Summary

This article discussed an update to an earlier review of studies investigating the carcinogenic potential of magnetic fields in animal models bringing the total to more than 60 completed studies, mostly of ELF magnetic fields delivered either continuously or intermittently. Another study was reviewed which examined the potential promoting action of magnetic fields on induction of brain tumors by ionizing radiation. It is generally considered that extremely low frequency (ELF) EMFs do not possess enough energy to damage DNA directly, but there have been some reports in the literature of damage to DNA after exposure to ELF EMF, and some of these reports are presented and discussed. Recent studies of disturbances in pineal function and melatonin release in both rodents and non-rodent species have been inconsistent. Here we discuss a study of circadian rhythms in human male volunteers exposed or sham exposed to ELF EMF. Electrical hypersensitivity, the development of skin and other symptoms in association with exposure to electrical devices, especially video display terminals, has attracted significant research interest, and a recent article adding additional data and is reviewed here. The analgesic activity of EMFs in snails is discussed in detail and compared to a study in rodents. [five pages, 15 references].
