介绍了应用γ扫描装置对可燃废物中的铀含量无损测定的研究成果。通过对仪器的刻度、本底实验、γ点源实验、加入标准样品实验等,确定了该方法的探测下限为每包废物中~(235)U含量0.053g。当每包废物中~(235)U的含量达到1g时,方法误差为±36％(2σ);当每包废物中~(235)U的含量达到5g时,方法误差为±20％(2σ);经过三个月的考验,方法的长期稳定 The research results of nondestructive determination of uranium content in combustible waste by γ scanning equipment are introduced. The limit of detection for this method was determined to be 0.053 g of ~ (235) U per pack of waste by calibrating the instrument, background experiment, γ point source experiment and adding standard sample experiment. The error of the method is ± 36% (2σ) when the content of ~ (235) U per pack reaches 1g; the method error is ± 20% when the content of ~ (235) U in each pack of waste is 5g ); After three months of tests, the long-term stability of the method
