通过实验检验了ISOCS无源效率刻度在就地测量中的准确性。对于饱和圆柱体模型，ISOCS刻度效率与实测效率在低、中、高能量区的偏差分别小于7％、5％和3％。对于不饱和墙体，通过ISOCS效率刻度计算所得核素活度与实验室采样测量结果在低、中、高能量区的偏差分别小于13％、3％和2％。结果表明，ISOCS无源效率刻度方法在一定偏差范围内是可接受的。

It is verified that the accuracy of ISOCS efficiency calibration without a radioactive source in situ measuring by the experiment is adequate .For saturated body source model , the efficiency deviation between ISOCS calibration and actual measured at low , medium and high energy are respectively less than 7%,5%and 3%.For unsaturated wall , the nuclide activity deviation between ISOCS efficiency calculation and laboratory sampling measurement in low , medium and high energy are respectively less than 13%, 3%and 2.2%.The results show that ISOCS efficiency calibration method without a radioactive source is acceptable within a certain range deviation .
