In this paper are present the results of measurements of magnetic induction at some locations
in city Bor (the east Serbia) dating from the household electric devices and transformer stations suited near the residental areas. Stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. Risk of the extremely low frequent electromagnetic radiation of frequency 50 Hz on human health, by measuring the magnetic induction, is considered. The measured data are compared with the corresponding ones in literature, as well as with the critical values suggested by the Serbian Ministery of Environment, Mining and Spatial Planning. It is shown that some of them produce a very strong electromagnetic field, so that people should stay far from them. The necessity to relocate the transformer stations to the safe distance from residental areas, as well as the regular control of the positions of the household electrical equipments in the residental places, are strongly recommended.
