<p>A method for recording and reproducing a radiation image comprising the steps of (i) causing a phosphor, which can be stimulated with visible or infrared radiations, to absorb a high energy radiation passing through an object, (ii) stimulating said phosphor with visible or infrared radiations to release the energy stored as fluorescent light, and (iii) detecting said fluorescent light with light detecting means, wherein the photostimulable phosphor is selected in the group consisting of green-emitting trivalent erbium activated barium ytterbium halides, trivalent erbium activated barium fluorohalides and solid solutions thereof, optionally comprising an alkali metal halide. Apparatus for recording and reproducing a radiation image using the above described method. Radiation image storage panel containing the above described photostimulable phosphors. Light-stimulable phosphors selected within the group consisting of green-emitting trivalent erbium activated barium ytterbium halides, trivalent erbium activated barium fluorohalides and solid solutions thereof, optionally comprising an alkali metal halide.</p> |
