Risk Research: When Should We Say "Enough"?
M. Granger Morgan · 1986
Government agencies invested heavily in research examining whether 60-hertz electromagnetic fields from power lines pose health risks. The research demonstrated that low-frequency fields can produce changes in living systems under specific circumstances but has not demonstrated that a hazard exists. Laboratory animal screening studies largely failed to find adverse health impacts, and epidemiological studies linking long-term exposure to cancers were inconclusive. The scientific evidence neither clearly indicates a significant risk nor clearly indicates little or no risk from 60-hertz field exposures.
