Abstract :
Recognizing the importance of quality assurance in radiotherapy and the need to make access to radiation standards traceable to the international measurement system to every radiotherapy center, the KFDA, as a national secondary standard dosimetry laboratory, has started a quality audit program in 1999. This program was initiated by tele-survey to all radiotherapy centers regarding general information about their radiotherapists, medical physicists, type of equipment, dosimeters, etc. This provided the KFDA with a data file and led to links between the KFDA and the clinics. A quality assurance network was set up and on-site dosimetry reviews were arranged according to a suitable timetable. Usually, the outputs of radiotherapy units at given conditions were measured with Farmer-type ionization chambers and compared with corresponding values quoted by the radiotherapy centers
