ABSTRACT
The principal interest in the possible health impacts from air exposure to volatile constituents from the domestic use of water has centered on radon-222 and the short-lived daughters. Prichard and Gesell [1] concluded from their studies that such exposures in the general population of Houston, Texas, alone can produce annual total population doses of the same magnitude as that to the United States population as a result of these radioisotopes mobilized by the mining and milling of uranium. They stated that “radon carried by groundwaters might be an important source of population exposure nationwide.”
