Abstract: Objective To investigate the personal dose level of external irradiation among radiation workers in a hospital in Nantong City. Methods The rmoluminescence method was used to monitor the personal external radiation doses of radiation workers in the hospital from 2014 to 2021.The radiation doses received by radiation workers of different occupational categories were analyzed. Results The collective effective dose of the hospital in 8 years was 556.7 person·mSv and the average annual effective dose was 0.59 mSv/a.The highest annual effective dose was among the occupational categories of interventional radiology and nuclear medicine.The difference of annual effective dose in different occupational categories was statistically significant(H=232.520,P<0.05). Conclusions The average annual effective dose of radiation workers in the hospital is in accordance with the relevant national standards.It is necessary to strengthen the dose supervision of interventional radiology and nuclear medicine workers.
