Back in the early 60s of the 20th century, the negative impact of electromagnetic fields emanating from power lines on the human body was discovered. Scientists conducted a study in which people who were influenced by power lines at work took part. The results were alarming: all the subjects had irritability, impaired memory, sleep, increased fatigue.
Later, depression, frequent headaches, reduced immune defenses, muscle weakness, visual impairment, reduced potency, changes in blood composition, impaired perception of colors and orientation in space were added to this list. This list can go on and on.
The most serious problems that manifest themselves in the population living near power lines are oncology, reproductive disorders, both in women and men, as well as manifestations of the syndrome of increased electromagnetic sensitivity. The results of a study by foreign scientists of the influence of electromagnetic radiation on a child's body are simply sad. Scientists from Sweden and Denmark have proven that almost all children living at a distance of up to 150 meters from power lines, substations and subways have disorders of the nervous system. And what is most frightening is that such children are 2 times more likely to have leukemia (blood cancer).
In a number of foreign countries, the concept of "electromagnetic allergy" has appeared. Patients with such a diagnosis are given the opportunity to change their place of residence to a place more remote from electromagnetic sources. All expenses for resettlement are covered by the state.
What do power engineers themselves say about the dangers of power lines? Different power lines have different voltages. There are such concepts as dangerous and safe voltage. The distance at which the influence of the magnetic field from the power line is created is directly proportional to its power. How to find out the degree of tension? Everything is quite simple, you do not need to be an expert in this field. We look at the number of wires in the bundle. Not to be confused with the number of wires on the support. If two wires, the voltage is 330KV, three wires is 500KV, four wires is 750KV. To determine the smaller class, pay attention to the number of insulators. If there are from 3 to 5, the voltage is 35 kV, with a quantity of 6 to 8 - 110 kV and at 15 - 220 kV.
To protect people from the harmful effects of power lines, there are standards that establish the so-called sanitary zone. It originates from the extreme wire of the line, projected onto the surface of the earth. For Moscow and the Moscow region, the norms are as follows: voltage less than 20 kV - 10 m, 35 kV - 15 m, 110 kV - 20 m, 150-220 kV - 25 m, 330 - 500 kV - 30 m, 750 kV - 40 m. In view of these standards, land is allocated for construction. However, existing standards do not take into account the negative impact of electromagnetic fields.
Any sane person has a question: how to protect yourself and your loved ones from the negative impact of power lines? Here, too, everything is very simple. We multiply the listed standards by 10. What do we get? The power line with the lowest power will not adversely affect health at a distance of 100 meters or more.
For the first time, the dangerous effect of electromagnetic fields of power lines on the human body was discovered in the 60s of the last century. After careful studies of the health status of people who are in close contact with power lines in industrial conditions, scientists have discovered alarming facts. Almost all examined persons complained of increased fatigue, irritability, memory and sleep disorders.
To all of the above symptoms that occur in a person after frequent contact with electromagnetic waves of industrial frequency, one can safely add depression, migraine, disorientation in space, muscle weakness, problems with the cardiovascular system, hypotension, visual impairment, atrophy of color perception, decreased immunity, potency, changes in blood composition, etc. etc. The list can be continued with a number of physiological disorders and all kinds of diseases.
Very often, people living near power lines experience cancer, serious reproductive disorders, as well as the so-called electromagnetic hypersensitivity syndrome. It is rather scary to hear reports of studies by some foreign scientists on the impact of high-voltage power lines on the health of our children. For example, Swedish and Danish researchers found that children living up to 150 meters from power lines, substations and subways (!), are twice as likely to get leukemia, and almost every one of them has disorders of the nervous system.
In some countries, there is such a medical term as electromagnetic allergy. People suffering from it have the opportunity to change their place of residence to another, located as far as possible from sources of electromagnetic radiation. And all this is officially sponsored by the government! How do I comment on the power industry about the possible danger posed by power lines? First of all, they insist that the voltage of electric current in power lines can be different, and therefore one should distinguish between safe and dangerous voltage. The range of influence of the magnetic field created by the power line is directly proportional to the power of the line itself. A professional offhand determines the voltage class of power lines. You can also have this knowledge. Everything is quite simple - you need to pay attention to the number of wires in the bundle (not on the support itself). So: 2 wires - 330 kV 3 wires - 500 kV 4 wires - 750 kV The lower voltage class of the power transmission line is determined by the number of insulators: 3-5 insulators - 35 kV 6-8 insulators - 110 kV 15 insulators - 220 kV.
