摘要:

用MCNP4C程序模拟计算20个水泥生料样品, 并用线性回归方法研究样品内热中子通量与元素特征γ射线间的关系. 计算结果表明, 利用二者之间的关系可准确计算热中子通量, 并提高了元素质量分数的测量精度.

关键词: &gamma, 射线, 水泥生料, 热中子通量, MCNP-4C

Abstract:

Twenty samples of cement raw material were calculated by MCNP4C code in order to find the relationship between the thermal neutron flux and the chara
cteristic γrays of main elements in sample. The relationship was determined by multiple linear regressions analysis. The result of the calculation shows that the relationship can be used to accurately calculate the thermal neutron flux and improve  the identification of the elements contents.

Key words: γray, cement raw material, thermal neutron flux, MCNP-4C
