Abstract
In a radiation image recording and reproducing method in which a radiation image is once recorded in a stimulable phosphor and then read out and reproduced into a visible image, noise developing in the visible image due to repeated use of the stimulable phosphor is effectively erased by the combined use of first and second erasing steps. The first erasing is conducted to erase the radiation image previously stored in the phosphor, which requires a long period to erase, at an appropriate point of time after the phosphor is once used. The second erasing is carried out quickly to erase the fog, which develops in the phosphor after the first erasing, immediately before the phosphor is to be used for the next radiographic operation.
