Abstract: A simultaneous determination method of 210Pb, 210Bi and 210Po in rock and soil by α,β particle counter method after enrichment of 210Bi and 210Po by nickelplated sheet was proposed. By the optimization and selection of acidity, volume, temperature and reducing agent for solution preparation, the possible interference of coexisting elements and isotopes were eliminated effectively. The selfplating time was shortened to 40 min. Under the optimal conditions, the calibration curves of 210Po, 210Bi and 210Pb were established with correlation coefficient in the range of 0.998 30.999 7. The linear range was 1.0×1031.0×102 Bq. The detection limit of 210Po,210Bi,210Pb was 6×10-4 Bq/g,6×10-3 Bq/g and 6×10-3 Bq/g,respectively.The precision of method (RSD, n=11) was better than 1.6 %. The recoveries of standard addition were 95 %105 %. The proposed method realized the simultaneous and rapid determination of 210Pb, 210Bi and 210Po in rock and soil.
