Abstrakt: An ICP-MS method using a micro-flow injection (m-FI) sample introduction system was developed for measuring 237Np and 239,240,241Pu 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 237Np together with Pu isotopes using 242Pu 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.
