| Abstract:: |
| Objective To analyze the dose range distribution of abnormal result, the distribution of occupational categories, the incidence of abnormal result of different occupational categories, the causes of abnormal result and the factors influencing abnormal values, on the basis of investigated abnormal result of individual monitoring for occupationally external exposure, in order to provide the scientific basis for the formulation of the relevant regulations and standards and the hospital radiation protection management. Methods The abnormal result of 389 radiation workers in medical institutions receiving annual individual doses each exceeding 1.25 mSv, reported in 2017 in 19 provinces, were collected and analyzed. Results Dose distribution range of abnormal result were mainly between 1.25 and 5 mSv; diagnostic radiology workers accounted for the highest fraction, 59.64% of the totals; and interventional radiology workers had the highest incidence, 4.17‰ of abnormal result. The abnormal result was mainly caused by improper wearing or operating personal dosimeters; the abnormal values in the eastern regions were higher than those in other regions, with a median of 6.41 mSv; the abnormal values in the cause-unknown group was higher than those in other groups, with a median of 10.32 mSv. Conclusions The publicity and training of radiation protection knowledge should be further strengthened to improve the protection awareness of radiation workers. The occupational exposure of interventional radiology workers should receive special attention. |
