“…Furthermore, glasses are presently considered as one of the most effective materials for radiation shielding due to their multiple advantages over many other materials, such as high density, transparency to visible light, non-toxicity, and ease of manufacture [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Tellurite glasses, which are made of glass, have been shown to be excellent shielding materials for Gamma rays and neutrons [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

The synthesized glass system with a composition of (80-x) TeO2-10P2O5-10Nb2O5-xKCl mol% (where x = 5, 10, 15, 20, and 25) was successfully fabricated. The density (ρ) and molar volume (Vm) have been calculated. The investigated glasses were characterized using different analysis methods (differential thermal analysis (DTA) and UV-VIS-NIR spectroscopy). The radiation shielding effectiveness of the synthesized glass system was evaluated using different shielding parameters, such as mass and linear attenuation coefficients (MAC, LAC), half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), and effective electron number (Neff). The results showed that with the increasing potassium chloride (KCl) concentration and decreasing tellurium oxide (TeO2) concentration, the density, refractive index, Urbach energy (Eu), and glass transition temperature (Tg) decreased, while the optical energy gap (Eopt) and thermal stability increased. As the KCl concentration increases, the values of MAC, LAC, and Zeff increase in the following order: TPNK5 % > TPNK10 % > TPNK15 % > TPNK20 % > TPNK25 %. Additionally, the shielding effectiveness of TPNK glass system showed good performance compared with some standard materials. The synthesized glass with a minimum KCl content has both good shielding effectiveness and good optical properties, in addition to reasonable thermal stability, which makes it suitable for shielding and optical applications.

“…The HVL physically indicates the material thickness equivalence that reduces radiation intensity by 50%, while the MFP describes the average travelled distance between two successive photon interactions. 75 Issa et al reported that the HVL values fell as the ZnO concentration increased in the glass systems at photon energies of 0.662, 1.173, and 1.33 MeV, owing to a rise in the mass attenuation coefficient and density caused by replacing TeO 2 with ZnO. The half-value layer of the glass samples is lower than the comparable values for barite and ferrite concretes at 0.662 and 1.33 MeV photon energy, as illustrated in Fig.…”

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.

In this paper, bismuth oxide (Bi2O3) as the main functional powder, lead (Pb) and tantalum (Ta) as the metal additives, epoxy resin as the matrix and polyester–cotton blended woven fabric as the substrate, Bi2O3 coating nuclear radiation protection composite, Bi2O3/Pb coating nuclear radiation protection composite, and Bi2O3/Ta coating nuclear radiation protection composite with different process parameters were prepared. The cross-section scanning analysis and the influence factor analysis of γ-ray protection performance were carried out, and the mechanical properties of the composites were discussed. The results show that an increase in Bi2O3 content (mass fraction) and an increase in coating thickness can improve the shielding rate of the composite materials to γ-rays. When the thickness of the coating is 1.6 mm and the content of Bi2O3 is 50%, the shielding rate of the composite to γ-rays (at 59.5 keV) reaches 46.1%. The shielding rate of the composite can be increased by adding appropriate metal additives, and the effect of adding Ta is better than that of Pb. The shielding rate of the composite to γ-rays (59.5 keV) can be increased from 28.4% to 31.5% by adding 5% Ta. An increase in Bi2O3 content (mass fraction) and an increase in the coating thickness can aggravate the agglomeration of functional particles in the material. The addition of metal additives can reduce agglomeration to a certain extent. Bi2O3 content, coating thickness, and metal additives all have an effect on the mechanical properties of the composite. If the coating is too thick or the functional particle content is too high, the tensile strength and elongation at break of the composite will be reduced.
