| Abstract:: |
| Objective To analyze the abnormal dose monitoring result of radiation staff in medical institutions and provide a basis for standardizing the personal dose management of radiation staff in medical institutions. Methods Through the occupational radiation disease monitoring subsystem of the National Radiation Health Information Platform, 516 individual dose monitoring abnormal result of 410 radiation workers in a single monitoring period,which in 168 medical institutions under the 18 cities in Henan province were collected from 2020 to 2022 as research objects. Based on gender, age, length of service, occupational category, medical institution level, whether the dosimeter wearing standard, the abnormal result of radiation workers were grouped to analyze the influencing factors of individual dose monitoring result. Results The incidence of abnormal individual dose monitoring result in 2020-2022 was 6.83 × 10-3, 5.22 × 10-3 and 6.30 × 10-3, respectively. Abnormal results were mainly distributed in male radiology workers (66.83%), diagnostic radiology (59.51%) and interventional radiology (34.63%), tertiary (54.39%) and secondary medical institutions (36.34%). In the case of wearing personal dosimeter in a standard or irregular way,there were statistically significant differences in the incidence of abnormal outcomes between different levels of medical institutions and different occupational categories(χ2=14.42, 6.56, 32.96, 177.15, P<0.05).The median annual individual dose of radiology workers with " abnormal exposure dose" due to increased workload was 3.95 mSv, and the annual individual dose of interventional radiology workers was higher than that of radiotherapeutic workers (Z=5.07, P<0.05). Conclusions The education and training of radiological protection should be strengthened, and the wearing of individual dosimeters should be standardized; focus on the occupational exposure of interventional radiology staff, and take effective measures to reduce their exposure dose. |
