Title Magnetic fields of high voltage power lines and risk of cancer in Finnish adults: Nationwide cohort study
Bibliographic information Oct. 1996, Vol.313, No.7064, p.1047-1051. 42 ref.
Abstract In this nationwide cohort study, 383,700 Finnish adults were identified by record linkages of nationwide registers. They all lived at some time during 1970-89 within 500m of overhead power lines of 110-400kV in a 50Hz magnetic field, calculated to be greater than or equal to 0.01ÁT. The numbers of observed and expected cases of cancer, standardized incidence ratios, and incidence rate ratios adjusted for sex, age, calendar year, and social class were assessed. Altogether 8415 cases of cancer were observed. All incidence rate ratios for both sexes combined were non-significant and between 0.91 and 1.11. Significant excesses were observed for multiple myeloma in men and colon cancer in women. The role of extremely low frequency magnetic fields in the pathogenesis of these tumours remains uncertain and the previously suggested associations between magnetic fields and other selected tumours were not confirmed.
