Abstrakt: Knowledge of SAF at different energies is crucial for internal dosimetry. For this purpose, a set of calculated SAF values for a mouse voxelized phantom's selected organs are presented below. Values of SAF were calculated for mono-energetic photons and electrons with energy varying from 10 keV to 4 MeV using the Monte Carlo simulation via GATE/GEANT4 code (GEANT4 Application for Emission Tomography). The heart, liver, lungs, kidneys, and spleen were considered as the source organs from which the particles were released. Then, the estimated results were compared to those calculated in a previous study using EGS4 code. It is indicated that the obtained results are in good agreement with the reference values for all energies of photons and electrons, with discrepancies less than 9% and 5% for self-irradiation and cross-irradiation, respectively.
