模拟土壤中γ放射性核素活度浓度测量比对

摘要

本文介绍了本实验室采用效率曲线法和ISOCS模拟法刻度γ谱仪，并对模拟土壤进行了γ放射性核素活度浓度的测量比对工作，获得的结果与参考结果的相对偏差相比均小于20％，验证了2种方法均能满足测量要求，同时能够达到比对目的。%This paper introduces the efficiency calibration and ISOCS measurement method .The work of inter-comparison on Simulated soil was completed .The inter-comparison results showed that the relative deviation between measurement results and reference values was less than 20%according with the acceptance .
