The Se (AgX) ( = 0, 5 and X = Cl, Br, and I) glass-ceramics were synthesised melt-quenching, with density measured using Archimedes' principle. Radiation-shielding properties were investigated using across a range of 15 keV to 15 MeV, assessing parameters such as LAC, MAC, MFP, , , , , EABF, EBF, and FNRCS. The Se(AgBr) sample exhibited the lowest HVL, indicating superior photon attenuation compared to other compositions. The attenuation percentage (RPE%) was investigated experimentally across 60 keV, 81 keV, and 100 keV measured using Scanditronix stereotactic field diode (SFD) detectors. Additionally, their shielding performance was compared with commercially used materials, including ordinary concrete and radiation-shielding glasses. Results demonstrate that Se(AgBr) meets key shielding criteria, making it a promising alternative for low-energy radiation protection. Incorporating silver halides significantly influences shielding efficiency, with AgBr proving the most effective. These findings highlight the potential of AgBr-doped selenium glass-ceramics as efficient radiation-shielding materials, offering a viable replacement for traditional options in specific shielding applications.
通过熔融淬火法合成了Se(AgX)( = 0, 5且X = Cl、Br和I)微晶玻璃,使用阿基米德原理测量其密度。在15 keV至15 MeV的能量范围内研究了其辐射屏蔽性能,评估了诸如线性衰减系数(LAC)、质量衰减系数(MAC)、平均自由程(MFP)、 、 、 、 、等效原子序数(EABF)、等效电子数(EBF)和弗罗因德赖希近距离碰撞截面(FNRCS)等参数。Se(AgBr)样品表现出最低的半值层(HVL),表明与其他成分相比具有更好的光子衰减性能。使用Scanditronix立体定向场二极管(SFD)探测器在60 keV、81 keV和100 keV下对衰减百分比(RPE%)进行了实验研究。此外,还将它们的屏蔽性能与商业使用的材料进行了比较,包括普通混凝土和辐射屏蔽玻璃。结果表明,Se(AgBr)符合关键的屏蔽标准,使其成为低能辐射防护的有前途的替代品。掺入卤化银显著影响屏蔽效率,事实证明AgBr最为有效。这些发现突出了掺AgBr的硒微晶玻璃作为高效辐射屏蔽材料的潜力,为特定屏蔽应用中的传统选择提供了可行的替代方案。
