The purpose of this short-term study has been: (1) to develop broad bases; and (2) to obtain new information relevant to the needs of the Environmental Protection Agency. These data bases are required to provide information for the Clean Air Act and the Uranium Mill Tailings Radiation Control Act. This report, Part 1, deals specifically with four tasks associated with the Clean Air Act. They are: (1) Effect of bulkheading or filling underground mines on radon emission; (2) Radon daughter equilibrium at various distances from exhaust vents of underground uranium mines; (3) Incentives for using elevated release points to reduce ground level radon concentrations from underground uranium mines; (4) A study of the contribution of multiple radon sources in the Ambrosia Lake District, New Mexico, to concentrations at selected locations.
