Estimation of North American population doses resulting from radon-222 release in western United States: methodology

The report represents a compilation of computer codes used to estimate potential human exposures and inhalation doses due to unit releases of 222Rn from uranium milling sites in western United States. The populations considered for potential exposure to risk from 222Rn and associated daughters are the inhabitants of North America between 200 and 600 North latitude. The primary function of these codes is to integrate spatially atmospheric radionuclide concentrations with current population data for the geographic area under consideration. It is expected that these codes will be of assistance to anyone interested in assessing nuclear or nonnuclear population exposures over large geographic areas
