ABSTRACT:
A stimulable phosphor member for recording and reproducing a penetrating radiation image is disclosed, comprising at least one phosphor layer containing in a binder a mixture of two or more individually prepared divalent europium doped bariumfluorohalide phosphors at least one of which contains (a) co-dopant(s) which co-determine(s) the character of the stimulation spectrum of the co-doped phosphor, whereby the method of recording and reproducing said penetrating radiation image comprises the steps of (i) causing stimulable storage phosphors to absorb said penetrating radiation having passed through an object or emitted by an object and to store energy of said penetrating radiation, (ii) stimulating said phosphors with stimulating light to release at least a part of said stored energy as fluorescent stimulation light and (iii) detecting said stimulation light.
