Abstract: | Based on data representing standard Korean male adults, a mathematical anthropomorphic phantom was developed to calculate the specific absorbed fraction for several organs. The results were then compared against values calculated with other phantoms (OTOKO of Japan, MIRD of the U.S. and GOLEM of Germany). We compared the specific absorbed fractions of six organs (the adrenals, kidneys, liver, lungs, pancreas and spleen) for two cases: when the source and target organs are the same, and when they are different. When both the source and target organs are the same the organ with the highest specific absorbed fraction regardless of energy level was found to be the adrenals in all phantoms. In comparing phantoms, the phantom developed on the basis of standard Koreans produced the highest specific absorbed fraction. Also, as a result of conducting an assessment by separating source organs from target organs, the phantom developed on the basis of standard Koreans displayed relatively high specific absorbed fractions although there were slight differences per organ. |
