Summary

We review several papers attempting to clarify with the help of animal models the extent of any association between exposure to EMFs and development of childhood cancers. One group looked at exposure to Extremely low frequency (ELF) magnetic fields to see whether there was any effect on mammary tumor formation induced in female rats by a chemical carcinogen. We discuss their results and those of another research group who undertook to replicate their findings without success. A Russian group studied the effect of a 3-week course of modulated EMF on the growth of C-45 sarcoma in rats and came up with some very surprising results that we discuss in relation to the first two reports. A study by a group in Hannover, Germany, which examined the effects of acute and chronic exposure to 50-Hz magnetic fields on selected immune system parameters in female rats, is discussed. A review covers the problem of exposure to EMFs and reproductive failure, dealing in turn with ELF EMF, VDT emissions, mid-frequency radiofrequency (RF), microwave fields, occupational exposures, and medical exposures. We discuss a study concerning the effects on plasma and cerebrospinal fluid ionic composition of exposing cows to a power-line frequency field. [six pages, 12 references].
