摘要:
A method for recording and reproducing a radiation image comprising the steps of (i) causing a visible radiation stimulable phosphor to absorb a high-energy radiation passing through an object, (ii) stimulating said phosphor with visible radiation to release the stored energy as fluorescent light and (iii) detecting said fluorescent light with light detecting means, is characterized by the fact that the photostimulable phosphor is selected within the group of divalent europium activated alkali earth metal halosilicates.Apparatus for recording and reproducing a radiation image using the above described method.Panel for storing a radiation image containing the above described photostimulable phosphors.Phosphors selected within the group of alkali earth metal halosilicates activated with divalent europium in the presence of Al and/or Ga and/or Na and/or K.
