Sm2O3 effects on mass stopping power/projected range and nuclear shielding characteristics of TeO2–ZnO glass systems

Abstract

This work aims to research not only neutron and gamma shielding specialties of Sm2O3-doped TeO2–ZnO glasses but also mass stopping power (MSP) and projected range (PR) for alpha and proton particles. Mass attenuation coefficient (μ/ρ) of 60(TeO2)–(40−x)ZnO–x(Sm2O3): x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5 mol%) glasses were obtained using GEANT4 Monte Carlo codes and WinXCOM software. A good agreement was observed between the two outcomes. The insertion of Sm2O3 into the glasses raised the μ/ρ values. It was found that TZSm0.4 glass owns lowest MFP, HVL and TVL values than the other glass samples due to its high specific gravity. Besides, the additive material increased effective atomic number (Zeff) values while the Exposure (EBF) and Energy Absorption (EABF) Buildup Factors decreased which are computed at 0.015–15 MeV photon energies up to 40 mfp. This shows that the addition of Sm2O3 improves the performance of glasses to reduce gamma radiation. Moreover, fast neutron macroscopic cross-sections (ΣR) of the glasses were specified. MSP and PR values were also computed for proton (H1) and alpha (He+2) particles. The outcomes display that the specific gravity of the TZSm glasses are extremely influential on neutron, alpha and proton shielding. With the largest ΣR and lowest PR values, the TZ0.4 glass showed the ability to stop both neutral and charged particles. It can be deduced that TZSM glasses with Sm2O3 addition may be preferred shield materials in the sense of gamma, neutron, alpha and proton attenuation.
