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, anddetecting the emitted light,in which said stimulable phosphor is a divalent europium activated complex halide phosphor having the formula (I):in which M" is at least one alkaline earth metal selected from the group consisting of Ba, Sr and Ca; M' is at 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 TI; 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 ≦ a ≦ 2,0 ≦ b ≦ 10-2, 0 ≦ c ≦ 10-2 and a+b+c≧10-6; and x and y are numbers satisfying the conditions of 0 < x ≦ 0.5 and 0 < y ≦ 0.2, respectively. A radiation image storage panel employed for the method is also disclosed.
