Doses due to incorporation by ingestion of beta emitters
Dose calculation due to the incorporation of radionuclides is performed using the committed equivalent dose coefficients h(50) and the committed effective dose coefficient e(50). In this work we evaluated the dose coefficients for single ingestion of 3H, 14C, 32P, 35S using the values of the specific absorbed fraction (SAF) from the male reference computational phantom of the ICRP (International Commission on Radiological Protection). We used the human alimentary tract model, HATM, for determining the total number of nuclear disintegrations (Us) and the ICRP 103 methodology was followed. In general was found that the committed equivalent dose coefficients for most of the organs have relatively few differences, except for some organs such as the walls of the stomach, colon and bladder, also was found that there are significant differences in the doses in red bone marrow (RBM) and the bone surface (BS) for the particular case of ingestion of 32P.
