				        	Objective The rapid development of radiation equipment has put forward higher requirements for protective facil -ities.The aim of this study was to research the radiation protection status of treatment equipment room in thirty -three medical units from East China area , and to put forward corresponding countermeasures to improve the level of radiation protection . Methods The li-cense and archival of X-ray machine, CT, gamma knife, accelerator, after loading therapy machine were surveyed in the thirty-three medical units .The engine room size , wall thickness , lead equivalent of protection doors , and leakage level of equipment were detec-ted.All the data were evaluated and analyzed on the basis of the corresponding national standards . Results ①The inspection pass rates of radiation treatment equipments in the first class hospitals were afterloader (100%), X-ray apparatus(99%), gastrointestinal machine(98%), CT(98%), medical processing accelerator (98%), gamma knife(97%), DSA(94%), PET-CT(94%), ECT (90%), dental engine(84%)and molybdenum target drone (84%).The inspection pass rates of radiation treatment equipments in other class hospitals were medical processing accelerator (100%), X-ray apparatus(91%), CT(89%), gastrointestinal machine (80%), DSA(80%) and (80%) gamma knife.②The qualified rates of the leakage radiation levels of radiation therapy , diagnostic radiology and nuclear medicine were 100%, 99% and 97%. Conclusion The radiation protection of treatment equipments and facilities in thirty-three medical units from East China area needs to be strengthened . We should strengthen supervision , implement the rules and regulations , strictly perform the regulation of radiation protection evalua-tion, and strengthen the training of radiation protection regulations and skills .
