Interaction of extremely-low-frequency electromagnetic fields with living systems

The sources and physical properties of extremely-low-frequency (ELF) electromagnetic fields are described. Biological effects and mechanisms through which ELF fields interact with humans and other organisms are discussed, including several aspects of this subject that are under active laboratory investigation. Studies on the potential health effects of ELF fields present in the home and workplace are also summarized, including a critical evaluation of evidence for a possible linkage between exposure to ELF fields and cancer risk
