摘　　要：空气中^(210)Pb、^(210)Bi和^(210)Po的活度浓度不仅决定于自身的衰变,还与气溶胶的干湿沉降有关,三者之间处于不平衡状态。目前国内暂无气溶胶中^(210)Pb测量方法相关标准,通过^(210)Pb、^(210)Bi和^(210)Po三者之间的关系可以确定气溶胶^(210)Pb的测量方法。介绍了气溶胶^(210)Pb常用5种分析方法,通过探测下限的比较,分析了各种分析方法的特点。The activity concentration of ^210Pb, ^210Bi and ^210Po in air is not only determined by radioactive decay, but also related to the dry and wet deposition of aerosol. There is a radioactive disequilibrium. At present there is no standard method to measure ^210Pb in aerosol. Utilizing the relationship between ^210Pb, ^210Bi and ^210po can measure ^210Pb in aerosol. This paper introduced five commonly used methods. The characteristics of each analytical methods were summarized though the comparison of the detection limit of each method.
