Highly efficient gamma ray shielding glasses with chemical composition 39.5H₃BO₃–25TeO₂−15MO−10Na₂CO₃–10K₂CO₃−0.5Dy₂O₃ (M = BaO, CaO, SrO, Li₂O, ZnO) were synthesized by traditional melt-quenching technique. Physical, structural and elastic features of the glass systems were examined to prove the formation of bridging oxygens. The attributes such as optical basicity and ionic nature (I_c) clarifies that the glasses are inclined in the direction of ionicity rather than covalency. The γ-ray shielding parameters of the investigated glasses were calculated in an important range in radiation protection (0.015–15 MeV). At 0.02 and 0.03 MeV, the SrO containing glass (BTNKD-Sr) shows the highest μ/ρ values which is substituted by the BaO glass (BTNKD-Ba) thereafter. It signifies that BTNKD-Sr is the most effective material in shielding lower energy photons (up to 0.0374 MeV), while BTNKD-Ba indicates better shielding against photons in a wide energy region (0.0374–15 MeV). The half value layer (HVL) values of the prepared glasses range from 0.0163 cm for Li₂O glass (BTNKD-Li) to 0.0073 cm for ZnO glass (BTNKD-Zn) at 0.015 MeV, while the corresponding values range from 9.62 cm (BTNKD-Li) to 6.68 cm (BTNKD-Zn) at 15 MeV. The effective atomic numbers (Z_eff) of the glasses are rapidly decreased at 0.3 MeV.

高效伽马射线屏蔽玻璃，化学成分为 39.5H ₃ BO ₃ –25TeO ₂ -15MO-10Na ₂ CO ₃ –10K ₂ CO ₃ -0.5Dy ₂ O ₃ (M = BaO, CaO, SrO, Li ₂ O, ZnO)由传统的熔体淬火技术合成。检查了玻璃系统的物理、结构和弹性特征，以证明桥接氧的形成。光学碱度和离子性质等属性（I _c) 阐明玻璃倾向于离子性而不是共价性。在辐射防护的重要范围内（0.015-15 MeV）计算了所研究玻璃的γ射线屏蔽参数。在 0.02 和 0.03 MeV 时，含 SrO 的玻璃 (BTNKD-Sr) 显示出最高的 μ/ρ 值，此后被 BaO 玻璃 (BTNKD-Ba) 取代。这表明 BTNKD-Sr 是屏蔽较低能量光子（高达 0.0374 MeV）的最有效材料，而 BTNKD-Ba 表明对宽能量区域（0.0374-15 MeV）中的光子具有更好的屏蔽作用。制备的玻璃的半值层 (HVL) 值范围为 0.0163 cm，Li ₂O 玻璃 (BTNKD-Li) 在 0.015 MeV 下为 ZnO 玻璃 (BTNKD-Zn) 的 0.0073 cm，而相应的值范围从 9.62 cm (BTNKD-Li) 到 6.68 cm (BTNKD-Zn) 在 15 MeV。玻璃的有效原子序数 (Z _eff ) 在 0.3 MeV 时迅速降低。
