ICP-MS method for Pu and Np isotopes in population monitoring by a micro-flow injection sample introduction system

An ICP-MS method using a micro-flow injection (μ-FI) sample introduction system was developed for measuring 237 Np and 239,240,241 Pu in urine samples for sensitive and rapid population monitoring following a radiological or nuclear accident. Good selectivity from the chemical separation method allo...

Summary:An ICP-MS method using a micro-flow injection (μ-FI) sample introduction system was developed for measuring 237 Np and 239,240,241 Pu in urine samples for sensitive and rapid population monitoring following a radiological or nuclear accident. Good selectivity from the chemical separation method allowed the determination of 237 Np together with Pu isotopes using 242 Pu as a tracer. Significant improvements in ICP-MS sensitivity and detection limit were achieved using the μ-FI sample introduction and the desolvation techniques. The method developed has been successfully applied to a set of human urine samples spiked with Pu isotopes and a set of rat urine samples with metabolized Pu isotopes from research experiments. A micro-flow injection ICP-MS method was applied to radiological emergency monitoring of Plutonium and Neptunium.
