A radiation image recording and reproducing method comprising steps of:n i) causing a divalent europium activated complex halide phosphor having the formula (I):n in which M II is at least one alkaline earth metal selected from the group consisting of Ba, Sr and Ca; each of X and X' is at least one halogen selected from the group consisting of Cλ, Br and I, and X = X'; X' is at least one halogen selected from the group consisting of F, Cλ, Br and I; and a, b and x are numbers satisfying the conditions of 0.1 ≦ a ≦ 10.0, 2×10 -5 ≦ b ≦ 2x10 -2 and 0 < x ≦ 0.2, respectively, to absorb a radiation having passed through an object or having radiated from an object; ii) exposing said stimulable phosphor to an electromagnetic wave having a wavelength within the range of 450 - 1000 nm to release the radiation energy stored therein as light emission; and iii) detecting the emitted light. A radiation image storage panel employed for said method is also disclosed. |
