Abstract Objective To understand and analyze the individual dose level of occupational external exposure of medical radiation workers in Yunnan province from 2015 to 2017 and to provide the data and scientific basis for the prevention and control of occupational radioactive disease in this province.Methods According to the methods of the Specifications for Individual Monitoring of Occupational External Exposure (GBZ 128-2016), the Thermoluminescent Dosimeter(TLD) System was used to detect the external exposure dose of medical radiation workers, and the individual dose monitoring results were collected and analyzed statistically.Results 8,776 radiological works were monitored from 2015 to 2017. The average annual individual effective dose was 0.313 mSv/a, among which the occupational category with the highest annual effective dose was nuclear medicine (2C) and the highest value 0.388 mSv/a was found in 2017. SPSS was used for comparison between groups, and the difference was statistically significant (P<0.001).Conclusion The average annual individual effective dose of radiation workers in medical system in Yunnan is within the dose limit of the national standards. To protect their occupational health, it is recommended that the individual monitoring of external exposure for nuclear medicine(2C) staff be given priority.
