Summary: Research on protection techniques against harmful effects of gamma radiation has increased recently. Developing radiation-resistant materials with high radiation resistance and absorption capability for different types of ionizing radiation shows promise. This study presents the preparation and examination of a novel polymer doped with various concentrations of WO3 for radiation shielding. The experimental results demonstrate the effectiveness of the polymer's radiation shielding characteristics and provide insights for predicting similar shielding properties.

Summary: This research prepared new types of mortar and evaluated the impact of WO3 and barite on their radiation shielding performance and mechanical properties. The results showed that adding a high percentage of WO3 significantly improved the radiation shielding performance of the mortar. Additionally, the thickness of the mortar samples needed for comparable photon attenuation and radiation protection was calculated, and it was found that thinner samples could provide similar protection as thicker samples.

Summary: Bismuth borosilicate glasses doped with increasing concentration of TeO2 were synthesized and their shielding properties for gamma radiation were analyzed. The study also investigated the thermoluminescence intensity and kinetic parameters. Results showed that higher concentrations of TeO2 and CeO2 incorporation led to increased thermoluminescence intensity and trap center density.

Summary: The radiation attenuation ability of Bi2O3 powder in different sizes was investigated. It was found that the linear attenuation coefficient of micro-sized Bi2O3 is higher than that of nano-sized Bi2O3 when they have the same mass, and the difference between the two samples decreases with increasing photon energy. The mass and thickness required to reduce the initial photon intensity by half were also reported.

Summary: In this study, new Cr-based alloys were fabricated using the conventional solid-state reaction method. The gamma ray shielding performance of these alloys was experimentally explored, showing a good agreement between experimental and theoretical data. The radiation protection efficiency of the alloys ranged from 0.184 to 0.81 MeV, with the chemical composition affecting the half value layer (HVL) values. Replacing CrTe alloy with Sb resulted in an increased linear attenuation coefficient (LAC) value.

Summary: This paper experimentally evaluated the radiation shielding properties of ball clays produced with different percentages of micro and nano ZnO. The results showed that ball clay with nano ZnO had a higher linear attenuation coefficient (LAC) and a slightly lower half-value layer (HVL) compared to ball clay with micro ZnO. This suggests that ball clay with nano ZnO is more effective in attenuating radiation in limited spaces.

Summary: This study investigates the possibility of using nano-lead oxide (nPbO) as a modifier agent in alkali-activated slag (AAS) mortar. Different ratios of nPbO were added to the mortar, and the effects on various properties were studied. The results showed that introducing nPbO improved the flowability, mechanical strength, aging resistance, and radiation properties of the AAS mortar. Suitable ratios of nPbO can enhance the performance of the mortar and expand its applications.

Summary: In this research, polymers were fabricated by combining polyester, boron oxide, and tellurium oxide. The radiation protection features of these polymers were examined, and the results showed that the linear attenuation coefficient decreased with increasing energy. The addition of tellurium oxide significantly increased the linear attenuation coefficient at low energy. Moreover, the increase in tellurium oxide content led to a decrease in the half value layer and an improvement in the effective atomic number of the polymers.
