Summary: A set of boro-tellurite glasses doped with Dy3+ ions were prepared using the melt quenching method, and the radiation resisting aptitude of the glasses was evaluated through various structural and elastic features. The results showed that the molar volume decreased with increasing tellurium content, indicating the presence of more bridging oxygens in the glass structure. The rigidity, density, and connectivity of the glass increased due to the rise in cross-link density. Glass with 40% TeO2 exhibited high elastic moduli and good radiation shielding properties.

Summary: A new series of Niobium bariumtelluroborate glasses doped with Dy3+ ions were prepared with varying BaO concentrations. The amorphous nature of the glasses was confirmed by XRD investigation. FTIR spectra revealed diverse functional groups. The optical characteristics of the glasses were studied using UV-Vis spectral measurements. The structural and physical properties, as well as the shielding parameters, were estimated and discussed for the Dy3+ incorporated Niobium bariumtelluroborate glasses. The radiation shield capacity of the glasses was improved by increasing the BaCO3 concentration.

Summary: The Pakkanadu Ultramafic-Alkaline-Carbonatite complex in Salem district has been studied using geochemical and remote sensing methods. The study found that the dunite sample, with the highest Fe2O3 content, exhibited superior shielding properties. This suggests that the composition and density of the studied materials directly impact their properties, and that the superior shielding properties of dunite are worth investigating for other radiation types.

Summary: Evaluating the radiation shielding behavior of rocks is important for construction purposes. This study investigated the radiation shielding properties of Neoarchean mafic and ultramafic rocks from the Bhavani Shear Zone in southern India. The results showed that different band combinations and techniques can effectively discriminate and map the rock types and distribution. Additionally, a feasible container design for disposing of radioactive wastes was proposed using Monte Carlo simulation.

Summary: The effect of TeO2 on the radiation-shielding competence of a BaO-MoO3-B2O3 glass system was experimentally investigated. By measuring the attenuation factors of the prepared glass at different energies of γ-rays, it was found that the TeO2 content influenced the shielding performance of the glass. Among them, MTB5 glass with 70 mol% TeO2 exhibited the best shielding effect.

Summary: This study evaluated the structural, optical, and physical characteristics of glasses with different levels of In2O3 content, finding that increasing In2O3 content led to higher glass density, increased Urbach energies, and alterations in optical and absorption characteristics. Additionally, substituting ZnO with In2O3 significantly enlarged the optical band gap, and the gamma-ray mass attenuation coefficient showed consistent growth with higher In2O3 content. High concentrations of In2O3 in TeO2-ZnO glass were found to be beneficial for integrating structural, optical, and radiation properties.

Summary: A series of Bi2O3 varying BZX glasses were fabricated by melt-quenching method and examined for their physical, structural, elastic, and radiation-shielding properties. With increasing Bi2O3 concentration, the BZX glasses exhibited higher ionic nature and linear attenuation coefficient values. Among the investigated samples, BZ30 glass was identified as the more effective shield due to its highest MAC and LAC values.

Summary: In this study, five new strontium barium borate glasses doped with dysprosium ion and different concentrations of niobium pentoxide were synthesized. The glasses were investigated for their physical, structural, optical and gamma radiation shielding properties. It was found that the addition of niobium pentoxide increased the boron-boron distance and oxygen packing density, while decreasing the molar volume of oxygen.

Summary: A new ternary nanocomposite was prepared by doping polypropylene (PP) with nano-cadmium oxide CdO-NPs and nano-bentonite (Bent. NPs) for gamma-ray shielding. The addition of CdO NPs was found to enhance the linear attenuation coefficient (LAC) and improve the shielding competence of the fabricated nanocomposite. The study showed that increasing the content of CdO NPs in the composite significantly decreases the half-value layer (HVL) of the material, with the CdO NPs composite at 40 wt% being the superior shield among the fabricated samples.
