摘要
硼酸盐玻璃体系是用熔淬法制备的。XRD 被用来确认样品的非晶态结构,FTIR 被用来观察振动模式,UV-Vis-NIR 分光光度计被用来测量透射光谱。通过 FLUKA 蒙特卡洛模拟、XCOM 程序和实验方法对辐射屏蔽性能进行了检验。随着 BaO 含量的增加,密度增大,而摩尔体积减小。对于 X 射线和伽马射线辐射,表明添加 BaO 而不是 B2O3 可提高屏蔽性能,而对于热中子辐射,Σ 则有所降低。结果表明,添加 BaO 增强了 X 射线和伽马射线的屏蔽性能。然而,加入 BaO 会降低玻璃样品的热中子屏蔽能力。这些数据可用于任何需要高效光子或热中子屏蔽的应用。
Photon and thermal neutron shielding behaviors of aluminum calcium fluoroborate glass modified with barium oxide: FLUKA Monte Carlo, XCOM and experimental investigations
The borate glass system was prepared using the melt-quenching method. The XRD was used to confirm the amorphous structure of present samples, the FTIR was utilized to observe vibration modes, and the UV–Vis-NIR spectrophotometer was employed to measure transmittance spectra. The radiation shielding properties were examined by FLUKA Monte Carlo simulation, XCOM programs, and experimental methods. The density increased, while the molar volume decreased as the BaO content increased. For the X-ray and gamma-ray radiation, indicate that the addition of BaO instead of B2O3 improve the shielding properties, while the Σ is decreased for thermal neutron radiation. According to the results, adding BaO enhanced the X-ray and gamma-ray shielding properties. However, adding BaO led to the reduces its ability of shielding the thermal neutrons of the glass samples. These data are expected to be accommodate to considering for any applications which requires high efficiency of photon or thermal neutrons shielding.
期刊介绍:
Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
