Four sulfide compounds' attenuation features of gamma-ray (Ag 2 ZnSnS 4 , Ag 2 ZnSnSe 4 , ZnS, and Ag 2 S) were described in this paper by a new software Phy-X/PSD. We calculated radiation attenuation parameters for the selected samples for a broad range of energies (0.015–15 MeV), including linear attenuation, the mean free path, the half-value layer, and total atomic and electronic cross-sections. The effective atomic number and the effective conductivity were also analyzed to investigate the radiation attenuation features. Also, the analyzed samples' buildup factors were studied. The samples' parameters were compared to materials frequently used to shield against radiation, including ferrite, chromite, barite, magnetite, and RS (253 G18, 360, 520) glass. Due to MFP and HVL values, Ag 2 S has better attenuation features than all the other samples utilized in the comparison. Fast neutron removal cross-sections (FNRCS) were also studied, and the best neutron attenuation composite among the samples under study, according to the FNRCS data, is Ag 2 S (0.116 cm−1).

This paper examines the nuclear shielding characteristics for two different lead-zinc-tellurite glass systems with the composition of TeO 2 –Bi 2 O 3 – ZnO–PbO and TeO 2 –Na 2 O – ZnO–PbO coded as series A and series B, respectively. Nuclear shielding features of these glasses have been tested in terms of mass attenuation coefficient (μ/ρ), half value layer (HVL), removal cross section (∑ R), exposure buildup factor (EBF), effective atomic number (Z eff), and mean free path (MFP). The μ/ρ values of these systems were generated by Geant4 Monte Carlo simulations over an extended energy range of 0.015–15 MeV. The generated data of μ/ρ were confirmed by XCOM calculations. The results show that the nuclear shielding ability of the lead-zinc-tellurite system increases as Bi 2 O 3 content increases in the glasses of series A and as PbO content increases in the glasses of series B. Moreover, the nuclear shielding ability of the current glass systems have been compared with those of some conventional shielding materials and commercial glasses. It can be concluded that the present lead-zinc-tellurite glass systems could be useful to serve as novel shields for nuclear protection applications. • Lead-zinc-tellurite glasses are reported for nuclear shielding application. • Geant4, XCOM, and G-P methods are used for computational work. • Influence of Bi2O3/PbO on the shielding properties is discussed in details. • TBZP10 glass was found as promising alternative for the conventional shields.
