    摘要： In a radiation image recording and reproducing method for storing a radiation image on a stimulable phosphor sheet, exposing the stimulable phosphor sheet to stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the stored radiation energy, photoelectrically detecting the emitted light to obtain an electric image signal, and reproducing a visible image by use of the electric image signal, the detection is conducted in such a condition that the level of an instantaneous light emission after-glow signal representing an instantaneous light emission after-glow released by the stimulable phosphor sheet after it is exposed to a radiation to have the radiation image stored in the stimulable phosphor sheet is not higher than 10 -3.5 time the level of a stimulated light emission signal representing the light emitted by the stimulable phosphor sheet exposed to stimulating rays in proportion to the stored radiation energy.
