ADULT CANCERS NEAR HIGH-VOLTAGE OVERHEAD POWER LINES
ISEE Conference Abstracts, 2013 Extremely low-frequency magnetic fields are designated as possibly carcinogenic in humans, based on an epidemiologic association with childhood leukemia. Evidence for associations with adult cancers is weaker and inconsistent.We conducted a case-control study to investigate risks of adult cancers in relation to distance and extremely low-frequency ...
