材料属性的研究,是核取证学应用于核材料归因的重要基础。通过核材料属性的研究,解决核材料来源的问题。核材料的同位素丰度和杂质是核材料的核心属性之一。通过对来自同一铀浓缩生产线的不同级联段的铀产品进行同位素和杂质测量,使用MC-ICPMS(多接收电感耦合等离子体质谱)测定样品的~(234)U/~(238)U、~(235)U/~(238)U和~(236)U/~(238)U同位素比,使用Q-ICP-MS(四极杆电感耦合等离子体质谱)根
The study of material properties is an important basis for applying nuclear evidence to nuclear material attribution. Through the study of the properties of nuclear materials, we can solve the problem of sources of nuclear materials. The isotopic abundance and impurities of nuclear materials are one of the core attributes of nuclear materials. The isotope and impurity measurements of uranium products from different cascade sections of the same uranium enrichment production line were carried out using MC-ICPMS (multi-inductively coupled plasma mass spectrometry) to determine the ~ (234) U / ~ (238) U, ~ (235) U / ~ (238) U and ~ (236) U / ~ (238) U isotope ratios were determined by Q-ICP-MS
