Abstract Objective To study the time distribution of radiation doses to Chinese public from atmospheric nuclear tests.Methods Based on the measured data of 90Sr annual deposition density in China from 1962 to 1987 by Health system,90Sr annual deposition data and methodology for calculating other radionuclides' deposition densities in UNSCEAR 2000 reports,we calculated annual effective doses to Chinese public from atmospheric nuclear tests using the new dosimetry model and parameters in UNSCEAR 2000 reports.Results Chinese public received the biggest doses in 1959 and 1963,0.203mSv/a and 0.202mSv/a.After 1963,doses to Chinese public were decreasing gradually and there was a little peak in around 1971 or so.Conclusion Time distribution of our results,radiation doses to Chinese public from atmospheric nuclear tests,were consistent with the global results in UNSCEAR 2000 reports on the whole.
