Protection of a person from electromagnetic fields is currently a necessary direction to protect his health. After all, this phenomenon accompanies the city dweller everywhere in connection with the rapid development of radio communications and television, mobile cellular communications, as well as the Internet. All these achievements of scientific thought penetrate more and more into our lives and “pollute” the environment.
Protection against electromagnetic fields and radiation is also required when using household electrical appliances, computers and urban electric vehicles. Unfortunately, few people realize the degree of this danger. First of all, the radiation intensity is subject to assessment. And the electromagnetic fields created by irons, telephones, refrigerators and other devices we need are extremely small. However, a person must protect his health in this case too. After all, the situation is much more complicated than we think, and the consequences are extremely dangerous. This circumstance convinces us that each of us should have an idea about electromagnetic fields harmful to his health, correctly assess the existing degree of danger, and use all necessary means and methods of protection.
Artificial fields
What is electromagnetic radiation or wave? This is nothing more than a stream of moving charged particles that occurs in an electromagnetic field (EMF). Such radiation is not an analog of radiation and does not cause ionization in its path. However, this fact does not mean at all that we do not need protection from electromagnetic fields and radiation. The fact is that this phenomenon spreads over long distances and can negatively affect the human body.
Health effects
Today we are surrounded by the electromagnetic world. It is full of all the benefits of civilization, which we simply cannot refuse. However, the natural mechanism by which protection against the action of EMF would be implemented in humans is absent.
Being essentially open systems, all living organisms interact informatively with external radiation. Over the past five decades, we have literally been surrounded by artificial electromagnetic fields, which basically replaced the subtle elusive energies of the natural world. Around the clock, a person literally bathes in invisible streams of particles that are emitted by power lines, computers, televisions and a variety of electronic devices. In addition, waves of television and radio transmitters, as well as signals emitted by cellular telephone communications, attack us.
The chaotic energy of particles arising at the same time is a kind of electromagnetic dirt. It has a tremendous destructive force acting on the bioelectric field of the human body, and yet in it the balance between millions of elusive electrical impulses we must normally maintain. This balance regulates the activity of each cell. The stronger the effect of artificial electromagnetic sources, the greater the disturbance caused in the human biofield. This negatively affects the body.
Possible pathologies
According to scientists, the current electromagnetic radiation is 100 million times higher than that experienced by our grandfathers and grandmothers. With prolonged exposure to charged particle flows, it can seriously impair our health. Thus, according to epidemiologists, those who live close to powerful sources of electromagnetic fields most often suffer from cancer. These, for example, are high voltage power lines.
The negative effect of charged particles on the production of a hormone such as melatonin has also been proven. It is produced by the pineal gland and plays a significant role in strengthening the immune system. Sometimes this element is called the "hormone of youth."
When exposed to external sources of electromagnetic radiation, a person may encounter problems such as:
- depression and insomnia, memory impairment and headaches, dizziness and muscle weakness;
- malfunctions of the heart and blood vessels, expressed in instability of the heart rhythm, neurocirculatory dystonia, hypertension and disorders in the blood;
- depression of immunity;
- endocrine dysfunction;
- disorders in the reproductive system, expressed by deterioration of spermatogenesis, slowed fetal development, various complications of pregnancy, etc.
- imbalance of the energy system and its pathogenic changes.
Existing Norms
The probability of such dangerous consequences indicates that protection from the electromagnetic field and the radiation it causes is a necessity for the human body.
One of the security measures against this phenomenon in our country are strict standards, which are reflected in SanPiN 2.2.4.1191-03. They indicate the limit levels that electromagnetic radiation should have in the workplace and in the workplace. There are sanitary and epidemiological standards and regulations, as well as hygiene standards. They are called, respectively, GDR (PDU) 5803-91 and DNAP 0.03-3.22-91.
The maximum permissible dose of electromagnetic radiation that a person can receive without harming his health is considered to be 0.2 μT.
The most powerful sources of EMF
Urban residents suffer from a sufficiently high level of radiation that is generated by electric vehicles. What are the methods of protection against electromagnetic fields of this type? They are considered in special norms and GOSTs, establishing a reduction in the harmful effects of the flow of charged particles on the population. These documents provide distance protection. In other words, for the safety of the population, sanitary zones are being created around tram and trolleybus trolleys, electric train and metro lines. The same protective measures must be observed in the vicinity of standing power lines. Moreover, the width of such a sanitary zone will depend on the power of the transmission line.
