摘要

Analysis of plutonium in environmental samples is one of the measures recently included in international safeguards. Plutonium and some other actinides, and fission and activation products in environmental samples, are currently used as indications of undeclared nuclear activities. Two destructive assays are presented for determination of ~(238)Pu and ~(239+240)Pu in environmental samples. Alpha spectrometers were utilized to identify the isotopic composition of plutonium. The results show coincidence of the determined plutonium concentrations with certified values. The U test was used as a quality control indicator of the presented procedures and results. The levels of ~(238)Pu and ~(239+240)Pu in the samples ranged from 1.6 x 10~7 to 4.2 x 10~8 atoms, and from 2.2 x 10~(10) to 2.6 x 10~(11) atoms, respectively. Both methods could be applied for accurate, low level analysis to indicate plutonium origin.
