Abstract::
      Objective To investigate the current status of radiodiagnostic and radiotheraputic resources and the frequency of medical radiation exposure in order to provide basic data for reasonably allocating medical resource and standardizing meical exposure.Methods According to data available from the Jiangsu Radiation Health Information Management Platform in 2020 and the total number of permanent residents from Wuxi Statistical Yearbook 2019, a statistical analysis was carried out of the staff and equipment and the frequency of medical radiation exposure in Wuxi mecical institutions.Results There were 923 items of radiodiagnostic and radiotheraputic equipment, 2 480 medical radiation workers in Wuxi city in 2020, which were estimated to be 140.03 items of equipment and 376.24 workers per 106 population. The frequency of X-ray diagnosis and treatment were 1 137.53 procedures per 103 population, including 646.17 per 103 population for conventional X-ray diagnosis, 394.11 per 103 population for CT scan, 5.34 per 103 population for interventional radiology, 0.79 per 103 population for radiotherapy and 7.12 per 103 population for nuclear medicine. Interventional radiology, radiotherapy and nuclear medicine was mainly concentrated in tertiary hospitals.Conclusions The number of radiodiagnostic and radiotheraputic resources in Wuxi is above the national and provincial level, although in a unbalanced state. Conventional X-ray diagnosis frequency in Wuxi is higher than that of provincial level, resultsing in higher collective dose. Radiological diagnosis and treatment activities needs a approach to the process of justification.
