There has been an increasing number of research and development activities focusing on the use of different glass systems for their nuclear radiation shielding features. In this study a simulation study has been carried out at a wide photon energy region in order to investigate the radiation protection feature of bismuth borate glasses. This study has been conducted to evaluate the proficiency level of six different glass systems (70-x)B2O3 + xBi2O3 + 15ZnO + 15Na2O (where x = 0, 5, 10, 15, 20 and 25 mol%) exposed to photon, charged particle (H1) and (He+2) and neutron. For this investigation, transmission factors (TF), mass attenuation coefficient (MAC), half value layer (HVL), tenth value layer (TVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff) have been computed. The results confirm that the parameters of the examined glasses MAC, HVL, TVL, MFP, Zeff, and Neff are associated with photon energy and chemical composition. In addition, neutron effective cross-sections (∑R) have been computed for bismuth borates and it was seen a good harmony. The computations for present samples have been examined over a broad energy range from 0.01 to 20 MeV and theoretical results have been obtained by using MCNPX software for transmission factors. In addition, simulation results have been calculated with the WinXCom program. Furthermore, MSP and PR calculations of the bismuth borate glass have been performed to figure out the radiation shielding features. For that reason, the SRIM code has been used to simulate H1 and He+2 particles. Considering the results obtained from this research, which examines the radiation protection of bismuth borate glasses, indicates that the best shielding achievement (while the HVL, TVL, MFP, TF have the lowest and the highest (∑R) values) is reached at 25% Bi2O3. As can be seen in the results, the addition of bismuth affirms that the use of such glass systems improves the radiation protection feature. In particular, 25%Bi2O3 glass system has been proved to show superior shielding properties for gamma radiation in combination with charged particles. Since the glass sample with the highest bismuth additive is 25%Bi2O3, the most radiation protection effect is also seen in this example. The obtained material has a satisfactory radiation shielding property as bismuth is added to the mixture.

硼酸铋玻璃体系对核辐射屏蔽参数影响的研究

越来越多的研究和开发活动集中于使用不同的玻璃系统来实现其核辐射屏蔽功能。在这项研究中,为了研究硼酸铋玻璃的辐射防护特性,已经在较宽的光子能量区域进行了模拟研究。进行了这项研究以评估六种不同玻璃系统(70-x)B 2 O 3  + xBi 2 O 3  + 15ZnO + 15Na 2 O(其中x = 0、5、10、15、20和25 )的熟练水平mol%)暴露于光子,带电粒子(H 1)和(He +2)和中子。对于此调查,传输因子(TF),质量衰减系数(MAC),半值层(HVL),十分值层(TVL),平均自由程(MFP),有效原子序数(Zeff),有效电子密度(Neff) )已计算。结果证实了所检查眼镜的参数MAC,HVL,TVL,MFP,Z eff和N eff与光子能量和化学成分有关。另外,已经计算出硼酸铋的中子有效截面(∑R),并且观察到良好的和谐。目前样品的计算已在0.01至20 MeV的宽泛能量范围内进行了检查,并使用MCNPX软件获得了传输因子,从而获得了理论结果。此外,已经使用WinXCom程序计算了仿真结果。此外,已经进行了硼酸铋玻璃的MSP和PR计算,以找出辐射屏蔽特征。因此,已使用SRIM代码来模拟H 1和He +2粒子。考虑到这项研究检查硼酸铋玻璃的辐射防护的结果,表明在25°C时达到了最佳屏蔽效果(而HVL,TVL,MFP,TF的最低值和最高(∑R)值) %Bi 2 O 3。从结果中可以看出,添加铋肯定了这种玻璃系统的使用改善了辐射防护功能。特别是,已证明25%Bi 2 O 3玻璃系统与带电粒子结合使用时,对伽玛射线显示出优异的屏蔽性能。由于铋含量最高的玻璃样品为25%Bi 2 O 3,在此示例中也看到了最大的辐射防护效果。当将铋添加到混合物中时,获得的材料具有令人满意的辐射屏蔽性能。
