４．１０γ能谱法非破坏性测定Ｐｕ同位素丰度（Ｉ）唐培家，吴昕，刘大鸣，王思广钚是重要的核材料之一，核保障监督和核燃料循环中物料衡算都需要对其进行精确的测定。符合中子计数法是常用的测定钚含量的方法之一，但需要准确知道样品中钚的同位素组成。质谱法和放射化...
Non-Destructive Determination of Pu Isotopic Abundance by γ-Spectrometry (I) TANG Peijia, WU Xin, LIU Daming, WANG Siguang Plutonium is one of the important nuclear materials. Both nuclear safeguards and materials accounting in nuclear fuel cycle need to be accurate The determination. Complying with the neutron counting method is one of the commonly used methods for the determination of plutonium, but requires accurate knowledge of the isotopic composition of plutonium in the sample. Mass Spectrometry and Radiochemistry ...