In order to protect the population from the harmful effects of power lines, there are special standards that define a certain sanitary zone, conditionally starting from the outermost wire of the power line projected onto the ground. So: Voltage less than 20 kV - 10 m, 35 kV - 15 m, 110 kV - 20 m, 150-220 kV - 25 m, 330 - 500 kV - 30 m, 750 kV - 40 m. The above standards apply for some reason specifically to Moscow and the Moscow region. Naturally, in accordance with them, building plots are also allocated. The most interesting thing is that these standards do not take into account the harmful effects of electromagnetic radiation, and in fact it is sometimes dozens, and sometimes hundreds of times more dangerous to health!
And now WARNING! So that the magnetic field does not affect your health, multiply each of the listed indicators by 10 ... It turns out that the smallest power transmission line is harmless only at a distance of 100 meters! The wires of power lines conceal a voltage that is in maximum contact with the threshold of a corona discharge. In bad weather, this discharge releases a cloud of oppositely charged ions into the atmosphere. The electric field created by them, even at a great distance from power lines, can be much larger than the permissible harmless values.
Quite recently, a new project of the Moscow government on the transfer of some sections of high-voltage power lines underground received a “green light”. The mayor's office plans to put the vacated area under construction. This is where a logical question arises - will underground power lines be safe for people living above them? Will developers call energy specialists to the area planned for housing construction? The electromagnetic radiation of underground power lines and its impact on the human body, unfortunately, is still poorly understood ...
The first to go underground will be power lines located in the districts - Leninsky Prospekt, Prospekt Mira and Schelkovskoye Highway. Further, it is planned to remove under the ground power lines of the North-Eastern Administrative District, namely in Northern and Southern Medvedkovo, as well as in Bibirevo and Altufyevo. These territories have already been put up for sale and are waiting for their investors. In total, there are more than a hundred power lines and open-type electrical substations in the capital. Potential developers of "power lines" lands, and with them the Moscow government, argue that modern technologies will completely isolate electromagnetic radiation. For this, it is planned to use coaxial cables laid in special shielded collectors.
Unfortunately, moving power lines underground is an expensive procedure (costing about 1 million euros per 1 km of cable being laid), and therefore there is no guarantee that developers will not "save". So no one knows whether housing built over power lines will become safe in all respects. Remember, if your house is located very close to power lines (see above for permissible sanitary standards), the most correct decision is to buy a new home located in a safer area!
In the 60s, specialists in Russia paid attention to the electromagnetic fields of power lines (TL). After lengthy and in-depth studies on the health of people who have contact with power lines at work, the results of these studies showed that people who were in the electromagnetic field for a long time often complained of weakness, irritability, fatigue, memory loss and sleep disturbance.
Currently, there are many problems associated with prolonged exposure to power lines on the nervous system, cardiovascular, immune and reproductive systems.
Power line(TL) - one of the components of the electrical network, a system of power equipment designed to transmit electricity through electric current.
The wires of a working power line create electric and magnetic fields of industrial frequency in the adjacent space. The distance to which these fields propagate from the wires of the line reaches tens of meters.
Within the sanitary protection zone of power lines it is prohibited:
place residential and public buildings and structures;
arrange areas for parking and stopping all types of transport;
to locate car service enterprises and warehouses for oil and oil products;
carry out operations with fuel, repair machines and mechanisms.

And now what is happening in reality:

One of the most powerful electromagnetic wave exciters is industrial frequency currents (50 Hz). So, the electric field strength directly under the power line can reach several thousand volts per meter soil, although due to the property of reducing the tension by the soil, already at a distance of 100 m from the line, the tension drops sharply to several tens of volts per meter.
