“…It can be inferred that an expansion in the glass network was occurred with the addition of bismuth oxide, which may be due to increase nonbridging oxygen bonds and larger ionic radius of Bi 3+ (1.03 Ǻ) compared to B 3+ (0.27 Ǻ). This result is consistent with previous related studies 41,42 . This explanation was reinforced when the values of oxygen packing density reduced (126.919 to 77.806 g.atom.l −1 ) with increasing of Bi 2 O 3 content.…”

The current study shows a new attempt to develop gamma‐ray shielding glasses. The proposed glass is a borate‐base composition modified with sodium and cadmium oxides and different concentrations of bismuth oxide. Based on the melt‐quenching technique, we prepared four glass compositions of 20NaO‐15CdO‐ (65−x)B2O3‐xBi2O3, where x = 0, 10, 20, and 30 mol%. The amorphous nature of the prepared samples was confirmed by XRD. To get more details about the structure, FTIR and UV‐Vis‐NIR were performed to characterize the prepared glasses. Moreover, we used ab initio molecular dynamics simulations to create the possible structures of the new compositions, and compared with the experimental measurements. A series of shielding parameters was investigated based on the gamma‐ray emission in the range of 0.01‐10 MeV. The results revealed an improvement of the shielding parameters with increasing of Bi2O3 content. The sample with the highest Bi2O3 (S4) has the highest Zeff and least HVL, while S1 (with no Bi2O3 content) has the lowest Zeff at all energy levels. The gamma‐ray transmission factor of the prepared glasses was compared with some commercial concretes. Finally, the new glasses especially with highest Bi2O3 are recommended to use in gamma radiation shielding facilities.

“…13) become the most dominate interactions, where this occurs specifically for E > 1.022 MeV [44,45]. These results (dependent of µ/ρ on the photon energy) are corresponding with the recently published literature on different materials like rocks [44], glasses [46][47][48][49][50], bricks [51], and amino acids [52]. Comparison with other glasses; like tellurite glasses [53][54][55] could be suggested.…”

In the present study, the optical characterization of borate glasses with composition 35Li 2 O − 10ZnO − 55B 2 O 3 − xMnO 2 : x = 0, 0.5, 1.0, 1.5, and 2.0 wt% has been investigated. The absorption spectra measurements within the wavelength domain 200-1000 nm have been carried out. The optical energy gap of the investigated samples using the absorption spectrum fitting (ASF) model has been calculated. The molar refraction, molar polarizability, reflection loss, optical transmission for the samples were estimated. The metallization criterion, dielectric constant, refractive index, and energy band metallization criterion for the studied glasses were estimated. Magnetic property measurements for all glass samples were carried out at 300 K. Additionally, the prospects of gamma-ray interactions with the investigated glasses have been achieved through studying the total mass attenuation, coherent, Compton, photoelectric, and pair production interactions at photon energy in the range of 0.356-1.330 MeV. Results reveal that the optical and magnetic properties of the investigated glasses change with changing the MnO 2 concentration. Studied glasses can be used as a candidate for optical fiber and optical devices application. In the other hand, at lower gamma photon energy range, the photoelectric absorption dominates with the glasses, while as the energy increases, the probability of Compton scattering and pair production become the most dominate interactions.

“…In the field of advanced materials, glasses are promising ones due to their numerous applications as well as their physical and chemical characterizations such as ease of designing, high corrosion resistance, optical transparency, and environment friendly. Previously, many opaque materials such as concrete were suggested as shielding materials for gamma radiation, however, there are several risks and limitations associated with their use [1,2]. Currently, glasses have the largest interest as promising radiation shielding materials to be used in the windows and doors in medical diagnostic labs, x-ray rooms and CT scans, scintillators, radiation therapy chambers, and in space technology [3,4].…”

This paper examines the gamma-ray shielding features of some selected tellurite-based glasses in the form of xMoO 3 (100−x)TeO 2 (20 x 50 mol%). Mass attenuation coefficients (μ m ) of these glasses have been calculated using Geant4 toolkit and XCOM program for photon energy range of 1 keV-1000 MeV. The correlation factor (R 2 ) between these two methods was found to be almost one. Shielding effectiveness for these glasses has been estimated by computing half value layer (HVL), effective atomic number (Z eff ), and mean free paths (MFP). It was noticed that the heavy metal oxide of TeO 2 plays an important role in improving the shielding effectiveness of the glasses. The Mo20Te80 glass has shown the promising properties to serve for gamma ray protection applications as compared with many conventional concretes and other newly developed glasses.
