ABSTRACT:
A radiation image recording and reproducing method comprises the steps of scanning a stimulable phosphor sheet carrying a radiation image stored thereon with stimulating rays, and detecting light emitted by the stimulable phosphor sheet upon stimulation by stimulating rays to obtain an image signal. The image signal including a stimulated light emission signal and an after-glow signal representing a stimulated light emission after-glow emanated by the portion of the stimulable phosphor sheet no longer being exposed to stimulating rays is detected in such a condition that the level of the after-glow signal at a position on the stimulable phosphor sheet 20 mm beyond the position where exposure to stimulating rays is completed is not higher than 10.sup.-2.5 times the level of the stimulated light emission signal, and the level of the after-glow signal at a position 430 mm beyond the position where exposure to stimulating rays is completed is not higher than 10.sup.-3.3 times the level of the stimulated light emission signal.
