    The constant exposure technique was applied to com-pare the radiographic image quality and relative speed of different fast radiographic systems. Conventional industrial X-ray films, exposed with lead intensifying screens, special fast film with fluorometallic screens as well as different brands of radiographic paper exposed both with fluorescent as well as fluorometalllic screens were tested and compared. ISO wire IQI's and ASTM penetrameters were used together with 30-mm aluminium and 10-mm steel plates. For all the fast radio-graphic systems wire sensitivity better than 2% was obtained. The constant exposure technique proved to be adequate for the assessment of fast radiographic systems.
