Abstract
On the basis of the new ICRP-lung model the ratio of the absorbed alpha-energy or integral alpha-dose in the bronchial and pulmonary region to the inhaled potential alpha-energy is estimated as function of the aerosol concentration, the ventilation rate and the wall-deposition rate in the working area. With increasing aerosol concentration and decreasing ventilation rate this ratio decreases in the bronchial region but increases in the pulmonary region. Finally the possible variation of bronchial and pulmonary dose per WLM inhaled is discussed with respect to the maximum permissible annual intake of Rn- and Tn-daughters.Keywords
