“…Such high efficiency indicators, which are 1.3-2 times higher than the same for the composition 0.5TeO 2 -0.4Bi 2 O 3 -0.1WO 3 are due not only to the change in glass density, but also to the electronic configuration and vacancy density, and therefore to the value of Z e f f , which directly depends on the glass composition. The data obtained are also in good agreement with the literature data [18][19][20] devoted to the study of the efficiency of WO 3 doping in various types of glasses and radiation-resistant ceramics. The prospect of the obtained data on the shielding efficiency opens up wide opportunities not only for the development of technology for creating such glasses, but also for further research in this direction in order to increase the shielding efficiency.…”

“…At the same time, despite quite a large number of scientific works in this area of research [16][17][18][19][20][21][22][23][24][25][26][27], there are still many unresolved issues related to the search for optimal compositions and structural compounds, which will combine high absorbing and weakening ability, as well as minimum thickness. One of the promising compositions for shielding materials is a composition containing TeO 2 , Bi 2 O 3 , WO 3 , a combination of which allows obtaining high values of density, stability and values of shielding efficiency [28][29][30].…”

This article is devoted to the study of determination of gamma radiation shielding efficiency by new radiation-resistant glasses of the 0.5TeO2-(0.5-x)Bi2O3-xWO3 type. As a method of obtaining glasses, the method of solid-phase synthesis combined with thermal annealing and subsequent hardening was used. The amorphous nature of the synthesized samples was confirmed by X-ray phase analysis. Determination of the shielding efficiency, as well as the effect of Bi2O3 and WO3 content in the glass composition on the attenuation efficiency was carried out by evaluation of gamma radiation intensities from the 137Cs source, with a gamma ray energy of 661 keV. The evaluation was performed on parameters such as radiation protection efficiency, linear and mass attenuation coefficients, half-value layer and mean free path. During the studies, it was found that glasses of the following composition 0.5TeO2-0.1Bi2O3-0.4WO3 are most effective, which are 1.3-2 times higher than those of the composition 0.5TeO2-0.4Bi2O3-0.1WO3.

As radiation is an essential tool in various technological applications, searching for a suitable shield is an urgent demand to minimize its damaging effects on human beings. In this research article, we report on the radiation shielding properties of some commercially available polymers namely poly(N-isopropylacrylamide), polyethylene terephthalate, polystyrene, and polycarbonate (denoted by P1, P2, P3, and P4, respectively). The gamma ray attenuation parameters are calculated using the Geant4 simulation, PHITS code, and XCOM program. Half value layer (HVL), linear attenuation coefficient (LAC), gamma dose rate at different energy levels, mean free path (MFP), specific gamma ray constant, effective atomic number (Z eff ) and effective electron density (N eff ), removal cross section for fast neutron, and total cross section for thermal neutron are investigated at energies of 0.01, 0.03, 0.05, 0.07, and 0.1 MeV.The results indicate that the highest LAC values were observed for P2 polymer at 0.1 MeV, while the lowest LAC values were noted for P3 polymer at 0.01 MeV among the studied commercial polymers. The total cross sections of thermal neutrons for the investigated polymers change from 24.0717 to 31.8611 cm −1 . Moreover, the MFPs and HVLs of the investigated polymers were very close to those of ordinary concrete and RS-253-G18 commercial glass, especially at the low energies. This suggests the utility of using the present polymer samples for shielding applications against gamma and/or neutron radiations.

“…The atomic number correlates positively with MAC, causing the highest radiation shielding capability in the glass sample G 1. Even so, the G1 glass can be the most superior attenuation abilities to the other glasses [35][36][37][38][39][40][41][42].…”

Quaternary glasses with a 59B2O3-29SiO2-2LiF-(10 − ) ZnO-TiO2 composition using the melt-quench techniques were prepared. XRD examined the nature of prepared glasses. The FT-IR spectra was studied for the changes in the structure of these glasses. While the density is increased, the molar volume of the glass system is reduced. The velocities and elastic modulus of these glasses were experimentally and theoretically based on the Makishima-Mackenzie model evaluated. Besides, for the studied glasses, the radiation shielding efficiency was investigated by Phy-X/PSD and XCOM software. These glasses were found to have an abnormal attenuation, structural, and density relationship. The mass attenuation coefficient (μ/ρ), linear attenuation coefficient (LAC), half-value layer (HVL), tenth value layer (TVL), and effective atomic number (Zeff), of glasses, have been designed to simulate for gamma photon energies between 0.015 and 15 MeV. MAC values calculated using Phy-X/PSD and XCOM were compared and was observed in good agreement with the other.
