RT Journal Article SR Electronic T1 Risk for leukaemia and brain and breast cancer among Danish utility workers: a second follow-up JF Occupational and Environmental Medicine JO Occup Environ Med FD BMJ Publishing Group Ltd SP 782 OP 784 DO 10.1136/oem.2006.029116 VO 64 IS 11 A1 Christoffer Johansen A1 Ole Raaschou Nielsen A1 Jrgen H Olsen A1 Joachim Schz YR 2007 UL http://oem.bmj.com/content/64/11/782.abstract AB Objective: To update a study of risks for leukaemia, brain cancer and breast cancer in a Danish nationwide, population-based cohort of utility employees. Methods: A multivariate statistical model including information on age, duration of employment, date of first employment and level of occupational exposure to electromagnetic fields was applied. Results: No increased risk for these cancers was seen among 28224 subjects with more than 3 months of employment in whom cancer had not been diagnosed before first employment. Conclusion: The results do not support the hypothesis of an association between occupational exposure to magnetic fields in the electric utility industry and risks for leukaemia, brain cancer and breast cancer.
