Reassessment of factors influencing lung dose from radon daughters
Recent research findings allow for better representation of several biological and physical factors in the modeling of dose to the lung from exposure to radon daughters. New information is available on the efficiency of the nose in filtering unattached radon daughters from inhaled air, the thickness of bronchial epithelium and location of sensitive target cells, the size distribution of unattached daughters and of the fraction of daughters attached to room aerosols, and the variability of these aerosol conditions in actual homes. This information is used here in an updated dosimetry model to reassess the relationship between indoor exposure and bronchial dose, and to evaluate variability with room conditions. 17 refs., 7 figs.
