    • An objective is to provide a radiation flat panel detector in which degradation of a phosphor layer property during aging is inhibited, the phosphor layer is protected from chemical alteration and physical impact, and sharpness is excellent. Also disclosed is a flat panel detector possessing a light-receiving element and provided thereon, a scintillator panel possessing a scintillator sheet having a phosphor layer provided on a substrate and provided thereon, a first protective film placed on the phosphor layer side and a second protective film placed on the substrate side to seal the scintillator sheet, wherein the light-receiving element is provided on the first protective film side of the scintillator panel; and the scintillator sheet is sealed at 5-8000 Pa.
    • 目的是提供一种辐射平板检测器,其中抑制了老化期间荧光体层性质的劣化,防止了荧光体层的化学变化和物理冲击,并且清晰度优异。 还公开了一种具有光接收元件并设置在其上的平板检测器,具有闪烁体片的闪烁体面板,其具有设置在基板上的磷光体层,设置在其上的第一保护膜,位于荧光体层侧,第二保护膜 薄膜放置在基板侧以密封闪烁体片,其中光接收元件设置在闪烁体面板的第一保护膜侧上; 闪烁片在5-8000Pa下密封。
