In this paper,the equivalent radius of radioactive sources in each segment is determined by analyzing the different responses of the two identical detectors,and an improved segmented gamma scanning is used to assay waste drums containing mainly organic materials,and proved by an established simulation model.The simulated radioactivity distributions in homogenous waste drum and an experimental heterogeneous waste drum were compared with those of traditional segmented gamma scanning.The results show that our method is good in performance and can be used for analyzing the waste drums. 展开更多
