An investigative series exploring the health hazards of radon gas cites the Iowa Radon Lung Cancer Study led by Bill Field, professor of occupational and environmental health, calling it “a seminal study on indoor radon exposure and health risk.”
In 1990, the EPA determined that an estimated 6% homes had potentially dangerously high levels of radon. Bill Field, Deputy Director at the Heartland Center, conducted a study from 1993 to 1996 on the health risks of radon exposure. Field and his colleagues found that risk of lung cancer can increase by 50% with long-term exposure to elevated levels of radon.
