LEUKEMIA RISK AND OCCUPATIONAL ELECTRIC-FIELD EXPOSURE IN LOS-ANGELES-COUNTY, CALIFORNIA

The authors analyzed data on electric fields from a prior study of occ upational magnetic field exposure and leukemia risk conducted in Los A ngeles County, California, in 1972-1990. Ranking of exposure differed somewhat for magnetic and electric fields. The odds ratios were 1.22 ( 95% confidence interval (CI) 0.80-1.86) and 1.15 (95% confidence inter val 0.78-1.72) for medium and high exposure categories, respectively, and there was no clear evidence of an exposure-response relation (odds ratio for 10 V/m increase = 1.05, 95% CI 0.95-1.16). Although not con clusive, our analyses provide little support for an association betwee n occupational electric field exposure and leukemia.
