Fifty Year Dose Commitment to Various Organs and Tissues from Inhalation of exp 133 Xe

摘要

A metabolic model for a single inhalation of exp 133 Xe, together with the computer code in use at this Laboratory, was employed for estimating dose commitments to various organs and tissues in the adult human body. The code uses Monte Carlo data for photons and assumes complete absorption of the energy from the emitted electrons in organs and tissues. For bone, a model was used to estimate dose to red and yellow marrow and to endosteal cells of both trabecular and cortical bone. For a single inhalation of 1 mCi of exp 133 Xe, the 50 year dose to gonads was about 0.4 mrad. The dose to lungs from exp 133 Xe dissolved in tissues is about the same, but the dose to the lungs from exp 133 Xe in air spaces was about 1 mrad. (ERA citation 01:021262)
