New Gamma Scanning Technology for 200L and 400L Low and Intermediate Level Solid Waste

Abstract

Segmented gamma scanning (SGS) and tomographic gamma scanning (TGS) are two traditional detection techniques for low and intermediate level radioactive waste drum. However, detection accuracy of SGS is low and detection time of TGS is very long. This paper summaries three types of new gamma scanning techniques to assay the radioactive waste drum. Compared with SGS and TGS, these techniques exhibit the well-balanced performance which can improve the detection accuracy and shorten the detection time.
