Epidemiological Studies of Residential EMF Exposures

by Robert B. Goldberg, Ph.D., Editor

Summary

In order to discuss effects of dosage it is necessary to have a standard for comparison. We reviewed several studies which attempted to demonstrate a standard metric for comparison of EMF exposure. One group published a study of the effect of using measurements from a single residence for each subject on the accuracy of exposure assessment. Another group did a comparison by taking measurements from one home and then evaluated the effect of adding information from another home for children who had lived in two homes. A group of University of Southern California investigators studied wire configuration and measurement data to create a model for estimation of EMF exposure. Then they compared the predictions of their models to actual measurements and the wire code in Los Angeles County. The epidemiological data for childhood leukemia from three studies were reviewed and reanalyzed and discussed. We also reviewed the work of another research group which developed a theoretical model for exposure based on proximity to power lines and exposure to a range of airborne pollutants. This review includes a letter to the editor of an epidemiology journal and reply. The first findings of the UK Childhood Cancer Study have appeared and are discussed. Several critiques and commentaries of the major negative studies on the role of residential power line frequency EMF as a factor in childhood cancers and leukemia are presented leading to a discussion of the differences within the scientific community regarding causes of childhood leukemia.
