CALCULATION OF ORGAN AND TISSUE BURDENS AND DOSES RESULTING FROM AN ACUTE EXPOSURE TO A RADIOACTIVE AEROSOL USING THE ICRP TASK GROUP REPORT ON THE HUMAN RESPIRATORY TRACT

摘要

The report of the Task Group on Lung Dynamics for Committee II of the International Commission on Radiological Protection (ICRP) is used as the basis for the derivation of equations for the calculation of organ and tissue burdens and radiation doses resulting from an acute inhalation exposure to a radioactive aerosol. Equations for the doses to sections of the gastrointestinal (GI) tract are derived for the variable daily input to the GI tract following an acute inhalation exposure. These latter equations are based on the approach of Dolphin and Eve for the dosimetry of Eve's new GI tract model. The derived equations are used to calculate the organ and tissue doses resulting from an acute exposure to 239puC>2 as a function of time after exposure. A FORTRAN-63 computer program written to simplify the application of the derived equations is appended.
