探测超痕量Pu同位素在不同领域具有非常重要的意义。一种新的Pu同位素加速器质谱(AMS)测量方法被发展。两种~(239)Pu/~(240)Pu、~(239)Pu/~(242)Pu值分别为17.241和10.059的实验室参考标准、一个流程空白、一个商业空白、三个实际样品中的Pu同位素比值分别被用于AMS方法分析,测量
Detection of ultra-trace Pu isotopes in different fields has a very important significance. A new Pu isotope accelerator mass spectrometry (AMS) measurement method was developed. Two laboratory reference standards of 239 Pu / 240 Pu, 239 Pu / 242 Pu were 17.241 and 10.059, respectively. One process blank, one commercial blank, and three actual samples The Pu isotope ratios were used for AMS analysis and measurement, respectively
