Abstract:
1. A radiation image detector comprising: a scintillator panel comprising a radiation transmitting substrate having thereon a phosphor layer having a columnar crystal structure of CsI produced with a vapor deposition method; a protection cover provided at a side of the radiation transmitting substrate opposite the phosphor layer, provided that incident radiation enters through the protection cover; and a flat light-receiving element provided at a side of the radiation transmitting substrate opposite the protection cover, the flat light-receiving element comprising a plurality of light-receiving pixels arranged in a two-dimensional form and capable of converting light emitted from the scintillator panel to electricity, the flat light-receiving element being arranged to allow pressure contact with the scintillator panel; wherein the radiation image detector satisfies the following Formula (1): wherein S(cm the phosphor layer has a thickness of 400 to 1,000 μm, and the area of the radiation transmitting substrate is 500 to 5,000 cm the radiation transmitting substrate has a thickness of 50-500 μm and is made of a flexible resin film selected from the group consisting of a polyimide film, a cellulose acetate film, a polyester film, a polyethylene terephthalate film, a polyethylene naphthalate film, a polyamide film, a triacetate film, and a polycarbonate film.
