摘要
Abstract
The YAP∶Ce scintillator was selected as a core component for the instru‐ment , and a contact‐type measurement of micro and trace plutonium α activity in solution was established . The results show that under the aqueous phase plutonium solution concentration from 5.20 × 10-5 g/L to 1.30 × 10-3 g/L ,the concentration of plutonium and net count rate have fine linearity (R2 = 0.987 7) ,and the quantitative detection limit is 5.20 × 10 -5 g/L .Under the organic phase plutonium solution concen‐tration from 2.27 × 10-5 g/L to 1.13 × 10-3 g/L ,the net count rate and the concentra‐tion of plutonium have fine linearity (R2 =0.992 3) ,and the quantitative detection limit is 2.27 × 10 -5 g/L .The method is different from the traditional α‐counting method ,and has the advantages of simple and convenient operation and without complicated sample preparation process .It is expected to provide a new way for micro and trace plutonium determination online or in laboratory in spent fuel reprocessing .关键词
