Abstract Objective To assess the personal dosage level of external exposure for radiation workers in yangpu. Methods Thermoluminescence dosimetry was applied to measure the personal external radiation dosage of workers exposed to radiation. Results Totally 2540 radiation workers were monitored from 2009 to 2012. The average annual effective dosage was 0.75 mSv/a. The workers receiving annual dosage equivalent less than 2 mSv accounted for 99.17%. The average annual individual effective dosage was higher in the nuclear medicine workers than those of other professions. Conclusion Most of the radiation workers in YangPu District are safe in the working conditions according to the related national standards. The radiation protection of nuclear medicine should be focused in the future.
