Simultaneous Analyses of ²¹⁰Pb, ²¹⁰Bi and ²¹⁰Po in Aerosol Using Sr Resin

The activity concentration of ²¹⁰Pb, ²¹⁰Bi and ²¹⁰Po in air is radioactive disequilibrium. In this paper, the method of joint analysis was designed about these three radionuclides, and was proved by being used standard solution. The technique is proved to be feasible for Pb-Bi-Po separation by Sr resin. The separation effect of these radionuclides is most satisfactory by the recovery of ²¹⁰Bi(about 97%)>²¹⁰Po(about 93%)>²¹⁰Pb(about 89%), and the growth curve of PbSO₄, and the decay curve of BiOCl. The application of research about joint analyses of ²¹⁰Pb, ²¹⁰Bi and ²¹⁰Po in aerosol using Sr resin can explore the Pb-Bi-Po imbalance in the aerosol, providing technical support for aerosol source identification.
