摘　　要：提出环境样品中210Po的分析方法:对环境水样采用直接蒸发银片自沉积法;对其他环境样品(如土壤、稻谷),采用硝酸和H2O2进行湿法氧化处理后,在盐酸体系中银片自沉积法。叙述了样品前处理、分离、制源以及测量等程序。分析结果表明,该方法能应用于环境介质中210Po的分析测定。Methods of determination of 21op rect evaporation-spontaneous deposition us o in environmental samples were presented, that is, the died for treatment of natural waters, and wet oxidation treatment with HNO3 and H2 O2-spontaneous deposition by silver in hydrochloric acid system used for other environmental samples （such as soil, rice）. The sample preparation, separation, source preparation and measurement procedures were described. The analysis results showed that the methods can be applied to measurement of 210Po in environmental materials.
