Abstract

To achieve more efficient and accurate measurement of low- and intermediate-level radioactive waste (LILW), a room-temperature semiconductor detector CdZnTe (CZT) can be used to replace the high-purity germanium detector. The traditional method cannot identify nuclides since the energy resolution of CZT detectors is poor, and the spectrum have more overlap** peaks, compared with HPGe detectors. Therefore, in this study, we proposed a gamma spectrum analysis method based on an intelligent dynamic library. Simulation spectrum experiment and standard-source spectrum experiment achieved LILW all-nuclide quantitative analysis based on a CZT detector for the first time globally.
