There is no convincing evidence to support the hypothesis that exposure to magnetic fields is a risk factor for leukaemia, according to a study of 73,051 electricity workers.
Findings for all combined leukaemia among the workers were “unexceptional”; risks were close to the norm for all exposure categories and there was no increase in risk with cumulative magnetic-field exposures.
There were also no statistically significant dose-response effects for either acute myeloid leukaemia, chronic myeloid leukaemia or chronic lymphocytic leukaemia.
