| 摘 要： | 经过同位素示踪实验,研究了酸度、时间、体积、温度、还原剂对210Po自沉积的影响,以及气溶胶预处理的条件实验,得出了最佳实验条件,对实际气溶胶样品中210Po进行了分析测定,全程化学回收率在94.0%～103%,平均值为(98.1±5.5)%。太原地区冬季气溶胶中210Po的活度浓度范围为1.21～1.53 mBq/m3,平均值为(1.31±0.08) mBq/m3。

| Abstract: | Through the isotopic tracer experiments, influences of acidity, time, temperature and reductant in the self-deposition were studied as well as the pretreatment condition of aerosol, with the optimal experimental conditions derived at last. This method has been applied to determine 210Po in real aerosol samples with a full recovery of 94.0%—103% and an average value of (98.1±5.5)%. 210Po aerosol concentration of Taiyuan city in winter is 1.21—1.53 mBq/m3, its average value is (1.31±0.08)mBq/m3. |
