摘要
介绍了无源效率刻度方法的原理,利用HPGeγ谱仪,通过标准点源和体源测量对实验室无源效率刻度方法(LabSOCS)进行了验证。实验表明,无源效率刻度方法的拟合结果是可以接受的,可作为效率计算方法和实验室质控方法的一个补充,同时分析了无源效率拟合的影响因子。
In this paper,the source-free efficiency calibration method is used to verify the HPGe γ-spectrometer.A 60Co standard point source and three body sources were used in the efficiency calibration with the LabSOCS code.The results show that this method can be used as a supplement method to efficiency calculation and laboratory quality control.Meanwhile,the impact factors of source-free efficiency fitting were analyzed.
