- Summary
- The distribution of radiation dose commitments within the body that can result from the lung deposition of a number of transuranic radionuclides (237Pu, 238Pu, 239Pu, 240Pu, 241Pu, 242Pu, 243Pu, 244Pu, 241Am, 242Am, 243Am, 244Am, 242Cm, 243Cm, 244Cm, and 246Cm) was calculated. The variables that influence these organ dose commitments include the mobility of the particle or its dissolution products within the body, the radiation characteristics of the inhaled radionuclides and their progeny, and the size of the particles inhaled. In the calculation of organ dose commitments for whole-body, lungs, liver, bone tissues, kidneys, and gastrointestinal tract from the inhalation of transuranium radionuclides, physical characteristics of importance are the dimensions of the particle, its aerodynamic properties, and its density. For particles within the respirable size range, a useful description is provided by the activity median aerodynamic diameter. Dose commitments resulting from acute inhalation of plutonium, americium and curium nuclides relative to the activity median aerodynamic diameter (AMAD) were calculated using the computer program DACRIN. Deposition efficiencies were estimated for several regions of the respiratory tract as a function of the AMAD. These locations within the respiratory tract are described as the nasopharyngeal, the tracheobronchial, and the pulmonary regions. The deposition, migration, and retention of particles introduced into the respiratory tract are represented by descriptive mathematical models of these phenomena within the respiratory system. Estimates of the risk of excess deaths from cancer due to whole-body radiation doses are included in the calculations to provide an estimate of cancer death risks associated with the inhalation of transuranic compounds. These results are then equated to those from whole-body radiation doses. (CH)
