In both living and working environment, apart from the ever present Earth's atmospheric and magnetic fields, very often there is an existing very low- frequency electromagnetic field emitted by energy plants, home, radio and TV appliances, public transport vehicles and video terminals. Low-frequency electromagnetic fields (30-300 Hz) are also present in the vicinity of high-voltage transmission lines, high and middle voltage conductors, sub-stations and industry. A large number of people who work on servicing of these plants and devices are exposed to electromagnetic fields. To a certain degree even the tenants who live and even occupy the space near high-voltage transmission lines and converters for a certain period of time as well as those who use electric home appliances in their homes are exposed to the aforementioned.
Taking into consideration the recent results obtained from contemporary epidemiological examinations, the impact of these low-frequency magnetic fields are to a large degree undesirable and damaging to health. As a result, a warning has been issued about the frequent occurrence of malignant diseases, psychological disorders, genetic material damage, cardiovascular, nervous, hematopoetic system, metabolism and the occurrence of miscarriages in the exposed population.
Correspondingly, there is a growing need for further research of biological effects of such radiation with an aim to bring forth both unified standards as well as legal regulation that would regulate maximum allowed time of exposure by which both duration of stay in places with higher radiation and building of new industrial plants and tenements will be determined.
