摘要
Abstract
Uranium enrichment is recognized as a significant target of verification in nuclear safeguards.A method for uranium enrichment determination by analyzing gamma peaks of 235U,238U and 228Th (daughter of 232U) to calibrate relative detection efficiency was described.A code to verify the method by analyzing the spectrum was written.A HPGe detector was used to measure two types of uranium samples with enrichment ranging from 1.8％ to 90.2％ repeatedly.For the samples measured,the uranium enrichments are determined with an accuracy of about 3 ％.关键词
