摘要
使用蒙特卡罗方法模拟计算了一个用于4πγ计数的大体积阱式NaI(Tl)探测器的效率和能谱。采用一系列单能γ源标定探测器,对计算结果进行检验,其结果基本一致,两者间的最大偏差不超过±8%,证明计算结果是可靠的。
The efficiencies and energy spectra of a large volu me welltype NaI(Tl)detector which is used in 4πγ counting method are calculate d by using MonteCarlo method. At the same time, the detector is calibrated by using a series of single γenergy sources. The two results are in good agreeme nt, and the biggest discrepancy does not exceed ±8%. The calculated results are reliable.
