To protect the occupational health and safety of 131I nuclear therapy workers and increase the utilization rate of 131I nuclear therapy，131I nuclear therapy workplaces in 10 hospitals in Shenzhen were selected in this study. The iodine box filter membrane sampling method，combined with a low background high-purity germanium γ energy spectrometer and passive efficiency calibration software，was used to measure the 131I activity concentration in critical areas of nuclear medicine workplaces. The accumulated effective dose of occupational personnel was estimated，and then the radiation safety risk of occupational personnel was evaluated. Furthermore，the effect of the correction factor change of 131I nuclide treatment operation on the radiation safety risk of occupational personnel was analyzed. The results showed that when the correction factor of 131I (liquid) nuclide treatment operation mode was set to 10，the radiation safety risk was far below the standard limit for manufacturer delivery and automatic packaging in nuclear medicine workplaces. It was recommended that the correction factor of the operation model of 131I (liquid) radionuclide therapy be distinguished by the packaging system，with manual packaging set to 1 and manufacturer delivery and automatic packaging set to 10.
