Objective To analyze the diagnostic radiology equipment number, radiological staff structure, protection allocated at the medical institutes in Jiaxing city, with the purpose to provide basic data for the further optimization of resource allocation. Methods As required by the national radiation health monitoring program and using the stratified random sampling method , a total of 111 hospitals at grades Ⅲ, Ⅱ, Ⅰand other types were used to select 50% radiological institutions in Jiaxing. Unified questionnaires were used to investigate the basic situation in these hospitals, such as diagnostic radiology equipment, configurable protection equipment, radiation worker number and diagnostic frequency. Results The hospital number at grades Ⅲ, Ⅱ, Ⅰand other types accounted separately for 13.5%, 21.6%, 46.9% and 18.0% of the total. The equipment numbers for radiotherapy, nuclear medicine, interventional radiology and X-ray imaging at grade Ⅲ hospitals accounted for 100%, 100%, 57.9% and 38.0%, respectively, significantly higher than others. The numbers of conventional photofluorography and fluoroscopy equipment at grades Ⅰ hospitals accounted for 34.2% and 50%, slightly higher than others; CT and mammography devices were distributed at the grades Ⅱ and Ⅲ hospitals. The frequencies at X-ray diagnosis, CT diagnosis and interventional therapy and diagnosis, radiotherapy, and nuclear medicine diagnosis and therapy were 178.9, 157.5, 3.1, 1.5, 2.2 and 0.1 per thousand person-year in Nanhu district, which were higher than in the other areas of Jiaxing city. Conclusions Grade Ⅲ hospitals have more diagnostic radiology devices and radiation workers than in non-grade-Ⅲ hospitals. These hospitals were all equipped with adequate amount of protection equipment. The frequency of diagnostic radiology in Nanhu district hospital was significantly higher than that in other district hospitals.
