Polymer Bulletin, 2026
This study developed novel EPDM rubber composites filled with tungsten powder as a safer alternative to radiation shielding materials. The composites rheological, mechanical, and radiation shielding properties were investigated. The results showed that adding tungsten powder up to 30 phr improved the composites’ mechanical properties and radiation shielding effectiveness. The tensile strength increased from 5.1 MPa (unfilled EPDM) to 16.5 MPa at 30 phr, with elongation at break rising from 750% to 1350%, and hardness from 48 to 73 Shore A. Under γ-irradiation, EPDM/W composites maintained superior stability, with 30 phr showing the highest resistance to degradation compared to other loadings. The linear attenuation coefficient increased with tungsten content, reaching 2.6 cm⁻¹ at 40 phr and 80.99 keV, and 0.1702 cm⁻¹ at 661.64 keV. The composites demonstrated promising properties for gamma-ray shielding applications, making them a potential candidate for replacing lead-based materials in nuclear facilities. The findings suggest that EPDM/W composites could provide a safer and more effective solution for radiation protection.

Journal of Nuclear Engineering and Radiation Science, 2025
The growing role of nuclear radiation in various domains necessitated a continuous development in enhancing the efficiency of radiation shielding materials. Generally, a shield that can attenuate thermal and fast neutrons and gamma rays simultaneously is the most effective in various applications. Therefore, in this article, a host glass of sodium silicate (labelled as BSiBi0) was reinforced by 10, 20, 30, and 40 mol. % of each of Bi and B ions simultaneously (BSiBi1, BSiBi2, BSiBi3, and BSiBi4, respectively) to produce an integrated shield capable of attenuating thermal and fast neutrons and gamma rays. To check the attenuation ability of the proposed glasses, fast neutrons removal cross section ΣF, thermal neutrons total macroscopic cross section ΣTh, total mass attenuation coefficients μm, linear attenuation coefficients μ, mean free paths (MFP), half-value layers (HVL), effective atomic numbers (Zeff), effective electron densities (Neff), and buildup factors for energy absorption (EABF) and exposure buildup factor (EBF) were studied extensively. Compared to the host glass (BSiBi0), the attenuation of gamma rays in the BSiBi4 glass (40 mol. % of each of Bi2O3 and B2O3) improved by 3.9–92.5% in the studied energy range, which extended to 100 GeV. At the same time, its ability to attenuate the fast neutrons enhanced by 86.0%, and thermal neutrons by 1402.4%. Hence, the BSiBi4 glass, with a composition of 20SiO2-40B2O3-40Bi2O3, was nominated as an efficient shield in relevant applications, such as hot cells, radiotherapy rooms, and the immobilization and disposal of radioactive wastes, due to its high attenuation ability for both neutrons and gamma rays.

A multi-function glass shield for neutrons and gamma rays of boron- and bismuth-reinforced silicate glass

Scientific Reports, 2024
A successful attempt to produce a multi-function glass shield for attenuating neutrons and gamma rays by reinforcing a silicate glass network with boron and bismuth has been accomplished. A composition of 20SiO2-80Na2O (BSiBi0) was proposed to be used as a host glass network and prepared using the melt/annealing techniques. The low concentration of SiO2 in BSiBi0 was not sufficient to form a stable glass network. Then, the proposed BSiBi0 was modified with 10, 20, 30, and 40 mol% of each of B2O3 and Bi2O3 (BSiBi1, BSiBi2, BSiBi3, and BSiBi4) simultaneously. The structural effects of adding B3+ and Bi3+ were studied through X-ray diffraction, density, and FTIR, which all showed enhancement of glass forming ability, a former role of Bi3+ ions, and crowded the glass network by BO4 units. The derived structural parameters $$-$$ - molar volume, mean silicon – silicon separation, mean boron – boron separation, oxygen packing density, packing density, and number of bridging/non-bridging oxygen $$-$$ - were extensively discussed to explore the impact of B3+ and Bi3+ on the formed network. The richness of the proposed host glass network by B3+ and Bi3+ enhanced its thermal stability. The obtained elastic properties by ultrasonic measurements reflect the increase of the glass rigidity with increasing concentrations of B3+ and Bi3+ ions. The obtained glasses have high visible light transparency and almost complete UV absorption. The measured shielding parameters against two types of neutron energies (total slow and slow) and a wide range of gamma rays’ energies showed a significant improvement in the shielding efficiency of the considered glasses. The total slow neutrons, slow neutrons, and gamma rays’ attenuation abilities were improved by 22.9, 135.5, and 73.8 $$-$$ - 199.5%. High thermal stability, elasticity, visible light transparency, and neutrons and gamma rays’ attenuation performance features give the produced glasses, especially BSiBi4 glass, preference as shielding materials in nuclear fields.

Radiation Protection Dosimetry, 2024
The development of radiation therapy necessitated a continuous R&D for radiotherapy rooms' glass windows to reach the highest levels of protection for the staff of the radiotherapy facility. Therefore, in this article, a novel type of lead borate glass depending on parallel augmenting of lead and boron was produced to be used as gamma-rays and fast and thermal neutrons barriers in radiotherapy rooms. Neutrons and gamma rays’ attenuation parameters, fast neutrons removal cross section ${\\varSigma}_R$, thermal neutron total cross section ${\\sigma}_T$, mass attenuation coefficient $\\sigma$, linear attenuation coefficient μ, half-value layer, mean free path, effective atomic number Zeff, effective electron density Neff, and buildup factor for energy absorption (energy absorption buildup factor) and exposure (exposure buildup factor) were studied extensively. Three tools, Phy-X/PSD, EpiXS and XCOM computer programs and the standard mixture rules were utilized to estimate the attenuation parameters. The improvement caused by the augmentation of lead and boron in both gamma rays and neutrons attenuation was evident from the obtained results. The glass containing the highest lead and boron concentration PbB5, 40Pb-50B, which is the most efficient attenuator for gamma rays and both thermal and fast neutrons was recommended to be a distinguished choice as a shield in a radiotherapy room.
