In a radiation image recording system in which a stimulable phosphor sheet is exposed to an imagewise radiation to record a latent image of a radiation image in the form of stored energy of radiation, the stimulable phosphor sheet is then exposed to stimulating rays to emit light according to the stored energy of radiation, and the emitted light is detected to obtain an image signal, light spontaneously emitted from the stimulable phosphor sheet upon exposure to the imagewise radiation is detected. Then, image processing data such as the maximum value, the minimum value and/or the average value of the stored energy level over the entire area of the image are calculated based on the amount of the light, and is recorded on the stimulable phosphor sheet or the cassette thereof. The image processing data are used for processing the image signal when recording a final image on a recording material.
