Abstract Objective To investigate the occupational radiation protection status and influencing factors.Methods A total of 94 interventional radiation workers in a tertiary hospital in Shanghai were enrolled by using a self-administered questionnaire survey, and the survey data included information on workload, the use of personal protective equipment and auxiliary protective equipment, personal dose monitoring, occupational health examination, factors affecting the use of personal protective equipment.Results In 2017, the workload of cardiovascular, tumor and neurological interventional procedures were relatively large. The use rate of lead apron was 100%, followed by lead collar 97%, while the utilization rates of lead protective glasses, lead rubber caps and lead rubber gloves were only 52%, 23%, 10% and 3%, respectively. The usage rate of ceiling-suspension shields, table-suspension shields and mobile lead barriers were 84%,62% and 69%, respectively. The wearing rate of personal dosimeter was 78%, the number of staff wearing personal dosimeters inside and outside the lead clothing accounted for 49%. The rate of regular occupational health examination was 100%. The comprehensive utilization rate of personal protective equipment and auxiliary protective equipment and the wearing rate of personal dosimeter in tumor interventional workers were the highest. Unbalanced configuration of protective equipment and different awareness of protection were the main reasons for the difference in the use rate of personal protective equipment among different interventional radiologists.Conclusion The hospital should strengthen the construction of radiation safety culture, and further popularize the use of lead apron and auxiliary protective equipment.