Studies of the biological effects of the electric field found that already at a tension of 1 kV / m, it has an adverse effect on the human nervous system, which in turn leads to disorders of the endocrine apparatus and metabolism in the body (copper, zinc, iron and cobalt), disrupts physiological functions: heart rate, blood pressure, brain activity, metabolic processes and immune activity.
As for electricians and other power line workers, the situation is even worse.
The personnel of power transmission lines had visual impairments, changes in color perception, narrowing of visual fields in green, red and especially blue, vascular changes in the retina. Studies have been conducted of professionals working 8 hours a day in contact with AMY. Some have experienced a decrease in sex drive, a tendency to depression and irritability. There was a decrease in the number of lymphocytes in the blood.
See what happens to the biofield of a person living near power lines:
Human biofield- this is its electromagnetic field, that is, the totality of the radiation of each cell of our body. In fact, it is possessed by any object on Earth, any living organism.
Our electromagnetic field was formed under the influence of the Earth's electromagnetic field. And since today's electromagnetic background is tens of thousands of times higher than natural, our field cannot withstand such an onslaught.
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.
From an energetic point of view, the biofield performs a protective function. It is also called an aura. In fact, this is the first protective barrier.

Data:
One of the largest studies of this issue took place in England and Wales from 1962 to 1995.
Medical records of more than 29,000 children under 15 were reviewed
It turned out that the risk of leukemia in children who lived from birth at a distance of up to 200 meters from power lines is 70%, and from 200 to 600 m - 20%.
Statistical data showed that power lines have a significant negative impact.
“Our study shows that about 5 out of 400 cases of childhood leukemia can be associated with high-voltage lines, which is about 1% of cases,” said Gerald Draper, head of the research team at the University of Oxford.
The works of V. N. Anisimov cite the facts of Swedish scientists:
They analyzed data on the incidence of cancer among people living in close proximity to high-voltage power lines (at a distance less than 300 m).
In a group of 400 thousand. person was found 142 children with various types of malignant neoplasms and 548 adults with a brain tumor or leukemia.
Also, a survey was conducted on the subject of reproductive function in 542 workers substations power lines. This analysis revealed such pathologies as:
1) an increase in the number of congenital malformations if the father worked at a power plant;
2) decrease in the function of fertilization among a part of male workers
3) the birth rate of boys has decreased.Was also examined youth group under 18 living and within 150 m from substations, transformers, metro, railway power lines and power lines. They were twice as likely to have disorders of the nervous system and leukemia.
In Denmark, 1707 children under the age of 16 were examined during the period. Due to living near power lines, some have developed brain tumors, leukemia.
Protection against electromagnetic fields of power lines:
And what to do??
We understand that if a power line is built near your house, you cannot move it. And not everyone can afford to move today.
And even if you don’t live near power lines, then, believe me, they make a very good contribution to the general electromagnetic background of the city in which you live anyway.
Today, there is already a reliable protection against electromagnetic fields and their torsion components.
This must be done because the situation concerns your health and the health of your entire family. Especially if you are young and just planning it, or you have small children.
In the 1960s it was discovered dangerous exposure to electromagnetic fields of power lines on the human body.
The health status of people in close contact with power lines in production conditions or living nearby is approximately the same. People complain of increased fatigue, irritability, memory impairment, sleep disturbance, depression, migraine, disorientation in space, muscle weakness, problems with the cardiovascular system, hypotension, visual impairment, color perception atrophy, decreased immunity, potency, changes in blood composition. This list can be continued with a number of physiological disorders and all kinds of diseases.
It has been proven that people living near power lines have oncological diseases, serious reproductive disorders, as well as the so-called electromagnetic hypersensitivity syndrome. It is quite scary to hear reports of research by some foreign scientists on the impact of high-voltage power lines on children's health. It was found that children living at a distance of up to 150 meters from power lines, substations, are twice as likely to suffer from leukemia, and almost every one of them has disorders of the nervous system.

