%X 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 nickel-plated 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 self-plating 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 3-0.999 7.The linear range was 1.0×10-3-1.0×102 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.
