Summary
The alpha dose to cells in bronchial airways in the beagle dog during historical exposures to ²²²Rn decay products is calculated using updated information on airway morphometry, call nucleus depth, mucus thickness, physical dosimetry and atmospheric characteristics. The alpha dose per unit exposure to basal call nuclei in the upper airways ranges from 2 to 7 mGy WLM{sup −1} (excluding the trachea) depending upon the exposure protocol used. The dose to alveolar tissue is 3 mGy WLM{sup −1}. In the human lung, the dose factor for the bronchial airways is 9 mGy WLM{sub −1} and for the pulmonary parenchyma 0.5 mGy WLM{sup −1} The human tumors appear primarily in the first few branching airway generations while the only tumors observed in the animals were in the bronchioloalveolar region suggesting a difference in cell sensitivity to alpha radiation.
