Abstract
It is shown experimentally that a new x-ray phosphor Gb2O2S: Tb used as an intensifying screen with the common blue-sensitive x-ray photographic film can increase sensitivity to medical x rays by about a factor of 2 relative to CaWO4 which is currently used. It is also shown that a sensitivity increase of about 20 is possible if photographic film is optimized to the Gd2O2S: Tb emission.Keywords
