man is the work of the drowning man himself.” And the reader is right who, after reading an article about the dangers of Wi-Fi, wrote: “In the end, everyone decides for themselves why they are sick.”

ELIMINATE THE NEGATIVE ELECTROMAGNETIC INFLUENCE OF WI-FI

The impact of Wi-Fi on the human body, in contrast to mobile phone, not so noticeable. But if you still use wireless technologies to connect to the Internet or corporate network on an ongoing basis, give them up. Better get yourself a regular twisted pair cable. Try to reduce usage time wireless networks of any kind. Do not keep the source of electromagnetic radiation close to your body. Minimize the amount of time you use your mobile phone or Bluetooth headset. Use a wired connection. If you are pregnant, try to stay as far away from wireless networks as possible. No one has yet proven the harmful effects of Wi-Fi on pregnant women. But who knows how this know-how will affect the body of the unborn baby? After all real love for a child is not about buying another toy or beautiful clothes, but about raising a child strong and healthy.

At the Paracelsus Medical Center you can undergo diagnostics of the effects of electromagnetic influences on your body. At the same time, the equipment allows you to differentiate the types of electromagnetic influences - man-made, geopathogenic, radioactive, determine the degree of electromagnetic load (4 degrees in total) and effectively neutralize this negative effect on the body.

Every apartment is fraught with danger. We don’t even suspect that we live surrounded by electromagnetic fields (EMF), which a person can neither see nor feel, but this does not mean that they do not exist.

Since the very beginning of life, there has been a stable electromagnetic background (EMF) on our planet. For a long time it was practically unchanged. But, with the development of humanity, the intensity of this background began to grow at incredible speed. Power lines, an increasing number of electrical appliances, cellular communications - all these innovations have become sources of “electromagnetic pollution”. How does the electromagnetic field affect the human body, and what might be the consequences of this influence?

What is electromagnetic radiation?

In addition to the natural EMF created by electromagnetic waves (EMW) of various frequencies coming to us from space, there is another radiation - household radiation, which occurs during the operation of various electrical equipment found in every apartment or office. Every household appliance, take at least an ordinary hair dryer, passes through itself during operation. electricity, forming an electromagnetic field around. Electromagnetic radiation (EMR) is the force that appears when current passes through any electrical device, affecting everything that is near it, including a person, who is also a source of electromagnetic radiation. The greater the current passing through the device, the more powerful the radiation.

Most often, a person does not experience a noticeable impact of EMR, but this does not mean that it does not affect us. Electromagnetic waves pass through objects imperceptibly, but sometimes the most sensitive people feel a certain tingling or tingling sensation.

We all react differently to EMR. Some people’s bodies can neutralize its effects, while there are individuals who are maximally susceptible to this influence, which can cause various pathologies in them. Long-term exposure to EMR is especially dangerous for humans. For example, if his house is located near a high-voltage transmission line.

Depending on the wavelength, EMR can be divided into:

  • Visible light is the radiation that a person is able to perceive visually. Light wavelengths range from 380 to 780 nm (nanometers), meaning visible light wavelengths are very short;
  • Infrared radiation lies on the electromagnetic spectrum between light radiation and radio waves. The length of infrared waves is longer than light and is in the range of 780 nm - 1 mm;
  • radio waves. They are also microwaves that are emitted by a microwave oven. These are the longest waves. These include all electromagnetic radiation with waves longer than half a millimeter;
  • ultraviolet radiation, which is harmful to most living things. The length of such waves is 10-400 nm, and they are located in the range between visible and x-ray radiation;
  • X-ray radiation is emitted by electrons and has a wide range of wavelengths - from 8·10 - 6 to 10 - 12 cm. This radiation is known to everyone from medical devices;
  • Gamma radiation is the shortest wavelength (the wavelength is less than 2·10−10 m), and has the highest radiation energy. This type of EMR is the most dangerous for humans.

The picture below shows the entire spectrum of electromagnetic radiation.

Radiation sources

There are many EMR sources around us that emit electromagnetic waves into space that are not safe for the human body. It is impossible to list them all.

