The determination of ultra-trace plutonium is very important in different fields.A new measurement method of plutonium isotopic ratios with accelerator mass spectrometry(AMS)was developed at China Institute of Atomic Energy(CIAE).Two laboratory reference standards of ~(239)Pu/~(240) Pu(ST1)and ~(239)Pu/~(242) Pu(ST2)are17.241and 10.059,a flow blank,a commercial blank and three real samples were respectively
