rough determination

In this work , a method is brought out to determine the uranium enrichment by analyzing the cdznte spectrum in 88 - 100kev region , through the y - rays and x - rays emitted from uranium isotopes and their daughters . a code is developed , and the method is verified through its analysis results
本工作通过对铀的cdznte能谱进行分析，提出了一种利用铀及其衰变子体在88 - 100kev能区的射线和特征x射线来粗略测定铀富集度的一种方法，并开发了能谱分析程序，通过分析结果初步验证了该方法的可行性。
