Human exposure to the effects of the electromagnetic field is not a new problem. However the rapid and uncontrolled increase of electrical energy usage in the 20th century coupled with the growth in field of electronics, telecommunication, IT and satellite navigation as well as diagnostic and industrial devices brought us not only to analyze the civilisation dangers but also to come out with methods to screen the electromagnetic radiation.
The alarming American publication implies that the 'electromagnetic smog' is a cause of many civilisation illnesses such as circulation diseases, cancer, and diabetes and affects us much more than the changes in our lifestyle change.
[S.Milham, Medical Hypotheses 74(2010)337, Historical evidence that electrification caused the 20th century epidemic of "diseases of civilisation"]The negative impact that the electromagnetic radiation (EMR) has on a human body is mainly the fact that it interferes with its basic vital functions. The electrical currents in the human body are one of the normal vital functions. The nerve signals are based on electric impulses; many biochemical reactions such as digestion or brain activity are a result of electric processes.
It is not a surprise that a long-term exposure to electric fields, even of a small strength, can make us feel unwell.

During the last three decades the interest in the negative biological impact of the electrical, magnetic and electromagnetic fields has raised amongst the scientists and the international organizations (World Health Organisation, International Commission on Non-Ionizing Radiation Protection), that's when the need for screening arouse.
