[Intensifying screens: speed, definition, afterglow and abrasion resistance (author's transl)].
Main characteristics of radiological intensifying screens were measured. Speed and definition under conditions described before. The different screens-film systems were ranged after their speed factor, at 40, 70 and 120 kV with mention of definition of these systems when measured. Afterglow and abrasion resistance were measured under experimental well definite conditions. Results show that are extant rare earth screens allowing a decrease of X-ray exposure without too great afterglow or mechanical frailty.
