Godechal, J. Delhove, C. Mambour, J. Coomans, A. Wambersie] In the frame of a quality assurance programme in diagnostic radiology, carried out in Belgium between 1989 and 1993, systematic measurements were performed to check the performance characteristics of X ray units in routine operation, both in public hospitals and in private practices. Measurements were performed at 226 X ray units (conventional and mobile units) and 30 mammography units. The dose rate at the image intensifier was also measured at 177 units (71 surgical units and 106 conventional units). The major shortcomings which were observed were related to: (1) The tube tension; for 15% of the units, at 70 kV, the displayed tension and measured tension differed by more than 10%. (2) The filtration: inadequate filtration was noticed in 6% of the units. (3) The dose rate at the image intensifier: the tolerance limit of 1 µGy.s-1 was exceeded in 41% of the mobile surgical units over 10 years old, and in 25% of the conventional units.
