“…Transparent radiation shielding materials, as opposed to opaque radiation shielding materials, serve an essential role in nuclear engineering research because they provide substantial radiation protection while still being visible [1]. Recently, glasses have been considered as an alternative radiation shielding material due to properties such as their transparency, ease of manufacturing, nontoxicity, and high density [1][2][3][4][5][6][7][8]. Glass must be uniform in density and composition when used as a radiation shielding material.…”

In this study, the X-ray and gamma attenuation characteristics and optical properties of a synthesized tellurite–phosphate–sodium oxide glass system with a composition of (85 − x)TeO2–10P2O5–xNa2O mol% (where x = 15, 20, and 25) were evaluated. The glass systems we re fabricated by our research group using quenching melt fabrication. The shielding parameters of as-synthesized systems, such as the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), effective atomic number (Zeff), half-value layer (HVL), tenth value layer (TVL), mean free path (MFP), and effective electron density (Neff) in a wide energy range between 15 keV and 15 MeV, were estimated using well-known PHY-X/PSD software and recently developed MIKE software. Herein, the optical parameters of prepared glasses, such as molar volume (VM), oxygen molar volume (VO), oxygen packing density (OPD), molar polarizability(αm), molar refractivity (Rm), reflection loss (RL), and metallization (M), were estimated using MIKE software. Furthermore, the shielding performance of the prepared glasses was compared with that of commonly used standard glass shielding materials. The results show that the incorporation of sodium oxide into the matrix TeO2/P2O5 with an optimum concentration can yield a glass system with good shielding performance as well as good optical and physical properties, especially at low photon energy.

“…Various conventional concretes (barite, chromite, ferrite, and magnetite) and available commercial glasses (RS-520, RS-360 and RS-253) utilized for radiation shielding materials were compared for HVL values against the S 5 sample (36). As demonstrated in Figure 6, the HVL values of S 5 oxide glass and these concretes had the same energy.…”

Radiation-shielding applications are necessary to protect against deleterious effects of radiation. This study tested thulium oxide (Tm2O3) added to the glass-system composition 64TeO2–10WO3–10Nb2O5–15KF–1La2O3. Adding Tm2O3 increased sample density from 5.22 to 5.40 g/cm3 and measured at photon energy of 15 keV–15 MeV. Multiple radiationshielding parameters were evaluated and assessed using photon-shielding and dosimetry software, including linear and mass attenuation coefficients, half-value layers, mean free paths, atomic and electronic cross sections, effective atomic numbers, effective electron density, and exposure buildup factors. Half-value layer and mean free-path values were compared with those of well-known radiation-shielding materials, ie, conventional concrete and commercial glasses. Atomic and electronic cross-section values effectively increased with the addition of thulium oxide to the glass systems. While the highest linear and attenuation coefficients were 242–281 cm2 /g at 15 keV, the denser glass recorded the highest mass attenuation coefficients value of 52.17 cm2 /g across all samples. The highest effective atomic number and effective electron density were recorded for the denser glass, because it had the highest thulium oxide fraction and was more burdened by interaction with photon energy. Half-value layers and mean free paths showed similar behavior, and high-density materials achieved low values. At high energy, exposure buildup-factor values increased, while at low energy, values decreased.

Novel glass samples with the composition 75TeO2–5Ta2O5–15Nb2O5–5x (where x = ZnO, MgO, TiO2, or Na2O) in mole percent were prepared. The physical, optical, and gamma radiation shielding properties of the glass samples were studied over a wide energy spectrum ranging between 0.015 and 20 MeV. The glasses’ UV–vis spectra were utilized to evaluate the optical energy gap and refractive index. Glass samples had a refractive index ranging from 2.2005 to 2.0967. The results showed that the sample doped with zinc oxide (ZnO) recorded the highest density (ρglass), molar polarizability (αm), molar refraction (Rm), refractive index (n), and third-order nonlinear optical susceptibility (χ3) and the lowest optical energy gap (Eopt) among the samples under investigation. When comparing the current glass system with various standard glass shielding materials, the prepared glass system showed superior shielding performance at energies ranging between 40 and 85 keV. These findings indicate that the prepared glass systems can be used in diagnostic X-rays, especially in dental applications.
