| Abstract:: |
| Objective To understand the monitoring levels of individual dose to radiation workers in Jiangsu province from 2011 to 2018, and to analyze their changing trends. Methods Through National Individual Dose Registry, the data on the monitoring result of occupational external exposure of radiation workers in our province was collected, and statistical analysis was performed. Results A total of 176 134 radiation workers in Jiangsu province were collected from 2011 to 2018. The annual collective effective dose was 58 man·Sv and the average annual effective dose was 0.35 mSv. The average annual effective doses to medical radiation workers for interventional radiology and nuclear medicine were both 0.41 mSv, with significantly higher NRE ratios than others (χ2=219.1, P<0.05 ). By 2018, the numbers of monitored workers were 25 714 for medical radiation, accounting for 81%, with an average annual effective dose of 0.24 mSv, and 6 169 for industrial radiation, accounting for 19%, with an average annual effective dose of 0.18 mSv. Conclusions The average annual effective dose to radiation workers in Jiangsu province is in consistency with the relevant national standards. The dose values for radiation workers in interventional and nuclear medicine are relatively high. The protection measures in their workplace should be improved. Meanwhile oversight of radiation protection should be enhanced for individual radiation workers in Jiangsu province. |