I would like to focus on more global ones, such as:

  • high-voltage power lines with high voltage, and a powerful level of radiation. And if residential buildings located closer than 1000 meters to these lines, the risk of cancer among residents of such houses increases;
  • electric transport - electric and metro trains, trams and trolleybuses, as well as ordinary elevators;
  • radio and television towers, the radiation of which is also particularly dangerous for human health, especially those installed in violation of sanitary standards;
  • functional transmitters - radars, locators that create EMR at a distance of up to 1000 meters, therefore, airports and weather stations try to be located as far as possible from the residential sector.

And on simple ones:

  • household appliances, such as a microwave oven, computer, TV, hair dryer, charging device, energy-saving lamps, etc., which are found in every home and are an integral part of our life;
  • mobile phones, around which an electromagnetic field is formed, affecting the human head;
  • electrical wiring and sockets;
  • medical devices - X-rays, computed tomographs, etc., which we encounter when visiting medical institutions that have the strongest radiation.

Some of these sources have a powerful effect on humans, others not so much. All the same, we have used and will continue to use these devices. It is important to be extremely careful when using them and be able to protect yourself from negative effects in order to minimize the harm they cause.

Examples of sources of electromagnetic radiation are shown in the figure.

Effect of EMR on humans

It is believed that electromagnetic radiation has a negative impact on both human health and his behavior, vitality, physiological functions and even thoughts. The person himself is also a source of such radiation, and if other, more intense sources begin to influence our electromagnetic field, then human body complete chaos may ensue, leading to various diseases.

Scientists have found that it is not the waves themselves that are harmful, but their torsion (information) component, which is present in any electromagnetic radiation, that is, it is the torsion fields that have the wrong effect on health, transmitting negative information to a person.

The danger of radiation lies in the fact that it can accumulate in the human body, and if you use, for example, a computer, mobile phone, etc. for a long time, then it is possible headache, high fatigue, constant stress, decreased immunity, and the likelihood of diseases of the nervous system and brain increases. Even weak fields, especially those that coincide in frequency with human EMR, can harm health by distorting our own radiation, and thereby causing various diseases.

Electromagnetic radiation factors have a huge impact on human health, such as:

  • source power and nature of radiation;
  • its intensity;
  • duration of exposure.

It is also worth noting that exposure to radiation can be general or local. That is, if you take a mobile phone, it affects only a separate human organ - the brain, but the radar irradiates the entire body.

What kind of radiation arises from certain household appliances, and their range, can be seen from the figure.

Looking at this table, you can understand for yourself that the further the radiation source is located from a person, the less its harmful effect on the body. If a hairdryer is in close proximity to the head, and its impact causes significant harm to a person, then the refrigerator has practically no effect on our health.

How to protect yourself from electromagnetic radiation

The danger of EMR lies in the fact that a person does not feel its influence in any way, but it exists and greatly harms our health. While workplaces have special protective equipment, things are much worse at home.

But it is still possible to protect yourself and your loved ones from the harmful effects of household appliances if you follow simple recommendations:

  • purchase a dosimeter that determines the intensity of radiation and measure the background from various household appliances;
  • do not turn on several electrical appliances at once;
  • keep your distance from them if possible;
  • place devices so that they are located as far as possible from places where people stay for a long time, for example, dining table or recreation areas;
  • children's rooms should contain as few radiation sources as possible;
  • there is no need to group electrical appliances in one place;
  • The mobile phone should not be brought closer to the ear than 2.5 cm;
  • Keep the telephone base away from the bedroom or desk:
  • do not be located close to a TV or computer monitor;
  • turn off devices you don't need. If you are not currently using a computer or TV, you do not need to keep them turned on;
  • try to reduce the time you use the device, do not stay near it all the time.

Modern technology has firmly entered our everyday life. We cannot imagine life without a mobile phone or computer, as well as a microwave oven, which many have not only at home, but also in the workplace. It’s unlikely that anyone will want to give them up, but it’s within our power to use them wisely.

