EVALUATION OF ELECTROMAGNETIC FIELD EXPOSURE OF GENERAL PUBLIC AROUND TELECOMMUNICATION SOURCES

The exposure to radiofrequency electromagnetic fields (RF EMF) in the living environment is due to variety of sources, predominantly for telecommunications – radio and TV stations and base stations for mobile communication emitting in the frequency range from 100 kHz to several GHz. In recent years research has shown that such systems have significantly increased RF EMF levels in urban areas compared to those measured in the 1980s, when the major sources in the environment were analogue radio and television stations. The aim of the report is to present the assessment of electromagnetic field exposure to the general public from telecommunication sources on the territory of the country. Separate data from measurement and exposure assessment of RF EMF levels around base stations for mobile communication and Radio and TV stations are considered. The data contain results of spot measurements of RF EMF levels emitted by separate base stations for mobile communication and radio and TV stations and spot measurements in areas with a high density of RF EMF sources – 105 regions in the country. It covers 1376 base stations and 280 radio and TV stations. The received results show that RF EMF levels are below the permissible levels according to the national legislation. Higher values, within the exposure limits, are found in areas with large number of sources or when the emitters are mounted on small height, but in such cases the values are less than 30% of those in national legislation. Compared to the European legislation the registered RF EMF levels are below 1 % of exposure limits. The measured values of the electric field strengths and power densities around the radio and television stations are within the exposure limits according to the national legislation. Values above exposure limits have been found in 1-2% of cases, but they were measured outside the urban areas where only incidental stay of the general public is possible. In comparison to the European legislation (Council Recommendation 1999/519/ЕС) measured values of the electric field strength and power density around radio and TV stations are well below the limit values.
