Objective To assess the personal dosage level of external exposure for radiation workers in Jinhua．
Methods Thermoluminescence dosimetry was applied to measure the personal external radiation dosage of workers exposed to radiation in Jinhua during 2008-2011.
Results Totally 799 radiation workers were monitored from 2008 to 2011. The collective annual dosage equivalent was 854.70 man mSv and the average annual effective dosage was 1.07 mSv/a. The workers receiving annual dosage equivalent less than 5 mSv accounted for 98.12%. The average annual individual effective dosage was higher in the interventional radiology workers than in other work types, and the numbers of interventional radiology workers monitored increased every year.
Conclusion Most of the radiation workers in Jinhua city are safe in the working conditions according to the related national standards. The interventional radiology workers should be a key population for radiation prevention.
