基于MCNP5与WINXCOM仿真计算的铋玻璃屏蔽特性研究
通过MCNP5(蒙特卡罗,MonteCarlo)和WINXCOM程序研究了在0.662MeV、1.17MeV和1.33MeV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2cm和10cm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。...

Methods: The mass attenuation coefficients of bismuth silicate glass were investigated with 7-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 mechanic |
