Abstract
Background: Magnetic fields (MF) from AC electricity are a Possible Human Carcinogen, based on limited epidemiologic evidence from exposures far below occupational health limits. Methods: To help formulate government guidance on occupational MF, the cancer cases prevented and the monetary benefits accruing to society by reducing workplace exposures were determined. Life-table methods produced Disability Adjusted Life Years, which were converted to monetary values. Results: Adjusted for probabilities of causality, the expected increase in a worker's disability-free life are 0.04 year (2 weeks) from a 1 microtesla (microT) MF reduction in average worklife exposure, which is equivalent to $5,100/worker/microT in year 2010 U.S. dollars (95% confidence interval $1,000-$9,000/worker/mT). Where nine electrosteel workers had 13.8 microT exposures, for example, moving them to ambient MFs would provide $600,000 in benefits to society (uncertainty interval $0-$1,000,000). Conclusions: When combined with the costs of controls, this analysis provides guidance for precautionary recommendations for managing occupational MF exposures.
