As part of a program to determine which measures to use to control radioactivity from tailings piles at inactive uranium mills, the U. S. Environmental Protection Agency has prepared estimates of the potential for exposure to radioactivity presented by those piles. The ..gamma.. radiation field and the radon-222 release rate are estimated on the basis of the radium-226 concentration in each pile. Potential exposures to airborne particulate uranium, thorium-230 and radium-226 are estimated from field measurements. Dispersion of airborne material was calculated with adaptations of computer codes which use common models for annual-average and single-plume dispersion. (auth)
