title: Analysis of exposure to electromagnetic fields during professional use of radiotelephones.
abstract: An environmental survey on exposure to EM fields covered over 300 radiotelephone operating in the range of 300-344 MHz with input power of 5 W, used by 574 radiooperators and 48 radiomechanics employed in sanitary transport, power engineering, municipal traffic and coal mining. The intensity of EM fields was measured and timing of effective radiotelephone transmitter work was done. According to the Polish standards, it was found that 3% of the population examined were subject to excessive exposure, 6%--to conditionally admissible only and 17%--to admissible. Exposure assessment, made for extreme conditions based on literature, theoretical and experimental data, showed that in radiomechanics' necks, eyes and wrists there may occur SAR values: 10-15 W/kg, 1-1.5 W/kg and 1.8 W/kg, respectively.
