[Biological effects and health risks of electromagnetic fields at levels classified by INCRIP ans admissible among occupationally exposed workers: a study of the Nofer Institute of Occupational Medicine, Lodz].
The aim of the study was to evaluate the effect of electromagnetic fields (EMF) on the workers' circulatory system, and to find out to what extent the EMF frequency, short-term (maximum values) and chronic (daily and lifetime doses) exposures influence the type of the observed disorders. The gathered data will help to evaluate whether hygiene standards that limit maximum admissible EMF values (e.g., ICNIRP standards) protect against adverse effects of exposure. The study covered workers employed in transformer and distribution stations, medium wave transmitting stations, radio-service and radio and TV multichannel broadcasting stations. In all the cases, exposure levels were considerably lower than those set as admissible according to the ICNIRP standards. Nevertheless changes in the circulatory system and a significant relationship between blood pressure and neurovegetative regulation disorders and exposure parameters were observed. The frequency of changes in the circulatory system was significantly dependent not only on the maximum EMF value, but also on its dose, which indicates that the hygiene standards for EMF cannot be limited only to short-term exposure maximum values, but they should be supplemented with dose-related standards.
