44143CANlA Method for Recording and Reproducing a Radiation Image, Panel and Phosphors for Storing a Radiation Image ABSTRACT OF DISCLOSURE A method for recording and reproducing a radiation image comprising the steps of (i) causing a visible or infrared radiation stimulable phosphor to absorb a high- energy radiation passing through an object, (ii) stimu- lating said phosphor with visible or infrared radiation to release the stored energy as fluorescent light and (iii) detecting said fluorescent light with light detect- ing means, is characterized by the fact that the photo- stimulable phosphor is selected within the group of rare earth orthosilicates activated with a first activator comprising cerium and/or terbium and a second activator comprising zirconium and/or samarium, wherein rare earth is one of a) yttrium, b) yttrium and lutetium and c) yt- trium, lutetium and gadolinium. Panel for storing a radiation image containing the above described photostimulable phosphors. Phosphors selected within the group of rare earth orthosilicates activated with a first activator compris- ing certium and/or terbium and a second activator com- prising zirconium and/or samarium, wherein rare earth is one of a) yttrium, b) yttrium and lutetium and c) yttri- um, lutetium and gadolinium.
