Objective: To analyze the personal dose of radiation exposure of radiation workers in some medical institutions in Tianjin, and to provide reference for radiation protection work. Methods: Using cluster sampling method, 8718 radiation workers from some medical institutions (including tertiary, secondary and first-level hospitals) in Tianjin from 2014 to 2018 were selected as the subjects of investigation. Monitoring data were collected, analyzed and evaluated. Results: From 2014 to 2018, a total of 8718 persons were monitored, with 14 persons (0.2%) whose annual effective dose was higher than 5 mSv; 8661 persons (99.3%) whose annual effective dose was lower than 2 mSv; 43 persons (0.5%) whose annual effective dose per capita was the highest in diagnostic radiology, which was 0.22 mSv; the annual effective dose per capita of radiation workers in primary and secondary hospitals was higher than that in tertiary hospitals; and the abnormal rate of individual dose monitoring was 73. Personnel, accounting for 0.8% of the total number of monitored personnel; the annual effective dose changes of the four types of radiation workers monitored from 2014 to 2018 showed a downward trend, and the annual effective dose of the four types of radiation workers in 2014 was the highest. Conclusion: Personal dosage of radiation workers in some medical institutions in Tianjin is at a low level, and attention should be paid to diagnostic radiology workers.
