Radiation image conversion method and radiation image conversion panel using therefor

Abstract

Abstract PURPOSE:To carry out the radiation image conversion in high sensitivity, using a fluorescent material having high luminance and exhibiting accelerated phosphorescence, by exposing a specific fluorescent material exhibiting accelerated phosphorescence to radiation, exciting the fluorescent material with electromagnetic wave, and detecting the emitted fluorescent light. CONSTITUTION:Radiation transmitted through the object to be photographed or emitted from the object is absorbed in a fluorescent material of formula (MI is Li, Na, K, Rb or Cs; MII is Be, Mg, Ca, Sr, Ba, etc.; MIII is Sc, Y, La, Ce, Pr, etc.; X, X' and X'' are F, Cl, Br or I; A is BeO, MgO, Al2O3, Sio2, Nb2O5, etc.; B is Eu, Tb, Ce, Tm, Dy, etc.; 0<=a<0.5; 0<=b<0.5; 0<c<0.5; 0<d<=0.2) exhibiting accelerated phosphorescence. The fluorescent material is excited with electromagnetic wave consisting of visible light and/or infrared radiation to effect the emission of the radiation energy stored in the fluorescent material. The emitted fluorescent light is detected to effect the radiation image conversion.
