摘要:
A radiation image recording and reproducing method comprising steps of: i) causing a radiation image storage panel to absorb a radiation having passed through an objector having radiated from an object, the radiation image storage panel containing a divalent europium activated barium fluorobromide phosphor showing a stimulation spectrum in which the emission intensity at the stimulation wavelength of 500 nm is higher than the emission intensity at the stimulation wavelength of 600 nm; ii) exposing said radiation image storage panel to an electromagnetic wave having a wavelength within the range of 400 - 550 nm, the wavelength of 550 nm being exclusive, such as Ar ion laser beam to release the radiation energy stored therein as light emission; and iii) detecting the emitted light.
