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.

Key words: recovery, 210Po, self-deposition, aerosol
