Summary: This study examines the shielding properties of the WO3-MoO3-TeO2/Sb2O3 glass system against gamma photons, neutrons, and charged particles. The study finds that the glass system has the lowest linear attenuation coefficient and mass attenuation coefficient at 6 MeV, while the highest values are observed at 0.10 MeV. The minimum half-value layers are found at 0.10 MeV, and the maximum half-value layers occur at 6 MeV. The study also analyzes the mean free paths, effective electron densities, gamma dose rates, and cross-sections for fast and thermal neutrons.

Summary: This paper presents an extensive evaluation of the nuclear shielding features of Ni-, Fe-, Pb-, and W-based alloys using FLUKA simulations and XCOM nuclear database. The findings show that FLUKA is an accurate technique for developing new alloys for shielding applications in nuclear sites. The radiation protection efficiency varies for different alloys at 0.284 MeV, while the neutron cross sections of the studied alloys are similar, with no significant variation with chemical compositions.

Summary: The effect of WO3 doping on the optical and shielding properties of the TeO2B2O3 glass system was investigated in this study. The results showed that WO3 doping decreased the density of the glass samples and increased the molar volume. Optical analysis revealed that WO3 doping changed the values of direct and indirect optical band gaps. In terms of radiation shielding, the glass sample with the highest percentage of TeO2 exhibited the best shielding performance.

Summary: The impact of Fe2O3 content on the optical properties and radiation shielding efficiency of the 10.5CaO+16.5Na2O+(73-x)B2O3+xFe(2)O(3) glass system (x = 0, 5 and 10.5 mol. %) for energies up to 15 MeV is studied. The optical properties of the glasses are investigated by calculating factors such as reflection loss, metallization criterion, optical transmission, and static dielectric constant. FLUKA simulations are used to evaluate and extensively study the radiation shielding efficiency of the glassy systems. It is found that the Fe2O3 content has a significant influence on the optical properties and radiation shielding efficiency of the glass system, indicating its potential use in hospitals and nuclear facilities where shielding applications are required.
