Title Low-frequency electromagnetic fields around heating inductors
Original title Lågfrekventa elektromagnetiska fält kring några induktionsvärmare [in Swedish]
Bibliographic information Undersökningsrapport 1978:38, Arbetarskyddsstyrelsen, Fack, 100 26 Stockholm, Sweden, 1978. 21p. Illus. 33 ref.
Abstract Results are reported of measurements on induction-heated tools used for brazing, forging and quenching, to determine the intensity of the electric and magnetic fields (frequencies 3,830 and 10,320Hz) around the inductors. A literature survey gives details of the biological effects of low-frequency electromagnetic fields (fatigue, headache, reduced arterial blood pressure and white blood cell counts, magnetophosphenes, etc.). While a limit of exposure to these electromagnetic fields cannot be established, measures must be taken to reduce exposure to a minimum, especially in the case of high-frequency induction current.
