Radon risk factors; Evaluating the health implications of home exposure

Exposure to radon gas and its radioactive daughters in residences may be responsible for as many as 20,000 or more lung cancers each year. The lung cancer risk posed by radon is dependent upon those factors determining the behavior of radon daughters, including attachment to airborne particles, deposition on room surfaces and deposition in the human lung. The author presents an understanding of the behavior of radon daughters for the proper interpretation of radon and radon daughter measurement results, application of appropriate mitigation measures and assessment of the effect of a number of activities in the home.