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

Types of electromagnetic radiation

Before describing the danger of a particular type of radiation, it is necessary to understand what it is all about we're talking about. A school physics course teaches that energy travels in the form of waves. Depending on their frequency and length, they are distinguished a large number of types of radiation. So electromagnetic waves include:

  1. High frequency radiation. It includes X-rays and gamma rays. They are also known as ionizing radiation.
  2. Mid-frequency radiation. This is the visible spectrum, which people perceive as light. In the upper and lower frequency scales there are ultraviolet and infrared radiation.
  3. Low frequency radiation. This 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, the cell structure of biological organisms is disrupted, DNA is modified, and tumors appear.
  • Non-ionizing radiation has long been considered harmless. But recent research by scientists demonstrates that with high power and prolonged exposure, it is no less dangerous to health.

EMR sources

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

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

Devices measuring EMR

To determine how strongly a particular source of EMR affects the body, instruments are used to measure electromagnetic fields. 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 - flux meters. Such an electromagnetic radiation detector is able to determine the power of the source and provide its numerical characteristics. They can then be recorded on a computer and processed using various examples of measured quantities and frequencies.

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

More accurate and detailed tables are presented in GOSTs and SanPiNs. In them you can find formulas with which you can calculate how dangerous the EMR 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/m2 (volts per meter square area). The following indicators are considered a safe norm for humans, depending on the wave frequency, measured in hertz:

  • up to 300 kHz – 25 V/m2;
  • 3 MHz – 15 V/m2;
  • 30 MHz – 10 V/m2;
  • 300 MHz – 3 V/m2;
  • Above 0.3 GHz – 10 µV/cm2.

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

How does electromagnetic radiation affect humans?

Considering that many people have been in constant contact with electrical appliances, a logical question arises: is EMR that dangerous? Unlike radiation, it does not lead to radiation sickness and its effect is invisible. And is it worth complying with electromagnetic radiation standards?

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 by other radiation. This leads to the development of the so-called “radio wave disease”.

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

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

  • depression;
  • chronic fatigue;
  • insomnia;
  • headache;
  • disturbances in concentration;
  • 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 tests, the patient goes home with the diagnosis: “Healthy!” At the same time, if nothing is done, the disease will develop and enter the chronic stage.

Each organ system will respond to electromagnetic stimulation differently. The central nervous system is most sensitive to the effects of electromagnetic fields on humans.

EMR impairs the passage of the signal through the neurons of the brain. As a result, this affects the functioning of the body as a whole.

Also appear over time Negative consequences for the psyche - attention and memory are impaired, 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 impact and through 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, blockage of blood vessels occurs and the transport function of blood deteriorates.

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, reacts to this problem with arrhythmia and a drop in myocardial conductivity.

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

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

The reproductive system is also sensitive to electromagnetic radiation, the effect on a person can be catastrophic. Given the disturbances in the production of hormones, 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 miscarriage. And if this does not happen, then a disturbance in the electromagnetic field can disrupt the normal process of cell division, damaging DNA. The result is pathologies of child development.

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

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

EMI protection

Taking into account all the possible harm that the influence of the electromagnetic field brings on living organisms, simple and reliable safety rules have been developed. In enterprises in which a person constantly faces high levels EMP, special protective screens and equipment are provided for workers.

But at home, sources of electromagnetic fields cannot be shielded in this way. At the very least it will be inconvenient. Therefore, you should understand how to protect yourself in other ways. There are only 3 rules that must be followed constantly in order to reduce the impact of the electromagnetic field on human health:

  1. Stay as far away from EMR sources as possible. For power lines, 25 meters is sufficient. 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 the time of contact with EMR. This means that you do not need to stand for a long time near working sources of electromagnetic fields. Even if you want to supervise the cooking on an electric stove or warm up by the heater.
  3. Turn off electrical appliances that are not in use. This will not only reduce the level of electromagnetic radiation, but also help you save money on your energy bills.

You can also carry out a complex preventive measures so that exposure to electromagnetic waves is minimal. For example, having measured the radiation power of various devices using a dosimeter, you need to record the EMF readings. The emitters can then be distributed throughout the room to reduce the load on certain areas of the area. It is also important to consider that the steel case shields EMI well.

Do not forget that electromagnetic radiation in 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.
