Abstract:

Large quantities of radiopharmaceuticals prescribed for treatment and diagnosis are excreted through kidney. Therefore, radiation unwanted dose is created in kidney. As a result, exact calculation of prescribed radiopharmaceuticals amount is important. Monte Carlo method is used for simulation ofradiation transport in body due to random nature of radiation. In this research, for the first time kidney is considered integrated and for the second time it is considered that it has three areas; beta absorbed dose is calculated and compared in cortex and medulla kidney using MCNPX code to identify a more accurateway to prescribe radioisotope. The results showed that beta absorbed dose in medulla is 4 times as much as dose in integrated kidney and beta dose in cortex is 0.004 to 0.012 times as much as dose in integrated kidney. Internal structure of kidney should be considered in simulation to achieve a more accurate prescribed dose.
