Abstract:
A radiation image conversion panel comprising,(i) a phosphor sheet which contains a support having thereon a stimulating light absorbing layer (A) being colored to absorb the stimulating light, and a stimulable phosphor layer in order; and (ii) a protecting layer which covers the stimulable phosphor layer of the phosphor sheet, wherein the protective layer comprises a stimulating light absorbing layer(B) being colored to absorb the stimulating light, and the layers(A) and (B) each have a smaller absorbance at a peak wavelength of a stimulated emission than an absorbance at a peak wavelength of the stimulating light, and a thickness of the layer(A) is larger than a thickness of the layer(B); further comprising a reflective layer between the support and the stimulating light absorbing layer(A), and wherein (i) a sum of a light reflectivity of a section having the reflective layer and the stimulating light absorbing layer(A) at the peak wavelength of the stimulating light is 50 to 97% of the light reflectivity of the reflective layer; and (ii) the thickness of the reflective layer is between 2 and 50 &mgr;m.
