The
authors studied 435 men who died from brain cancer in
three areas of the USA. These men were matched with
controls who died of other causes. Information on occupation
and other relevant factors was obtained from interviews
with next-of-kin. Occupational exposures
were assessed in two ways - by comparison with a known
list of exposed occupations, and by individual assessment
by an industrial hygienist. There was an excess risk
(odds ratio
2.3) of brain tumor death in men ever employed in an
electrical or electronic occupation, but not in those
exposed to RF radiation who did not work in an electrical
job (odds ratio 1.0). It appeared that the increased
association
in electrical workers was likely to be due to an exposure
other than RF radiation.
