Objective To observe the personal radiation doses of radiology workers in a hospital in Shanghai.
Methods Thermoluminescence dosimetry method was adopted to record the personal doses of radiology workers in a Shanghai hospital from 2000 to 2011. A total of 1 200 person-time were recorded.
Results The annual average personal effective doses ranged from 0.22 mSv/a to 0.44 mSv/a during the selected 12 years, and the median of the average values was 0.25 mSv/a. The highest annual average effective dose was found in the nuclear medicine technologists (0.52 mSv/a). All the annual average effective doses estimated in the current study were lower than the national limits and the average radiation level of Shanghai or China.
Conclusion The annual average effective doses of radiology workers in the hospital are under the limit of individual dose stipulated by natioanl standard.
