In modern human life, almost any electrical device has its own radiation. The source of the electromagnetic field (EMF) is a high-voltage line, a TV, and even a personal smartphone. All of humanity lives in one big place, this is the Earth, which is initially penetrated by natural waves of a different spectrum.
Common space
Scientists have established the level of the natural wave background in which the body is accustomed to exist. The globe has two distinct poles, and every day we experience the influence of the radiation spectrum. Changing under the influence of external factors, the electromagnetic field of a person is disturbed, which leads to health problems.
Researchers have long noticed that the largest wars in the world occurred after solar flares when the Earth’s natural magnetic background was disturbed. Recently, this indicator is given in weather forecasts on television. In nature, there are special places with rocks. Here a person cannot be for the following reason: electromagnetic radiation and the electromagnetic field of one's own do not coincide.
Health effects
Electromagnetic radiation and electromagnetic field affect human health, therefore, acceptable indicators were established. The negative effect of waves on the nervous system, the work of the brain and heart was noted. In animals and insects living in areas of increased EMF, pathologies in the structure of the body are observed.
According to studies, the influence of waves negatively affects the well-being of a person. Headache and fatigue are provoked, the work of internal organs is disrupted. The older generation may even lose consciousness in the danger zone: near high-voltage lines or a working electromagnet.
The source of the electromagnetic field is:
- Cellular communications, smartphones, Wi-Fi emitters, household appliances. Strong EMF appears when the microwave works.
- Electric transport, conducting highways, industrial facilities.
- Radars, walkie-talkies, radiating installations.
- Medical scanners, metal detectors, frames at airports.
- Telecommunication, UHF installations.
Norms
A sanitary zone should be organized next to powerful emitters according to regulatory enactments. It is calculated according to the technical data of the facility by a special commission. Standard values are indicated in the documentation. So, when forming indicators, the network voltage and the current flowing through the wires are taken into account.
Such a source of electromagnetic field is a high-voltage power line that feeds the whole city. The sanitary zone takes into account that the load on suitable wires varies with the time of day and year. The area of this site is dangerous for people, animals and plants. The maximum permissible limit that is not dangerous for the body is the magnetic flux density of 0.3 μT. Above this value, a healthy person can manifest oncological and heart diseases.
Home appliances
The source of the electromagnetic field is a personal computer, a refrigerator and any other household appliance. Manufacturers of equipment take into account the problem of the occurrence of spurious EMF and make improvements to the design of products. Home-made devices can be dangerous for cores and people suffering from psychological disorders.
Therefore, the instructions in the microwave oven indicate: it is not recommended to be directly in front of the front panel while heating food. A prolonged stay of pregnant women in an area of high electromagnetic field can lead to miscarriages. Scientists have proven the fact that a cell phone affects the well-being of a person. It is better not to leave it near the head for the night and not carry it in pockets near the heart.
Outside
The source of the electromagnetic field is power lines, electric vehicles: trams, trolleybuses. Therefore, when choosing a suburban area, experienced people try to stay away from lines with high-voltage wires, broadcasting stations, cell-phone repeaters, and electrical substations. If you suspect that the permissible limits are exceeded, the radiation can be checked by the device. The culprit will be required to eliminate the negative factor.
Another powerful emitter is the railway. Near her, there will certainly be overstated indicators. However, you can’t get away from them, this is a fee for the convenience of the citizens.
Methods of struggle
One of the main ways to exclude the influence of EMF on a person is the spatial distance of radiating objects. High-voltage lines are laid high above natural landscapes, so as not to harm plants and animals. It is forbidden to erect residential buildings, grow crops, and graze livestock near such structures.
Shielding of radiating objects is common in the city. The energy of the electromagnetic field does not penetrate through grounded metal shells. If a person is isolated for a long time from the field of the Earth, he will have severe weakness or, conversely, aggression. A similar state of health manifests itself in sailors or submariners after a long voyage.
Wave treatment
With proper radiation, the opposite effect can be observed. It is used in medicine to restore body functions. The source of the electromagnetic field is a permanent magnet, which the patient applies to the sore spot. Long-term therapy relieves chronic ailments of joints, blood vessels, and heart.
EMF is used to relieve pain, improve blood circulation, and fatigue quickly passes through it. The therapeutic effect is formed due to the ionization of the metal constituents of the blood. A person feels the warming effect of radiation. Periodic use of medical devices negates relapses of chronic diseases.
The electromagnetic field positively affects immunity, removes edema. Rapid cell regeneration after injuries is observed. However, magnetotherapy can have a negative effect in the presence of pacemakers or when a person has a blood disease. The doctor should prescribe such treatment according to the results of the examination.
What else is forbidden to place in negative zones?
The sanitary zone near strong sources of the electromagnetic field is established by supervisory authorities. In this place, all objects are placed only after agreement with them. The ban applies to premises and sites reserved for the storage of fuels and lubricants. It is impossible to build oil depots, gas stations, parking for any type of transport, except electric.
Also, no people should be in the zone. It is forbidden to place stops, markets, arrange meetings. If it is necessary to organize such places, source shielding is used. On the roofs where there are transmitting stations, you can often see a metal mesh around the antenna. So achieve a narrowing of the sanitary zone.
Similar measures are taken to protect residential and industrial buildings from conventional and ball lightning. A metal antenna is installed on the roof, grounded deep in the ground. Around the building, an accumulation of positive potential is formed, and the electrons leave the artificial chain. When placing a new device in your house, it is better to take care in advance about the place of its installation away from the sleeping room.
