Model		electrical and electronics workers occupationally exposed to microwaves and brain tumor incidence
Details		Human subjects (electrical and electronics workers in northern New Jersey; Philadelphia, PA & surrounding counties; and the gulf coast of Louisiana) who died of brain tumors (435 cases vs 386 matched controls) were examined for previous EMF exposure history, including exposure to RF, via interviews with study subjects' next of kin or by classification of jobs by a certified industrial hygienist who assigned codes for presumed exposure to RF, lead, and soldering fumes. The results of both previous exposure history assessments indicated a significant risk of brain tumors with RF (OR = 4.6, 95% CI 1.9 - 12.2), with risk increasing with duration of exposure of over 5 years. The authors conclude that, while an increase in brain tumors is associated with increased microwave exposure, the specific etiologic agent cannot be identified from these data because these jobs also involve exposure to soldering fumes and organic solvents.