Strong emitters of electromagnetic fields are television and radio broadcasting stations. Sometimes they are located directly in the residential area. What should be the protection against the electromagnetic field of these stations? The basic principle of ensuring safety in this case is the observance of the levels of electromagnetic fields, the maximum permissible values of which are indicated in the legislatively established sanitary norms and rules.
Wiring
This source of electromagnetic radiation is among the most common. After all, electrical wiring is present in any home in the form of cable lines that carry electricity, as well as switchboards and transformers. This integral component of people's livelihoods makes the biggest contribution to the deterioration of the electromagnetic environment of residential premises.
How to protect yourself from the effects of electrical wiring?
In this case, only preventative measures can be used. They include:
- the exclusion of the possibility of a long stay in a room where there is an increased level of magnetic field;
- such an arrangement of furniture for rest, which provides for its placement no closer than two to three meters from the location of power cables and distribution boards;
- the choice of a system with a lower level of magnetic field, which provides underfloor heating;
- maximum removal of the recreation area from electrical cabinets and unknown cables in the room.
Household Appliances
As already mentioned above, all electrical devices that are indispensable assistants in our home are sources of EMF. The most powerful of them are electric and microwave ovens, hoods and washing machines, vacuum cleaners, as well as refrigerators equipped with the No frost system. The magnitude of the fields emitted by them depends on the particular model. However, it should be borne in mind that the higher the power of the device, the higher the electromagnetic field created by it. The value of the electric field in operating household appliances is significantly less than its maximum permissible values. It should be borne in mind that the largest EMF occurs in microwave ovens.
Measures to reduce the impact of household appliances
What are the methods of protection against electromagnetic fields generated by home devices? They are as follows:
- when choosing a device, keep in mind that its passport must contain notes on compliance with the requirements of special interstate sanitary standards;
- buy devices with low power;
- relax in the house at a fairly remote distance from refrigerators with No frost system, heaters, televisions, power supplies and chargers;
- Keep electrical appliances away from each other.
Means intended for cellular communication
The most urgent today is the question of what should be the protection against the action of electromagnetic fields created by gadgets. Long and serious studies have been carried out in this area. But to date, a definite answer to this question has not been found. Doctors note only the fact that for the entire period of using cellular communications, no one has received significant damage from their health.
To provide this new type of information transmission source, radio transmitting base stations and mobile phones belonging to subscribers operate.
Transmitting and receiving antennas are not classified as EMF sources. And this is due to technological requirements that must be observed when building the entire system that provides cellular communications. It implies the creation of such a radiation pattern of antennas, in which the main radiation energy is allocated not only to the side of structures located in close proximity, but also above them. Without these conditions, the normal functioning of the system becomes simply impossible. The specific effect of cell phones on the human body has not yet been fully elucidated, but the fact that our biofield “responds” to the radiation they create is a confirmed fact.
Mobile Security
Protection against the electromagnetic field generated by a mobile phone consists in the following recommendations:
- use of the gadget only when necessary;
- conducting continuous conversations only for three to four minutes;
- a ban on children using a cell phone;
- use in the car interior hands-free kit.
Personal computers
Protection against electromagnetic and electric fields created by these gadgets is especially relevant in our time. After all, personal computers have entered the lives of almost every one of us. Moreover, people use them not only at work. Many spend on luminous monitors and most of their free time.
The influence of a computer on a person, without any doubt, negatively affects his vision, general health, as well as the work of various organs and systems. However, the magnitude of this effect consists of many factors. They include ergonomics of the workplace, noisiness and illumination of the room, the quality of all PC devices and the EMF created by them.
Protection from the electromagnetic field of a personal computer is required, first of all, in connection with the exposure of the monitor to the cathode ray tube. If you compare all other PC devices with it, then their radiation is minimal. The only exception is the uninterruptible power supply.
PC security precautions
If a few years ago, to eliminate the negative impact of the monitor, such means of protection against electromagnetic fields as special screens were used, today there is practically no need for them. The fact is that thanks to modern technology, liquid crystal monitors were offered to users. In terms of their technical parameters, as well as in terms of the impact on our health, they have significant differences from the above for the better.
Those who continue to use monitors on an electronic tube should be aware that in their latest models, means of protection against electromagnetic fields in the form of a special screen are mounted directly into the case. Nevertheless, when working with a PC, you should adhere to some recommendations. They provide for:
- placing the monitor case on the electronic tube so that its back panel, which is the area of greatest radiation, is directed away from the user and people who are in close proximity to the workplace;
- creating sufficient illumination of the workplace, for example, using a fluorescent lamp;
- the need for short breaks in work.
