Remote effects of occupational and non-occupational exposure to electromagnetic fields of power-line frequency

A retrospective cohort study of mortality in the personnel of power-supply plants in the European regions of Russia was carried out. Statistically non-significant raise of mortality from leukemia was found, compared to low mortality rates due to all other causes including cancer of any type. Standardized mortality ratio (SMR) was equal to 2.03. In the retrospective case-control study the haemoblastosis development risk under occupational power-line frequency (PF) EMF exposure was evaluated. In another retrospective case-control study the risk of the haemoblastosis development in children due to parents PF EMF occupational exposure was evaluated. The data of 208 cases and 319 controls interview showed that the odd ratio was 1.69. A retrospective cohort study of mortality in a settlement situated near a high-voltage (500 kV) substation, which took into account PF EMF levels in residential areas, revealed low mortality rates, except leukemia mortality. The obtained data do not allow excluding a possibility of PF EMF leukogenic effect.
