Biological effects of extremely low-frequency electromagnetic fields: in vivo studies.

This paper discusses the biological effects of exposure to extremely low frequency electromagnetic fields observed in animal studies. Three areas of investigation are reported: (1) studies on the nervous system, including behavior and neuroendocrine function; (2) experiments on cancer development in animals; and (3) measurements of currents and electric fields induced in animal models by exposure to external magnetic fields. An attempt is made to evaluate experimental results and interpret them with respect to potential health implications.
