“…Glasses could be used to attenuate potentially harmful radiations like gamma-rays, thereby using them as transparent radiation shields. Moreover, glass manufacturing is cost-effective, easily moldable, 100% recyclable capability, and glasses show high homogeneity and they are structurally, thermally, and mechanically stable depending upon the compositions, resulting in an attenuation efficacy [6][7][8]. Though, as radiation shields, lead (Pb)-based glasses or materials are being used at diagnostic imaging facilities, mainly 'Pb' element toxicity to the surrounding environment, working personnel, and cost restrict its usage.…”

“…For c-rays attenuation characteristic study for any material, mass attenuation coefficient (l/q) is an important physical parameter. Additionally, halfvalue layer (HVL), tenth-value layer (TVL), effective electron density (N eff ), effective atomic number (Z eff ), mean free path (MFP), exposure buildup factor (EBF), and energy absorption buildup factor (EABF) parameters are vital in understanding gamma radiation interaction through photoelectric absorption, Compton scattering, Rayleigh scattering, and pair production mechanisms with shielding material [6][7][8][9]. For the last few years, numerous research groups have been reported on gamma-ray shielding features of different glass systems using theoretical approaches and/or experimental methods.…”

Gamma-rays and fast and thermal neutron attenuation features of (Bi 2 O 3 ) x -(TeO 2 ) (100-x) (where x = 5, 8, 10, 12, and 15 mol%) and [(TeO 2 ) 0.7 -(B 2 O 3 ) 0.3 ] (1-x) -(Bi 2 O 3 ) x (where x = 0.05, 0.10, 0,15, 0.20, 0.25, and 0.3 mol%) glass systems have been explored and compared. For all samples, mass attenuation coefficients (l/ q) are estimated within 0.015-15 MeV photon energy range by MCNP5 simulation code and correlated with WinXCom results, which showed a satisfactory agreement between computed l/q values by these both methods. Additionally, effective atomic number (Z eff ), effective electron density (N eff ), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), total atomic cross-section (r a ), and total electronic cross-section (r e ) are calculated by utilizing l/q values. The l/q, Z eff , and N eff are energy dependent and have higher values at the lowest energy and smaller values at higher energies. Moreover, using the G-P fitting method as a function of penetration depth (up to 40 mfp) and incident photon energy (0.015-15 MeV range), exposure buildup factors (EBFs)

“…N. Chanthima et al investigated the impacts of BaO on the physical properties of zinc borate-based glasses. They recorded that the radiation-shielding parameters were enhanced as a function of BaO, and the decrement of γ-ray energy [ 43 ]. K. Boonin et al synthesized and inspected zinc barium tellurite glasses for their radiation-defense mechanism and structural behavior.…”

In-Silico Monte Carlo Simulation Trials for Investigation of V2O5 Reinforcement Effect on Ternary Zinc Borate Glasses: Nuclear Radiation Shielding Dynamics

In the current study, promising glass composites based on vanadium pentoxide (V2O5)-doped zinc borate (ZnB) were investigated in terms of their nuclear-radiation-shielding dynamics. The mass and linear attenuation coefficient, half-value layer, mean free path, tenth-value layer, effective atomic number, exposure-buildup factor, and energy-absorption-buildup factor were deeply simulated by using MCNPX code, Phy-X PSD code, and WinXcom to study the validation of ZBV1, ZBV2, ZBV3, and ZBV4 based on (100−x)(0.6ZnO-0.4B2O3)(x)(V2O5) (x = 1, 2, 3, 4 mol%) samples against ionizing radiation. The results showed that attenuation competencies of the studied glasses slightly changed while increasing the V2O5 content from 1 mol% to 4 mol%. The domination of ZnO concentration in the composition compared to B2O3 makes ZnO substitution with V2O5 more dominant, leading to a decrease in density. Since density has a significant role in the attenuation of gamma rays, a negative effect was observed. It can be concluded that the aforementioned substitution can negatively affect the shielding competencies of studied glasses.

“…Glass has features that make it distinct from other materials, such as visible light being able to pass through it, the ease of preparing glass in different and simple ways, and the possibility of changing the density of the glass during the preparation of glass samples. For these reasons, glassy materials are considered some of the most important materials currently used in radiation protection [12][13][14][15]. In order to enhance the photons attenuation ability of any glassy materials, we must use a glass systems which possesses relatively high density, and this is achieved by utilizing heavy metal oxides such as PbO, TeO 2 , etc.…”

This research work aims to investigate the radiation shielding ability of a Yb3+-doped calcium borotellurite glass system. The system has the basic composition of CaF2–CaO–B2O3–TeO2–Yb2O3 but is denoted as TeBYbn for simplicity. The effect of increasing the TeO2 content in the glasses from 10 to 54 mol% was investigated, with five different chosen compositions and densities. The Phy-X/PSD program was used to investigate the mass attenuation coefficient (µ/ρ) of the samples. The mass attenuation coefficients were theoretically determined by using an online software for the calculation of shielding parameters. Other parameters were then calculated and analyzed, such as the linear attenuation coefficient (µ), transmission factor (TF), radiation protection efficiency (RPE), effective atomic number (Zeff), and mean free path (MFP). TeBYb5, the glass with the greatest TeO2 content, was shown to have the greatest µ/ρ; however, at greater energies, the differences between the values are practically negligible. µ was shown to increase with density, such as from 0.386 cm−1 to 0.687 cm−1 for TeBYb1 and TeBYb5 at 0.284 MeV, respectively. The least TF was found for samples with a thickness of 1.5 cm, proving an inverse correlation between the thickness of the sample and the TF. The HVL and TVL of the glasses decreased as the density of the samples increased, which means that TeBYb1 is the least effective out of the investigated glasses. The five samples proved to have a lower MFP than some other shielding glasses, demonstrating their capabilities as radiation shields. Based on the calculated parameters, TeBYb5 indicated the greatest photon attenuation ability.
