SET OF RADIATION INTENSIFYING SCREEN

摘要

PROBLEM TO BE SOLVED: To provide a set of intensifying screen that makes it possible to obtain radiographs with high sensitivity and high sharpness. SOLUTION: A set of radiation intensifying screen is a pair of a sheet of front intensifying screen and a sheet of back intensifying paper with phosphor layers where phosphors are scattered in a resin formed on a support body respectively. A fluorescent dye or a fluorescent pigment that absorbs a part of the emitted light from the phosphors and emits the light whose wavelength is different from it is contained in a part of the phosphor layers of the front/ back intensifying screen. Moreover, the support body of the front intensifying screen is made of a light reflecting support body and that of the back intensifying screen is made of a light absorbing support body.
