层析γ扫描技术是桶装中低放核废物无损分析技术的主要分析方法,能够准确测量桶装容器内中、高密度非均匀核废物中的核素及其含量。本文综述了国内外桶装核废物层析γ扫描技术研究现状,简述国内现有研究基础和研究进展,并对层析γ扫描技术的发展趋势作了简要分析。提出了层析γ扫描技术研究发展方向和我国桶装核废物层析γ扫描技术面临的问题,并对所面临问题提出了相应的对策。
Tomographic Gamma Scanning is the main analytical method of nuclear waste in dram Non - Destruc- tive - Assay. It can accurately measure the nuclides of the non - uniform nuclear waste with middle or high den- sity in the drum. This paper reviews the research status of Tomographic Gamma Scanning of nuclear waste in drum at home and abroad, summaries the domestic researches at the existing basis and the progresses made, and gives a brief analysis of Tomographic Gamma Scanning's development trend. Research and development di- rection of Tomographic Gamma Scanning and the domestic problems faced by Tomographic Gamma Scanning of nuclear waste in drum are summarized, and solutions to these problems are briefly offered.
