Colorless, tasteless, odorless and chemically inert, radon is generated by the natural decay of uranium. According to the National Academy of Sciences, radon exposure appears to be responsible for 13,000 lung cancer deaths in the United States each year; the American Lung Association considers prolonged exposure as dangerous as chain smoking.
The Environmental Protection Agency sets the “action level” for radon at four picocuries of radioactivity per liter of air. Dr. Einerson said that a level of 10 picocuries poses an increased lung cancer risk equal to smoking a pack of cigarettes a day for life.
