摘要
Abstract
T he method w hich is used to determine uranium enrichment by deconvoluting complex peak clusters in 88-100 keV region of γ/X spectrum of uranium materials is the key technique of some uranium enrichment determination software ,such as MGAU , MGA + + ,etc .According to the basic principle of this method ,a code to analyze the spectrum was written ,in which peak shape model of γ/X ray was built to fit the spec-trum and efficiency fitting factor was developed to make efficiency correction . Two types of uranium samples with enrichment ranging from 1.80% to 90.1% were meas-ured by a HPGe detector and analyzed by the code . For the samples measured , the uranium enrichment was determined with relative deviation of about 2% for pellet and 1% for pow der samples .关键词
