Zinc lead silicate glass system contains different amount of WO3 were fabricated using the classical melt-quench technique. The nature of the samples was investigated using X-ray diffraction. The ultrasonic velocities and elastic moduli were tested experimentally after that the results were compared by using the theoretical consideration. With increasing the WO3 content, decreasing the molar volume causes a decrease in the inter-ionic distance Ri. The FLUKA code were used to estimate the main attenuation considerations mass attenuation coefficients (MAC) and linear attenuation coefficients (LAC). The LAC increment from 0.728 cm-1 to 0.856 cm−1 as the WO3 concentration increment from 0 to 5 mol%, resulting in high shielding performance for G5. The dose rate at energy of 0.6 MeV with the G5 sample found to be declines from 2.35 × 107 R/h at 1 mm to 4.71 × 106 R/h at 4 mm. The values of mean free path (MFP) and the half value layer (HVL) are smaller than those of the traditional photon shields signifying that the fabricated samples (particularly G5) have interesting shielding characteristics to be used in applications involving x/gamma rays.

Pb3O4-SiO2-ZnO-WO3 玻璃的合成及其用于伽马屏蔽应用的基本特性

锌铅硅酸盐玻璃系统含有不同量的 WO 3是使用经典的熔融淬火技术制造的。使用X射线衍射研究样品的性质。对超声速度和弹性模量进行了实验测试,然后通过理论考虑对结果进行了比较。随着WO 3含量的增加,摩尔体积的减小导致离子间距离R i的减小。FLUKA 代码用于估计主要衰减考虑因素质量衰减系数 (MAC) 和线性衰减系数 (LAC)。LAC 增量从 0.728 cm-1 到 0.856 cm -1作为 WO 3浓度增加从 0 到 5 mol%,从而对 G5 产生高屏蔽性能。发现 G5 样品在 0.6 MeV 能量下的剂量率从1 mm 处的2.35 × 10 7 R/h下降到4 mm 处的 4.71 × 10 6 R/h。平均自由程 (MFP) 和半值层 (HVL) 的值小于传统光子屏蔽的值,这表明制造的样品(特别是 G5)具有有趣的屏蔽特性,可用于涉及 x/伽马射线的应用。
