In modern human life, almost any electrical device has its own radiation. The source of the electromagnetic field (EMF) is a high-voltage line, TV and even a personal smartphone. All mankind lives in one big place, this is the Earth, which was initially penetrated by natural waves of various spectrums.
Shared space
Scientists have established the level of natural wave background in which the body is accustomed to exist. The globe has two different poles, and every day we experience the influence of the radiation spectrum on ourselves. Changing under the influence of external factors, the electromagnetic field of a person is disturbed, which leads to he alth problems.
Researchers have long noticed that the biggest wars in the world took place after solar flares, when the Earth's natural magnetic background was disrupted. Recently, this indicator is given in weather forecasts on television. In nature, there are special places with rocks. Here a person cannot be on the followingreason: electromagnetic radiation and electromagnetic field do not match.
He alth effects
Electromagnetic radiation and electromagnetic field affect human he alth, therefore, acceptable indicators have been established. The negative effect of waves on the nervous system, the work of the brain and heart was noted. Animals and insects living in areas of increased EMF are observed to have pathologies in the structure of the body.
According to research, the influence of waves has a negative impact on a person's well-being. Headache and fatigue are provoked, the work of internal organs is disrupted. The older generation can even pass out in a dangerous area: 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 occurs when the microwave oven is operating.
- Electric transport, transmission lines, industrial facilities.
- Radars, walkie-talkies, radiating installations.
- Medical scanners, metal detectors, airport frames.
- Telecommunications, UHF installations.
Norms
A sanitary zone should be organized next to powerful emitters according to regulations. It is calculated according to the technical data of the object by a special commission. Standard values are specified in the documentation. So, when forming indicators, the mains voltage and the current flowing through the wires are taken into account.
This 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 allowable limit, which is not dangerous for the body, is the magnetic induction flux density, equal to 0.3 μT. Above this value, a he althy person may develop cancer and heart disease.
Home Appliances
The source of the electromagnetic field is a personal computer, refrigerator and any other household appliance. Manufacturers of equipment take into account the problem of the occurrence of parasitic EMF and make improvements to the design of their products. Homemade devices can pose a risk to hearts and people suffering from psychological disorders.
Therefore, the microwave oven instructions indicate: it is not recommended to be directly in front of the front panel while heating food. Prolonged stay of pregnant women in the zone of increased electromagnetic field can lead to miscarriages. Scientists have proven the fact that a cell phone affects a person's well-being. It is better not to leave it near the head at night and not to carry it in pockets near the heart.
Outdoor
The source of the electromagnetic field is power lines, electric transport: trams, trolleybuses. Therefore, when choosing a suburban area, experienced people try to stay away from lines with high-voltage supplywires, broadcasting stations, cellular repeaters, electrical substations. If you suspect that the permissible limits are exceeded, the radiation can be checked with a device. The culprit will be obliged to eliminate the negative factor.
Another powerful emitter is the railway. Near it, there will definitely be inflated indicators. However, there is no getting away from them, this is a price for the convenience of the citizens' movement.
Methods of struggle
One of the main ways to eliminate 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 build residential buildings, grow crops, and graze livestock near such structures.
Shielding of emitting objects is widespread in the city. The energy of the electromagnetic field does not penetrate through grounded metal shells. If a person is isolated from the Earth's field for a long time, he will have a strong weakness or, conversely, aggression. A similar state of he alth is manifested in sailors or submariners after a long voyage.
Wave Treatment
With the right 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 the joints, blood vessels, heart.
EMF is used to relieve pain, improve blood circulation, and thanks to it, fatigue quickly disappears. The therapeutic effect is formed due to the ionization of the metal components of the blood. A person feels the warming effect of radiation. Periodic use of medical devices negates the recurrence of chronic diseases.
Electromagnetic field has a positive effect on immunity, removes swelling. There is a rapid regeneration of cells after injury. However, magnetic therapy can have a negative effect in the presence of pacemakers or when a person has blood diseases. The doctor should prescribe such treatment based on the results of the examination.
What else is forbidden to place in negative zones?
A sanitary zone near strong sources of an 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 areas reserved for the storage of fuels and lubricants. You can not build oil depots, gas stations, parking lots for any type of transport, except for electric.
Also, people should not be in the zone. It is forbidden to place stops, markets, arrange meetings. If it is necessary to organize such places, shielding of the source is used. On rooftops where there are transmitting stations, you can often see a metal mesh around the antenna. This is how they achieve narrowing of the sanitary zone.
Such measures are being taken to protect residential and industrialbuildings from ordinary and ball lightning. A metal antenna is installed on the roof, grounded deep into the ground. An accumulation of positive potential is formed around the building, and the electrons go through an artificial circuit. When placing a new device in your home, it is better to take care in advance about the place of its installation away from the bedroom.
