There is growing interest and concern about the effect of weak, low-frequency electromagnetic fields on biological systems, with obvious implications for human health. In particular, it has been suggested that the incidence of childhood cancers might be increased by exposure, in the domestic environment, to low-frequency magnetic fields - indeed, there are several studies which seem to indicate that both children and adults living in homes near power lines or other
electric transmission facilities have an increased risk of cancer.

This book arises from an international workshop held under the auspices of the Environment Committee of the Royal Swedish Academy of Sciences, and many of the contributors are leading authorities in their subjects. It provides a well-balanced overview of the experimental and theoretical work which lies behind the `cyclotron resonance' hypothesis, places it in the context of other evidence and theories, and indicates its relevance to the possible cancer risk from electromagnetic
fields.
