Radiation image information detecting panel and radiation image information read-out system

A radiation image information read-out system comprising a radiation image information detecting panel provided with a radiation absorbing phosphor layer including phosphors which absorb radiation and emit light according to the amount of the radiation, a stimulable photoconductive layer which generates electron-positive hole charges in an amount according to the amount of light and stores and records a radiation image information by trapping the charges while releasing the trapped charges upon exposure to stimulating light, a pair of photocurrent detecting electrode layers which are permeable to light and are respectively provided on upper and lower surfaces of the stimulable photoconductive layer to detect the released charges, and a panel-like light source for projecting the stimulating light onto the stimulable photoconductive layer, and

• an image signal obtaining means which obtains an image signal carrying thereon image information by controlling the panel-like light source to cause the stimulating light to scan the stimulable photoconductive layer and detecting the charge released from the stimulable photoconductive layer in response to exposure to the stimulating light as a photocurrent by way of the photocurrent detecting electrode layers.
