ABSTRACT
@#<b>Objective</b> To investigate the current status of application of resources on medical exposure in Dongying, China, and to provide fundamental data for setting up the health information management system of occupational radiation diseases and implementing health supervision and management strategies. <b>Methods</b> According to the requirements of monitoring program on radiation health of Dongying in 2021, a general survey was carried out in all medical institutions (other than dental clinics) providing radiodiagnosis and radiotherapy services by the field investigation method using the unified questionnaires and survey content, and a descriptive analysis was conducted on the results. <b>Results</b> There were 92 institutions of radiodiagnosis and radiotherapy in Dongying, 1112 radiation workers who accounted for 5.9% of all workers on duty, including 679 (61.1%) males and 433 (38.9%) females, and 364 pieces of radiation equipment, including 339 for X-ray diagnosis, 8 for radiotherapy, 2 for nuclear medicine, and 15 for interventional radiology. The allocation of personal protective equipment for interventional radiology staff in tertiary hospitals was higher than that in secondary hospitals, in which there were 0.36 and 0.23 pieces of lead-rubber aprons, 0.43 and 0.30 pieces of lead-rubber hats, 0.50 and 0.35 pieces of lead-rubber collars, 0.05 and 0 pairs of lead-rubber gloves, and 0.31 and 0.17 pairs of lead protection glasses per capita, respectively. The allocation rates of lead-rubber collars and lead protection glasses in the nuclear medicine staff were higher than those in the interventional radiology staff, with 0.63 collars and 0.88 pairs per capita, respectively. The annual frequency of medical exposure was calculated to be 864.3 person-times per 1000 population for radiodiagnosis and 5.2 patients per 1000 population for radiotherapy. <b>Conclusion</b> The allocation and application of resources on medical exposure in Dongying is unbalanced, so it is demanded to set up a health information management system of occupational radiation diseases for continuously mastering the application of medical exposure and adopting differentiated regulatory measures such as rating classification in Dongying.
