As one of impurities,Th is needed to be determined for control quality of Pu product.Due to the high radioactivity and fatal toxicity of Pu,it is very difficult to measure the micro Th in Pu product.It is necessary to develop a sensitive method for determining the micro Th in Pu under the described harsh condition.
