ABSTRACT:
A radiation image recording and reproducing method which is improved in efficiency of erasure and comprises steps of:
(i) causing a radiation image storage panel containing a divalent europium activated barium fluorohalide stimulable phosphor to absorb a radiation having passed through an object or having radiated from an object;
(ii) exposing the panel to stimulating rays to release the radiation energy stored therein as light emission;
(iii) detecting the emitted light; and
(iv) exposing the panel to light having a wavelength at least within the stimulation wavelength region of the phosphor to erase the radiation energy remaining therein,
in which said stimulating rays are electromagnetic waves having a wavelength within the range of 640-900 nm.
