[A methodological approach to studying the values of 50-Hz electromagnetic fields that influence the workers of power...

The necessity of studying the impact of electromagnetic fields (EMF) on the health status of the operation staff from power enterprises has stemmed from the improper prior significance being attached to this matter. The subjects of the investigations were operators' premises, work environment system, and operation staff. The intensity of the electrical and magnetic constituents of a 50-Hz EMF in the operation staff's workplaces, in the areas adjacent to 500- and 110-kVsubstation grounding systems, and in the flats of the approximate apartment houses where the workers lived was measured. Then their permissible cumulative daily exposure was calculated. Working arrangement was also assessed. The examinees' behavior was predicted in stress situations. This permitted a scientific rationale to be provided for protective measures against exposure to electromagnetic irradiations in productive and nonproductive conditions.
