Tellurite glass systems become an essential component for several medical and nuclear technologies. Radiation shielding characteristics of a newly developed tellurite glasses containing Sb2O3 and V2O5 in energy range from 0.1 to 10 MeV are reported in this work. A FLUKA simulation along with a suitable theoretical model is carried out to examine the shielding performance of the involved glass system against gamma, neutron, and charged-particles radiations. HVLs of the TSP glasses vary in order of TSP-D

For safe immobilization of nuclear waste, lead-iron phosphate glasses are promising as high-level commercial and defense materials. In this research article, the compositional, elastic, and gamma shielding properties of the glasses containing (80 − x)P2O5– xFe2O3–20PbO with x = 20, 25, 30, 35 mol% were reported. The compositional and elastic parameters including the micro-hardness of the investigated glass samples were obtained based on Makishima-Mackenzie’s theory (MM-theory) and R model. We found that the deviation between these two methods decreased as Fe2O3 concentrations increased from 20 to 35 mol %. Additionally, γ-ray attenuation properties of the P2O5– Fe2O3–PbO glass system were evaluated using Geant4 simulation toolkit. The simulation results were compared with the theoretical ones extracted from Py-MLBUF software. The obtained results reveal that the MACs of the glasses vary from 0.030 to 40.014 cm2/g for PFP-A, from 0.031 to 41.502 cm2/g for PFP-B, 0.031 to 43 cm2/g for PFP-C and from 0.031 to 44.400 cm2/g for PFP-D. Maximum Zeff values of present glasses are obtained at 0.10 MeV whereas minimum Zeff values are obtained at 1.5 MeV. Finally, the fundamental γ-ray attenuation properties of the P2O5– Fe2O3–PbO glass system are found to be comparable with those of traditional and commercial radiation shields such as RS-253-G18 and RS-360 commercial glasses, ordinary concrete, barite concrete and TBZP10 from scientific literature. The results indicated that MFPs of the investigated glasses are lower than those of RS-360 glass, but they are higher than those of barite concrete and TBZP10.

Tellurite glasses own some unique properties that can serve human being developments in several applications. This research work aims to study the optical properties and radiation shielding performance of tellurite glasses containing Li2O and MoO3 described by the formula of xLi2O – (80–2x)TeO2 – (20+x)MoO3, where x = 0, 10, and 20 mol%. The results of the optical studies show that the optical transmission (T) of the studied glass samples increased from 1.21 to 1.42 as the Li2O content increased from 0 to 20 mol%. Such increase was associated with a clear decline in the values of the static dielectric constant of the samples. On the other hand, FLUKA simulation was extensively used to assess and test the radiation shieling performance for each sample involved. The findings of this part reveal that the attenuation factors (e.g. MACs) of LTM glasses varied from 0.038003 cm2/g to 0.16151 cm2/g for LTM-A, from 0.03813 to 0.15611 cm2/g for LTM-B and from 0.03825 cm2/g to 0.14948 cm2/g for LTM-C. Moreover, the transmission factors (e.g. HVLs) of the LTM glasses were minimum at 0.284 MeV with value of 0.814437 cm, 0.90430 cm and 1.03275 cm for LTM-A, LTM-B and LTM-C, respectively. Finally, a large scale comparison was achieved between the studied glass samples and the commercially available ones for several photon energies. This comparison confirmed the utility of using the present glass samples as transparent shielding materials in several applications whether this is in hospitals or any other technological facilities.
