Title Association between exposure to pulsed electromagnetic fields and cancer in electric utility workers in Quebec, Canada, and France
Bibliographic information 1 Nov. 1994, Vol.140, No.9, p.805-820. 18 ref.
Abstract The authors report the association between exposure to pulsed electromagnetic fields (PEMFs) and cancer in electric utility workers in Quebec, Canada (follow-up, 1970-1988), and France (follow-up, 1978-1989), among whom 2,679 cases of cancer were identified. Exposures were assessed through a job-exposure matrix based on about 1,000 person-weeks of measurements from exposure meters worn by workers. Exposures were considerably higher in Quebec than in France. No association was found between PEMFs and cancers previously suspected of association with magnetic fields (leukaemia, other haematopoietic cancers, brain cancer or melanoma). However, there was a clear association between cumulative exposure to PEMFs and lung cancer, with odds ratios rising to 3.11 (95% confidence interval (CI) 1.60-6.04) in the highest exposure group (84 cases). The association was not explained by smoking or other occupational exposures.
