Abstract

This research was conducted to study x-ray and gamma radiation shielding parameters such as mass attenuation coefficient, mean free path, half value layer, tenth value layer, effective atomic numbers, effective electron density for the xBi2O3-(95-x)B2O3-5BaO (where x = 20 mol%, 35 mol%, 50 mol%, and 70 mol%) glass systems with different molar composition. The studied ceramic specimens were denoted by BB20, BB35, BB50 and BB70 and their density values were 4.438 g/cm3, 5.973 g/cm3, 7.156 g/cm3, and 8.005 g/cm3, respectively. Radiation shielding parameters of the samples were investigated by using web based XCOM programme. The obtained results revealed that the highest mass attenuation coefficients were reported for BB70 sample, which has the highest Bi2O3 additive in its chemical structure. At 7 MeV photon energy, half value layer (HVL) values were reported as 5.7812 cm, 3.8065 cm, 2.8533 cm, and 2.2457 cm for BB20, BB35, BB50 and BB70, respectively. Therefore, it can be concluded that the present bismuth sesquioxide based glasses in the Bi2O3-B2O3-BaO glass system have a good quality in radiation protection purposes. Therefore, this glass system can be used as an alternative to conventional materials with the right molar compositon in its chemical formation.

基于天然橡胶复合材料的类皮革材料

本文研究了不同摩尔组成的xBi2O3-(95-x)B2O3-5BaO (x = 20mol %， 35mol %， 50mol %和70mol %)玻璃体系的质量衰减系数、平均自由程、半值层、十值层、有效原子数、有效电子密度等x射线和伽马辐射屏蔽参数。所研究的陶瓷试样分别用BB20、BB35、BB50和BB70表示，其密度值分别为4.438 g/cm3、5.973 g/cm3、7.156 g/cm3和8.005 g/cm3。利用基于web的XCOM程序对样品的辐射屏蔽参数进行了研究。结果表明，化学结构中Bi2O3添加剂含量最高的BB70样品的质量衰减系数最高。在7 MeV光子能量下，BB20、BB35、BB50和BB70的半值层(HVL)值分别为5.7812 cm、3.8065 cm、2.8533 cm和2.2457 cm。由此可见，目前Bi2O3-B2O3-BaO玻璃体系中的倍半氧化铋基玻璃具有较好的防辐射性能。因此，这种玻璃系统可以作为传统材料的替代品，在其化学结构中具有正确的摩尔组成。
