摘　　要：用γ能谱法和放射化学法对大气气溶胶中^(210)Pb的活度浓度进行测定,对比分析结果,γ能谱法能够满足大气环境气溶胶中^(210)Pb的常规监测。用γ能谱法对成都地区大气气溶胶中^(210)Pb活度浓度进行了为期两年的采样监测,年平均浓度为1.50 m Bq/m^3,浓度变化有明显的季节性特征,冬季高夏季低。Gamma ray spectrometry method and radiochemical method were introduced to measure the radioactivity concentrations of ^210pb in aerosol of Chengdu. Result of the two analytical methods were compared. Gamma ray spectrometry method can meet the routine monitoring of ^210Pb in atmospheric aerosol. From 2015 to 2016, the radioactivity concentrations of ^210Pb in aerosol of Chengdu were determined by Gamma ray spectrometry method. The annual average concentrations of ^210Pb were 1.50mBq/m^3. The radioactivity concentrations reflected obvious seasonal trends. The ^210Pb levels were higher in winter and lower in summer.
