Abstract
GATE/GEANT4 code-based Monte Carlo simulations have been conducted and validated for the purpose of studying the mass attenuation coefficient of xRmOn: (100-x) SiO2 glass systems (where RmOn are Bi2O3, PbO and BaO, with 30 ≤ x ≤ 70 % by weight) at 662 keV. The results came in agreement with the ones previously obtained through WinXcom program. Consistency between simulation and experimental results is confirmed by using χ2 test. The obtained results suggest the validity of using GATE for estimation of mass attenuation for different material compositions at different energies. This specific study recommends GATE simulation code as a suitable tool to investigate materials in the field of radiation shielding as an alternative to the experimental method.
