摘要

通过MCNP 5（蒙特卡罗

Monte Carlo）和WINXCOM程序研究了在0.662 MeV、1.17 MeV和1.33 MeV三种γ射线下铋玻璃的衰减系数

并与铅玻璃进行对比。根据衰减倍数K以及综合考虑材料屏蔽性能和机械性能后

材料可以选择含氧化铋含量为50%的铋玻璃。计算了137Cs与60Co源照射以及铋玻璃的厚度分别为2 cm和10 cm的水模体剂量率分布。结果反应出在适合的能量下

铋玻璃可能会替代铅玻璃作为防辐射玻璃。

Abstract

Background: Currently

lead glass is widely used as observation window

while lead is toxic heavy metal. Purpose: Non-toxic materials and their shielding effects are researched in order to find a new material to replace lead containing material. Methods: The mass attenuation coefficients of bismuth silicate glass were investigated with γ-ray’s energy at 0.662 MeV

1.17 MeV and 1.33 MeV

respectively

by MCNP 5(Monte Carlo) and WINXCOM program

and compared with those of the lead glass. Results: With attenuation factor K

shielding and mechanical properties taken into consideration

bismuth glass containing 50% bismuth oxide might be selected as the right material. Dose rate distributions of water phantom were calculated with 2-cm and 10-cm thick glass

respectively

irradiated by 137Cs and 60Co in turn. Conclusion: Results show that the bismuth glass may replace lead glass for radiation shielding with appropriate energy.
