Abstrakt: Regarding to their unique physical and mechanical features, glasses and glass-ceramics are suitable materials for shielding purposes. The present study evaluates the shielding properties of the CaF 2 -CaO-B 2 O 3 -P 2 O 5 -SrO-Ta 2 O 5 glass system using Monte Carlo GEANT4 and MCNPX codes for X-ray radiations with an energy range of 20 to 100 keV. MAC values of the Ta 0 , Ta 1 , Ta 2 , Ta 2.5 , and Ta 3 samples of the CaF 2 -CaO-B 2 O 3 -P 2 O 5 -SrO-Ta 2 O 5 glass were computed using Phy-X/PSD, GEANT4, and MCNPX codes and compared. According to the results, the programs have good compatibility with each other. For instance, in the energy of 40 keV and for the Ta 2 sample, GEANT4 and MCNP codes are 1.445765406 and 1.517801204 cm 2 /g, respectively, indicating 7.419529525 and 2.829628418% differences with 1.562 cm 2 /g obtained using the Phy-X/PSD software. According to recent estimations, the Ta 3 sample of the CaF 2 -CaO-B 2 O 3 -P 2 O 5 -SrO-Ta 2 O 5 glass system can be selected as the best shield compared with the other samples.
