“…For this purpose, the study will focus on calculations and simulations of SiO 2 -Na 2 O-CaO glasses with different contents of Sb 2 O 3 (see below), which have emerged in different applications [5]. Heavy metal oxide (HMO) glasses, such as Bi 2 O 3 , Sb 2 O 3 , and PbO, have been investigated due to their interesting properties in infrared and nonlinear optics [6]. Additionally, soda-lime-silica glasses are currently the subject of extensive research because of their various applications in medical and dental fields, in addition to their utilization in industrial applications [7,8].…”

Elastic moduli were theoretically computed using the Makishima–Mackenzie model for SiO2–Na2O–CaO glasses doped with Sb2O3 contents. The calculated elastic moduli (Young’s, bulk, shear, and longitudinal modulus) were observed to increase with an increase in the Sb2O3 contents. The microhardness showed an increase, while Poisson’s ratio decreased with the rise of the Sb2O3 contents. In addition, gamma-ray and neutron shielding parameters were evaluated for the investigated glasses. The linear attenuation coefficient (LAC) was simulated using the Monte Carlo N-particle transport code (MCNP-5). Other parameters, such as the mass attenuation coefficient (MAC), transmission factor (TF), and half-value layer, were calculated based on the simulated LAC. The addition of Sb2O3 content was observed to enhance the investigated glasses’ shielding parameters, where the highest LAC was achieved for the SCNSb10 glass with 10 mol% Sb2O3 and decreased from 0.441 to 0.154 cm−1 at gamma energies between 0.248 and 1.406 MeV. Furthermore, the fast neutron effective removal cross-section (∑R) was computed theoretically. The calculated results showed that the highest ∑R was equal to 0.0341 cm2g−1 and was obtained for the SCNSb0 glass, which had no Sb2O3 content, while the lowest ∑R was equal to 0.0286 cm2 g−1 for the SCNSb10 glass sample. The present work was carried out to examine the advantages of the soda–lime glasses with different Sb2O3 contents in several photon shielding applications, especially for radiation safety in nuclear installations.

“…5) that at each energy, LAC increased with the increase in Eu 2 O 3 concentration, A material having high Z eff values contains more atoms to encounter the radiation photons, thus improving the radiation shielding property of that material. The following relation was utilized by PSD/Phy -X software [52,56] to produce the Z eff values in the 0.015-15 MeV photon energy region:…”

Physical, optical, thermoanalytical, and radiation response study of Eu2O3-doped zinc fluoro-telluroborate glasses

In the present study, Eu3+-doped zinc fluoro-telluroborate transparent glasses were prepared by the conventional melt−quench technique. Their density and refractive index values were measured, and using these values, different physical parameters (number density, oxygen packing density, no. of bonds/vol, etc.) were calculated and analysed. The XRD pattern displayed a disordered atomic arrangement in the glass network. The EDS spectra proved the purity of the samples exhibiting only those elements used during the synthesis. The good solubility of Eu3+ ions in zinc fluoro-telluroborate glasses was analysed through fine absorption peaks in the UV−Vis−NIR range. The absorption intensities increased in all samples up to 3.0 mol% of Eu3+-doping concentration. The stabilities of the samples, such as ∆T ~ (144–156) °C and Hr ~ 2.33–4.00, calculated using characteristic temperatures (Tg, Tx, Tc, Tm) from DSC studies exhibited their promising candidature in a high-temperature environment. The Eu7 (Eu3+ with 3.0 mol%) glass confirmed better attenuation properties (LAC, Zeff, HVL, MFP) compared to other composition (0–2.5 mol%) glasses.

“…19 Bismuth borosilicate glasses have a high potential as shielding materials, and it is possible to increase the shielding capabilities by replacing the bismuth with bismuth nanoparticle size. 19,20 Other than that, the addition of heavy metal oxides, such as BaO, significantly affects the structure of the glass by converting the glass's BO 3 units into BO 4 units. 15,21 It leads to forming a stable glass shape capable of withstanding high-energy gamma radiation at high dosages.…”

Silicate glass is a popular radiation shielding material due to its abundance on Earth. However, due to simplicity of fabrication, tellurite-based optical glass materials became the primary glass network forming, garnering great scientific and technological relevance for their future uses. Previous studies have stated that the silicate and tellurite glass system might be employed in shielding applications, with metal oxide concentrations balanced with SiO2 and TeO2 content. The inclusion of SiO2 and TeO2 in the glass composition reduces the impact of radiation. In electron radiation, electron interaction activities with glass are more substantial in the low electron energy area. Meanwhile, the proton attenuation factors of the glass samples are smaller than the electrons. There is no discernible difference in the fast neutron effective removal cross-section (ΣR) values of the glass samples in neutron radiation. In the studies of tellurite glasses for gamma radiation shielding, the photon interaction parameters change as a function of material density. The measurements show that adding TeO2 to glass samples improved the gamma protection characteristics of the glasses. This review explains the various material compositions and presents a more in-depth analysis of radiation shielding properties in silicate and tellurite glasses.
