Epidemiological Studies of Occupational EMF Exposures

by Robert B. Goldberg, Ph.D., Editor

Summary

In this issue we reviewed a number of studies that examined the risk of cancer among women in relation to occupation. They included a study of all actively employed Finnish women, about 20% of whom were exposed to extremely low frequency magnetic fields in their jobs, an analysis of registered cancers of the pleura, bladder, stomach, lung, and breast in women in England from 1971 to 1990, and a Chinese study comparing cancer risk to men and women electricians. Reanalyses of previously published studies frequently appear in the research literature. Here we present a reanalysis of EMF-related cancer risks in a large international utility industry study involving over 220,000 workers at 3 companies that now considered cumulative electric and magnetic field exposures together. The association of leukemia risk with electric- and magnetic-field exposure in Canadian electric utility workers was presented in another paper with emphasis on exposure metrics and possible confounders. Results of a meta-analysis of studies examining prostate cancer, melanoma, and brain cancer risk among flight personnel for the period 1986 through 1998 was discussed. Suicide among utility workers was also discussed. [three pages, 13 references].
