| Abstract:: |
| Objective To analyze the levels of individual doses to radiation workers receiving medical radiation exposure in hospitals in Jiangxi province, so as to provide reference for radiation protection. Methods The radiation workers of different types in medical institutions in Jiangxi were investigated from 2014 to 2018, involving diagnostic radiology, radiotherapy, nuclear medicine and interventional radiology. Statistical analyses were made of the individual doses to medical radiation workers in the province. Results The total number of monitored workers were 23 833 with average annual individual effective dose of 0.316 mSv. NR1 and NR5, the ratios of the number of workers receiving annual individual doses exceeding 1 and 5 mSv to the total monitored workers were 4.32% and 0.10%, respectively. During the five-year period, the average annual individual effective dose showed a upward and then downward trend, with peak appearing in 2017. A total of 17 909 diagnostic radiologists were monitored, accounting for 75.14% of the total number of monitored workers. The average annual individual effective dose received by workers was 0.329 mSv, the highest, in interventional radiology, followed by diagnostic radiology 0.318 mSv, nuclear medicine 0.283 mSv, and radiotherapy 0.269 mSv, respectively. There were statistically significant differences among radiation workers of different types (χ2=489.39,P<0.001 ). Conclusions The average annual individual effective dose to the radiation workers in medical institutions in Jiangxi province meets the relevant national standards, but with an upward trend in nuclear medicine. The higher levels of individual doses to radiation workers are seen in primary and secondary hospitals. It should be strengthen the oversight of radiation workers in nuclear medicine and in primary and secondary hospitals. |
