RADIATION IMAGE RECORDING AND REPRODUCING METHOD AND RADIATION IMAGE STORAGE PANEL EMPLOYED FOR THE SAME

摘要

A radiation image recording and reproducing method comprising steps of: causing a stimulable phosphor to absorb a radiation having passed through an object or radiated by an object, exposing said stimulable phosphor to an electromagnetic wave having a wavelength within the range of 450-800 nm to release the radiation energy stored therein as light emission, and detecting the emitted light, in which said stimulable phosphor is a divalent europium activated complex halide phosphor having the formula (I): MIIFX.aMIX'.bM'IIX''2.cMIIIX'''3.xA:yEu2+(I) in which MII is at least one alkaline earth metal selected from the group consisting of Ba, Sr and Ca; MI is a least one alkali metal selected from the group consisting of Li, Na, K, Rb and Cs; M'II is at least one divalent metal selected from the group consisting of Be and Mg; MIII is at least one trivalent metal selected from the group consisting of Al, Ga, In and Tl; A is at least one metal oxide; X is at least one halogen selected from the group consisting of Cl, Br and I; each of X', X'' and X''' is at least one halogen selected from the group consisting of F, Cl, Br and I; a, b and c are numbers satisfying the conditions of 0/=10-6; and x and y are numbers satifying the conditions of 0
