摘要
本文用蒙特卡罗方法计算了以水为介质的１５２Ｅｕ源几种能量的γ射线在不同体源厚度时的符合相加修正因子，同时用实验进行了验证。结果表明符合相加修正因子随样品厚度增大而逐渐减小，理论计算结果和实验测量结果在误差范围内基本一致。
In this paper, the coincidence summing correction coefficient for the γ ray of several energies of 152 Eu water source is calculated theoretically at different thicknesses of the body source using the Monte Carlo method. They are measured experimentally too. The results indicate that the coincidence summing correction coefficient reduces gradually with the increase of the sample thickness. The theoretical calculation results are almost identical to the experimental results within the error range. (
