Abstract

Lithium aluminoborate glasses modified with alkaline earth oxides were investigated to evaluate their radiation shielding performance following earlier structural and physical characterizations. The mass attenuation coefficient (MAC) was theoretically determined using both Phy-X and WinXCom software, with consistent agreement observed between the two methods. Additional shielding parameters, including half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), and effective atomic number (Zeff), were also calculated. The prepared glasses demonstrated relatively low HVL, TVL, and MFP values, indicating effective attenuation of ionizing radiation. The fast neutron removal cross-section (FNRCS) was further evaluated and compared to reported data for glass systems, ordinary concrete, graphite, and other conventional shielding materials. Within the studied series, Ba-modified glasses exhibited favorable γ-ray shielding characteristics, whereas Sr-modified glasses provided the highest FNRCS values, underscoring their potential as promising candidates for neutron shielding applications.

碱性和混合碱性铝酸锂玻璃的辐射屏蔽性能

在先前的结构和物理表征之后，研究了用碱土氧化物修饰的铝酸锂玻璃，以评估其辐射屏蔽性能。采用Phy-X和WinXCom两种软件对质量衰减系数（MAC）进行了理论上的测定，两种方法的结果一致。计算了半值层（HVL）、十值层（TVL）、平均自由程（MFP）和有效原子序数（Zeff）等附加屏蔽参数。制备的玻璃显示出相对较低的HVL、TVL和MFP值，表明电离辐射的有效衰减。研究人员进一步评估了快中子去除截面（FNRCS），并将其与玻璃系统、普通混凝土、石墨和其他传统屏蔽材料的报告数据进行了比较。在研究的系列中，ba改性玻璃表现出良好的γ射线屏蔽特性，而sr改性玻璃提供了最高的FNRCS值，强调了它们作为中子屏蔽应用的有希望的候选者的潜力。