They talk a lot about the dangers of high-voltage power lines and most often in vain. Whatever theories have been put forward about how power lines affect a person, here the statistics of the incidence of cancer of people living in an area with a nearby high-voltage line, and the effect of power lines on brain cells, and even widespread hair loss are associated with closely spaced high-voltage lines. Let's try to understand this issue and justify what they say, but never prove.
So, only two types of radiation can come from power lines, in the form of a static field and variable waves. In addition to high-voltage lines, electrical wiring and any of the electrical appliances in our houses and apartments give the same radiation. For comparison, let's take one AC outlet with a voltage of 220-240 volts, located a meter from a person, and a power line with a voltage of about 200 kilovolts, located at a distance of 30 meters. The strength of the static field becomes less proportional to the square of the distance, so both sources of radiation, and the socket, and power lines have approximately the same effect.
In the case of alternating waves, the attenuation is much weaker, since their strength is inversely proportional to the distance from the radiation source, and if we take the same distances as in the previous case, then a power line with a voltage of 6 will become the equivalent of an outlet located a meter from us, 5 kilovolts. Please also pay attention to the fact that not one socket is installed in our housing, but also meters of electrical wiring, a refrigerator, a TV, a computer, a bunch of other electrical appliances, and their radiation will be much stronger.
It is impossible to say that high-voltage power lines have any detrimental effect on the human body. The fact is that this question has never been studied to the end. In theory, the only thing that a nearby power line can cause in the body is the resonance of internal organs. However, the industrial frequency of the current is 50 Hz, and there is no such frequency in the human body, lower frequencies have an effect on us. However, people who work with high voltage, including high-voltage power lines, have been noted that they have chronic fatigue syndrome, irritability, weakened immunity. It is quite possible that these symptoms are related to the fact that working with high stress requires constant composure and attentiveness, unlike other jobs, when increased attention is required only periodically.
The question of the dangers of power lines will remain unexplored for a very long time, and the point is not even that there are people for whom it is important that this information remain sealed, although this may well be the case, the point is that each person has a very different perception of both electromagnetic fields and static radiation from high-voltage lines. In some countries, there is even the concept of "electrical allergy".
People who are especially sensitive to the radiation of electrical appliances and high-voltage lines have the right to move to a longer distance from passing power lines. By the way, all costs and the search for housing incurs the government. In our country, the maximum that money was spent on was the development of norms according to which high-voltage lines are installed. Residential buildings should be located no closer than 10 meters for a line of 35 kilovolts, 50 meters for 110-220 kilovolts and 100 meters for 330 kilovolts and above. The distance is considered from the extreme wire to the wall of a residential building.
Another interesting fact, living next door in the same house, two people of the same age can experience different effects from a nearby power line. For one, it will act depressingly, while the other will, on the contrary, feel a surge of vigor and strength.
It turns out that really high-voltage power lines affect people differently. Perhaps this is what hinders the study of this area? Although it is quite possible that in reality there is no powerful influence at all, but in both the first and second cases it is just self-persuasion.
At the moment, there is no evidence of the harm of power lines to humans, however, nothing has been written about their harmlessness. Indeed, what is known for certain is that they have a certain effect on the human body, but how much it adversely affects us remains a mystery.
Nevertheless, supporters of the opinion that high-voltage lines destroy the human body annually publish dry numbers of mortality statistics in areas where powerful power lines pass. Sanitary services, in turn, argue that high-voltage power lines are harmless and provide physical calculations. If you look at this problem sensibly, without giving preference to one or the other side, then you can draw certain conclusions. For example, a drop of water cannot kill a person, but if it methodically drops on his head, then very soon the person goes crazy.
If you spend your whole life under a power transmission line of 330 kilovolts, then naturally there will be a very significant effect of its radiation on your body, but if you are constantly at a distance from power lines and only periodically come into contact with the radiation emitted by them, then you will not experience any changes in your body notice.
That is why, if possible, try to get out of the city, at least occasionally, because our cities have long become a kind of energy cesspools, where electromagnetic, static and many other types of energy fields are intertwined. Somewhere acting on each other, they weaken, somewhere overlapping, intensify many times and no longer meet sanitary standards. It is virtually impossible to protect yourself from them, but almost everyone can give their body a break from their effects.
