摘要

本研究通过测量光子能量在0.015 ~ 15.0 MeV之间的LAC值，研究了一系列硅溶胶晶体的辐射屏蔽性能。详细分析了化学成分，特别是SiO2重量百分比对这些晶体LAC值的影响。结果表明，材料的密度和SiO2含量对LAC值有显著影响。值得注意的是，LAC值随密度增加而增加，并与SiO2 wt%呈非线性三次关系，在约25% SiO2 wt%和E = 0.015 MeV时观察到最大衰减。这些发现表明，具有优化SiO2含量和密度的单硅酸盐晶体在先进的辐射屏蔽应用中具有很大的潜力。该研究为辐射防护材料的选择和设计提供了重要的见解，强调了成分控制对提高屏蔽效率的重要性。

Optimizing sorosilicate crystals for γ-ray shielding: Role of density and SiO2 content

This study investigates the radiation shielding properties of a series of sorosilicate crystals by examining their LAC values at photon energies of 0.015 to 15.0 MeV. Detailed analyses were conducted to explore the effects of chemical composition, particularly SiO₂ weight percentage, on the LAC value of these crystals. The results reveal that the LAC value is significantly influenced by both the density and the SiO₂ content of the materials. Notably, the LAC value increases with density and exhibits a non-linear cubic relationship with SiO₂ wt%, with maximum attenuation observed at approximately 25 % SiO₂ wt% and E = 0.015 MeV for the Hemimorphite crystal. These findings suggest that sorosilicate crystals with optimized SiO₂ content and density offer promising potential for advanced radiation shielding applications. The study provides crucial insights into the material selection and design for radiation protection, emphasizing the importance of compositional control in enhancing shielding efficiency.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
