ABSTRACT:
In a radiation image recording system in which a radiation image is once recorded on a stimulable phosphor sheet and then read out and reproduced into a visible radiation image, a high-power light source is built in the system to erase the noise due to the previously stored radiation image and the fog in the phosphor sheet by a single erasing operation immediately before the phosphor sheet is to be used to record thereon a radiation image. The light source has an exposure amount of at least 500,000 1x.multidot.sec. and is positioned between a phosphor sheet feeding section and a section where a radiation image is recorded on the sheet. The system is also provided with a mechanism for sending the phosphor sheet from the recording section to a sheet receiver or radiation image read out and reproducing apparatus.
