The article aims to acquaint the public with the basic issues of the effects of the electromagnetic field on humans and their potential health risks. Since the beginning of the 20th century, many electrical and electronic devices have been used that have fundamentally changed their lifestyle. In addition, there has been an enormous increase in the use of wireless communication in the last twenty years than ever before - since the introduction of radio broadcasting in 1923 and television broadcasting in 1953, where there were several transmitters with a higher output of 10 to 1000 kW in Czechoslovakia, mostly located outside large cities. We currently use transmitters with outputs of 10 W to 70 W, in the number of about tens of thousands, and other transmitters with low outputs from 0.1 W to 1 W, which are in almost every household. Most of these radiation sources are still on and affect people around for 24 hours a day. Are we aware of what environment we live in when this radiation cannot be seen or heard? What are its effects on the human body? Man is exposed to natural sources of electromagnetic fields (the earth's electromagnetic field, cosmic rays, electrostatic discharges in the atmosphere, the solar wind and various others) throughout his life. With the scientific and technical development, artificial sources of electromagnetic radiation have been added, such as radio and television transmitters, but also base stations for mobile operators, mobile and wireless communication, detection devices at airports, or security systems in shops. Artificial sources of electromagnetic fields can cause thermal and non-thermal biological effects on living organisms. Part of the paper is an exploratory survey on the issue. Survey aimed at that issue is part of the contribution.
