Abstract Objective To understand and master the status of radiation diagnosis and treatment as well as their development in Xuzhou City, to provide data basis for the rational allocation and supervision of radiation diagnosis and treatment, and to promot the rational development of radiation diagnosis and treatment.Methods Taking all radiation diagnosis and treatment institutions in Xuzhou as the survey object, using the letter and visit investigation method to carry out the survey.Results A total of 314 institutions were surveyed in Xuzhou City, both the number of device and radiation workers increased in 2013-2015, but the number of radiation workers for each piece of device did not obviously changed, and the regional distribution of device was uneven. The total frequency of medical uses of radiation was in the upward trend, with the fastest growth in nuclear medicine treatment. The frequency of X-ray diagnosis was highest in the Grade I and other hospitals, while radiotherapy, interventional radiology and clinical nuclear medicine were mainly concentrated in the Grade Ⅲ hospital.Conclusion The medical radiation resources increased year by year, but their regional distribution was uneven. The total frequency of medical uses of radiation also increased year by year, but the overall level was still much lower than the economically developed regions such as southern Jiangsu. Controlling the medical exposure to radiation workers and public and enhancing their protection have become the main tasks of radiological health supervision.
