“…Due to its non-transparent characteristics, it is not possible to observe/monitor the internal environment. Moreover, variation in water quantity in concrete often exhibits unwanted fluctuations in attenuation coefficients 8 , 9 . To overcome such limitations, several glass-based materials have been processed.…”

Nuclear radiation shielding capabilities for a glass series 20Bi2O3 − xPbO − (80 − 2x)B2O3 − xGeO2 (where x = 5, 10, 20, and 30 mol%) have been investigated using the Phy-X/PSD software and Monte Carlo N-Particle transport code. The mass attenuation coefficients (μm) of selected samples have been estimated through XCOM dependent Phy-X/PSD program and MCNP-5 code in the photon-energy range 0.015–15 MeV. So obtained μm values are used to calculate other γ-ray shielding parameters such as half-value layer (HVL), mean-free-path (MFP), etc. The calculated μm values were found to be 71.20 cm2/g, 76.03 cm2/g, 84.24 cm2/g, and 90.94 cm2/g for four glasses S1 to S4, respectively. The effective atomic number (Zeff)values vary between 69.87 and 17.11 for S1 or 75.66 and 29.11 for S4 over 0.05–15 MeV of photon-energy. Sample S4, which has a larger PbO/GeO2 of 30 mol% in the bismuth-borate glass, possesses the lowest MFP and HVL, providing higher radiation protection efficiency compared to all other combinations. It shows outperformance while compared the calculated parameters (HVL and MFP) with the commercial shielding glasses, different alloys, polymers, standard shielding concretes, and ceramics. Geometric Progression (G-P) was applied for evaluating the energy absorption and exposure buildup factors at energies 0.015–15 MeV with penetration depths up to 40 mfp. The buildup factors showed dependence on the MFP and photon-energy as well. The studied samples' neutron shielding behavior was also evaluated by calculating the fast neutron removal cross-section (ΣR), i.e. found to be 0.139 cm−1 for S1, 0.133 cm−1 for S2, 0.128 cm−1 for S3, and 0.12 cm−1 for S4. The results reveal a great potential for using a glass composite sample S4 in radiation protection applications.

In this study, borosilicate host (H) and seven (S1-S7) samples are prepared by traditional melt-quenching technique. The samples are singly (S1, S2) and doubly (S3-S7) doped with deferent contents of Tb3+ and Dy3+ ions. All samples are analyzed and characterized by XRD (x-ray diffraction), ATR-FTIR (Attenuated total Reflectance-Fourier transform infrared) spectroscopy, TGA/DSC (Thermogravimetric analysis/Differential scanning calorimetry), and Raman spectroscopy. Moreover, the radiation shielding parameters of mentioned glasses such as mass attenuation (?/?), mean free path (MFP), and half-value layer (HVL) are evaluated within the energy of 0.015MeV-15MeV. These parameters are theoretically investigated and evaluated by using XCOM, WINXCOM, and Phy-X programs in addition to the other relevant equations. The ATR-FTIR measurement and Raman spectroscopy results confirmed the unit structure of BO3 and BO4 groups as the main compound as well as the Aluminum-oxide (Al-O-Al) and zinc-oxide (ZnO4) bonds. The transition (Tg), onset crystallization (Tx), crystallization (Tc) temperatures, and weight loss were identified from DSC and TGA findings, respectively. Also, the prepared glass shows good stability against crystallization, as reflected by (?T) variation. Furthermore, the radiation shielding parameter findings show good enhancement of the performance of the samples. However, upon these findings, one can say that these glasses could be used and utilized for radiation shielding purposes.

“…Nowadays, heavy metal oxide glasses have been used in several fields due to their favorite properties [14][15][16]. Moreover, transition metals (T M ) can be added during the preparation of the glass system to improve the optical, electrical and shielding properties of glasses [17][18][19], where the functions of the outer electron orbital in T M are very sensitive to the surrounding cations.…”

This work aims to study the influence of gamma irradiation on some bismuth borate glasses doped with different transition metal oxides (CuO, CoO, ZnO and CdO). The structure of the glass matrix was analyzed by Fourier transform infrared and ultraviolet-visible spectroscopy before and after gamma irradiation at doses of 1 kGy, 20 kGy and 50 kGy. Additionally, the attention is made in determining the attenuation parameters against gamma rays. Mass attenuation coefficient determined experimentally and calculated theoretically by WinXCom program, which is a significant program in the field of radiation shielding. It is found that the attenuation parameters of gamma ray have higher values of the sample without transition metal oxides and the other doped with CdO. From hardness measurements before and after irradiation, it was found that hardness increases with the addition of transition metal oxides to glass. The results of different techniques show that these glasses possess a slight effect on the network structure of the samples against gamma irradiation. So, it can be used in different applications of nuclear fields.
