Abstract
In this study, the mass attenuation coefficients were evaluated for Bi2O3ZnOB2O3 and TeO2ZnOCdOLi2OV2O5 glass systems for gamma ray energies of 0.356, 0.662, 1.173, and 1.330 MeV using MCNP5 and Geant4 simulation codes. The results obtained were compared with XCOM data. The simulation results obtained by both codes were in sufficiently good agreement with the XCOM data. Different shielding parameters such as the effective atomic number, half value layer, and mean free path were evaluated at the same energies based on the mass attenuation coefficients obtained. The results confirmed that the effective atomic number values for the Bi2O3ZnOB2O3 glass system increased with the Bi2O3 content, but decreased as the Li2O content increased in the TeO2ZnOCdOLi2OV2O5 glass system. The results demonstrated that the 60Bi2O340B2O3 glass sample (for the Bi2O3ZnOB2O3 glass system) and 64TeO215ZnO20CdO1V2O5 glass sample (for the TeO2ZnOCdOLi2OV2O5 glass system) are the most effective shields. The shielding properties of these two glass systems were compared in terms of the mean free path with previously reported standard shielding glasses, including some commercially available shielding glasses developed by Schott and different standard shielding concretes.
