核材料中杂质元素的数量很多,不同厂家生产的核材料中杂质的含量各不相同,因此可以利用核材料中杂质元素的含量这一特性参数追溯核材料的来源。由于铀的发射光谱谱线复杂,铀的存在会对其它元素的测量产生光谱或基体干扰,因此在进行测量之前,需将铀与其它杂质元素分开。本
Since the amount of impurity elements in nuclear materials is very large and the content of impurities in nuclear materials produced by different manufacturers varies, it is possible to trace the origin of nuclear materials by using the characteristic parameters of the content of impurity elements in nuclear materials. Due to the complexity of the emission spectrum of uranium, the presence of uranium can cause spectral or matrix interference with the measurement of other elements, so uranium needs to be separated from other impurity elements before the measurement. this
