Method for erasing remaining radiation image

摘要

Disclosed is an improvement of a method for erasing a radiation image remaining in a stimulable phosphor sheet which has stored a radiation image and has been irradiated with stimulating rays to read the radiation image. The improvement comprises a first erasing step of irradiating the phosphor sheet with a first erasing light containing a light portion of wavelength in ultraviolet region; and a second erasing step of irradiating the phosphor sheet with a second erasing light containing no light portion of wavelength in ultraviolet region, said second erasing light and said first erasing light being employed in a ratio of amount of light in the range of 15/85 to 45/55. Devices for erasing radiation image appropriately employable in the above-mentioned method are also disclosed.
