摘要
为了研究点源探测效率与空间探测位置之间的关系,采用蒙特卡罗计算方法模拟计算HPGe探测器对不同探测位置处点源152Eu、60Co及137Cs探测效率,并对计算结果进行数值拟合,确定了HPGe探测器对点源探测效率的函数及参数。
In order to study the relationship between the counting efficiency and the point sources position. The Monte Carlo code （MCNP） has used to calculate the counting efficiency of HPGe detector for standard γ- ray point sources in different vertical distances. For the 152Eu、60Co及137Cs point sources, the efficiency function of HPGe detector and its parameters for point sources has been determined by fitting the calculate dates.
