Spectral lines: Electromagnetic hazards

To the public´s worries about electric fields, microwave radiation, nuclear power, video terminals, and computer keyboards may be added a new concern — the effects of low-frequency electromagnetic fields. A study commissioned by the State of New York was interpreted by the state health official who administered the study, David Carpenter, as appearing to link exposure to electromagnetic fields with leukemia and other types of cancer in children. Carpenter is dean of the School of Public Health Sciences at the State University at Albany.
