Specific Absorbed Fraction for Photon and Electron to a Simple Stomach Model considering Stem Cells

Abstract

The aim of the present work has been the development of logical dosimetry for human alimentary tract. In this work, a stomach simple model with stem cells has been developed. Also, specific absorbed fractions for photon and electron to the stomach model have been evaluated in the energy range 10keV-4MeV using Monte Calro simulation. Consequently, it was found that photon SAFs to the stem cell in the stomach are more than those to the stomach wall. Electron SAFs to the stem cell in the stomach were also found to be less than that used in the radiological protection. It is concluded that the Monte Carlo simulation is very useful in the development of logical dosimetry for the stomach and that the determination of target tissue in the stomach is very important for the SAF evaluation.
