The absolute efficiency of phosphor screens under x-ray excitation is studied for tube voltages ranging from 20 to 60 kV. The screens were prepared of ZnS:Cu, ZnCdS:Ag, Y/sub 2/O/sub 2/S:Tb, Gd/sub 2/O/sub 2/S:Tb, and CaWO/sub 4/, which are the phosphors most commonly used in the x-ray applications. This efficiency appears to be about 100 times lower than the efficiency of the same screens under fluoroscopy conditions.
