Abstract
Lack of current actual field data on such factors as radon daughter equilibrium ratios and fractions of unattached radon daughter atoms and the relationship of the measured working levels to actual lung dose caused questioning of the working level concept as the basis for mine radiation control work. A simple technique for measuring equilibrium ratios and the fractions of unattached radon (10043922) daughter atoms in air using a wire screen prefilter to collect unattached atoms is described. Values obtained by this method in several United States uranium (7440611) mines are presented.
