摘要：
An ICP-MS analytical method as an alternative to the current radiochemical method was developed to analyze trace level Np-237 in bulk plutonium materials. In this method, Np-237 is determined together with a suite of trace elements during a single analysis using one dissolution solution. Method validation was achieved through precision examination, spike recovery study, detection limit determination, comparison of results with the radiochemical method, and laboratory intercomparison studies on Pu metals. The ICP-MS method significantly reduced the analysis cost, the sample amount, consumption of chemicals and waste generation, as well as the sample turnaround time.
