Abstract

This work focuses on evaluating four glasses' radiation shielding ability, with compositions of (18+2x)BaO–17PbO₂-(65-3x)B₂O₃-xNd₂O₃ (where x = 0, 1, 2, and 3 mol%), using Phy-X at Eu-152 source-emitted energies. The glasses are designated as Ba18Nd0, Ba20Nd1, Ba22Nd2, and Ba24Nd3, each representing specific concentrations of components BaO and Nd₂O₃. Glass sample Ba18Nd0's gamma radiation transmission factor (TF) is studied at different thicknesses of 0.25, 0.75, and 1.25 cm, and the results show the TF to be close to zero at very low energy, thus indicating the lower energy photons to be almost completely absorbed by the glass sample. With a 0.25–1.25 cm glass thickness increase, the TF decreases, suggesting the glasses' improved radiation shielding ability. The radiation protection efficiency (RPE) was determined and found to have a positive relation with the glasses' density. In terms of the sample with higher BaO and Nd₂O₃ content (i.e., Ba24Nd3), there is a higher mean free path than for the other prepared glasses. The glasses' half-value layer (HVL) at 0.122 MeV is 0.10 cm, while with increased energy the HVL decreases to 0.725–1.14 cm at 0.296 MeV and 1.18–1.08 cm at 0.411 MeV.

掺钕硼酸钡玻璃成分与辐射屏蔽性能的关系

本工作着重于评估四种玻璃的辐射屏蔽能力，这些玻璃的成分为（18+2x） BaO-17PbO2 -(65-3x)B2O3-xNd2O3（其中x = 0,1,2,3 mol%），使用物理x在Eu-152源发射能量下。玻璃被命名为Ba18Nd0、Ba20Nd1、Ba22Nd2和Ba24Nd3，分别代表BaO和Nd2O3组分的特定浓度。研究了玻璃样品Ba18Nd0在0.25、0.75和1.25 cm的不同厚度下的γ辐射透射系数（TF），结果表明，在极低能量时，TF接近于零，表明较低能量的光子几乎完全被玻璃样品吸收。当玻璃厚度增加0.25 ~ 1.25 cm时，TF减小，表明玻璃的辐射屏蔽能力增强。测定了玻璃的辐射防护效率（RPE），发现其与玻璃密度呈正相关。对于BaO和Nd2O3含量较高的样品（即Ba24Nd3），其平均自由程高于其他制备的玻璃。在0.122 MeV时，玻璃的半值层（HVL）为0.10 cm，而随着能量的增加，在0.296 MeV时，HVL降至0.725 ~ 1.14 cm，在0.411 MeV时，HVL降至1.18 ~ 1.08 cm。
