A method of estimating residence time of atmospheric aerosol (RTAA) is established based on the relationship between specific activity ratio of radon daughters in atmospheric particles and average life of the particles. The method is further testified in a standard radon chamber. When specific activity of radon is 1.816 kBq/m3 in the chamber,the RTAA is estimated to be 112.17 min,which is in agreement with the mean-ventilation time in the chamber,104.17 min. Therefore,the residence time of the atmospheric aerosol can be estimated by using the specific activity ratios of radionuclide in the same decay chain,such as 214Bi/214Pb, 210Bi/210Pb and 210Po/210Pb.
