Objective: The basic status of quality control of apparatus of radio diagnosis and radiotherapy in Beijing were mastered to promote and guide the radiation protection work efficiently. Methods: 110 devices of radio diagnosis and radiotherapy from 38 typical medical institutions were selected as the research object, and their key performances were determined and tested by using the appropriate surveying instruments, then they were evaluated according to the national related technical criterions and protection standards. Results:The initial total qualified rate of the 110 sets of radio diagnosis and radiotherapy apparatus was 79.1%, and the initial qualified rates for radio diagnosis equipment, radiotherapy equipment and nuclear medicine equipment (PET and SPECT) were 82.5%, 70.8%and 66.7%respectively. The total qualified rate of all the devices was 95.5%after being debugged and rechecked. The local practical quality control conditions of radio diagnosis and radiotherapy can be reflected from the 38 medical institutions and their medical radiation equipments surveyed in Beijing. Conclusion:The initial examination of performances of the 110 medical radiation devices in Beijing is not optimistic, it is very necessary to strengthen the quality control testing of radio diagnosis and radiotherapy devices.
