ABSTRACT:
A radiation image conversion panel is made of a stimulable phosphor which stores radiation energy when exposed to a radiation and emits light when stimulated by visible light or infrared rays. The panel is subjected to excitation before it is exposed to a radiation for recording or storing a radiation image therein by exposing the panel to light having a wavelength within the range of stimulating light wavelength of the stimulable phosphor used in the panel. By exciting the panel before exposure to radiation, the energy of radiation stored therein which will cause a noise is removed therefrom.
