Abstract

Melt quenching technique was used to create Bismuth Boro-Silicate nano glasses with compositions of 45SiO-10CaO- 25NaO- xBiO- (20-x) BO (where x is 0, 5, 10, 15, and 20 mol %). Standard point sources AM-241, Ba-133, Co-60, Cs-137, and Eu-152 were used in the radiation experiment to evaluate the attenuation coefficients spanning the energy range of 59.51 keV to 1048.01 keV. The findings show that adding BiO in place of BO increases the following: radiation protection efficiency (RPE%), transmission factor (TF%), absorption buildup factor values (ABF), exposure buildup factor values (EBF), mass attenuation coefficients (MACs), linear attenuation coefficients (LACs), and radiation protection efficiency (RPE%). In comparison to lead glass, these findings demonstrate the potential of nano Bismuth Boro-Silicate glass as a radiation shielding material.

摘要

采用熔融淬火技术制备了组成为45SiO-10CaO-25NaO-xBiO-(20-x)BO（其中x为0、5、10、15和20摩尔%）的铋硼硅酸盐纳米玻璃。在辐射实验中使用标准点源AM-241、Ba-133、Co-60、Cs-137和Eu-152来评估能量范围为59.51keV至1048.01keV的衰减系数。研究结果表明，用BiO替代BO会增加以下各项：辐射防护效率（RPE%）、透射因子（TF%）、吸收积累因子值（ABF）、照射积累因子值（EBF）、质量衰减系数（MACs）、线性衰减系数（LACs）以及辐射防护效率（RPE%）。与铅玻璃相比，这些研究结果证明了纳米铋硼硅酸盐玻璃作为辐射屏蔽材料的潜力。
