Abstract Objective To explore the effect of change in occupational internal dose coefficients on estimation of the internal exposure dose of radiation workers. Methods Forty-one radionuclides were selected as the research objects, and their new and old occupational internal dose coefficients were summarized. The change in internal dose coefficients was analyzed by calculating the ratios of dose coefficients and using the frequency distribution of ratios.Results The occupational internal dose coefficients of the 41 radionuclides analyzed had all changed, with ratios ranging from 0.1 to 4.5, and the maximum difference reaching 10 times (when the ratio was equal to 0.1).Conclusion It is recommended to revise the national standards concerning occupational internal dose coefficients in time and update the occupational internal dose coefficients, so as to better monitor the occupational health of radiation workers.
