Abstract:
A high performance simulation method is an essential research tool, especially for some complicated problems related to the radiation exposure and human health. In this paper, we study the radiation-transmission and self-absorption factors of the newly developed P2O5 & nbsp;- SrO - Sb(2)O3 glass system using 3D Geant4 simulations. The validation of our results is presented against a collection of theoretical methods by calculating the mass/linear attenuation coefficients (MAC & LAC). A good agreement between our simulation results and the theoretical ones demonstrates that the present simulation model can be helpful for solving further problems in the radiation shielding field. The obtained data are then utilized to assess the radiation shielding efficiency and half value layer for the samples within P2O5 & nbsp;- SrO - Sb2O3 glass system. Finally, we compare the shielding competence of our glass system with the published data of several standard shields. The results reveal that the mean free paths (MFPs) of PSS4 glass sample are smaller than those of RS-253-G18 (standard shield) and ordinary concrete. This means that the Sb2O3 content may play a beneficial role to improve the shielding competence of the present glass system. Therefore, the P2O5 & nbsp;- SrO - Sb2O3 glass system has a potential use to be a successful application for radiation protection (shielding) in the nuclear sites.
