  • Scintillator plate, radiation measuring apparatus, radiation imaging apparatus, and scintillator plate manufacturing method
    Patent number: 9625586
    Abstract: [Problem] To provide a scintillator plate capable of improving the accuracy of radiation detection, and expanding the surface area for practical use while suppressing manufacturing costs, and also provide a radiation measuring apparatus, a radiation imaging apparatus, and a scintillator plate manufacturing method. [Solution] A scintillator plate (1) includes a scintillator (2) that generates scintillation light when excited by incident radiation. The scintillator plate (1) includes a scintillator layer (22) covered with scintillator powder (21) having an average particle diameter equal to or greater than the range of the radiation within the scintillator (2) when the radiation to be measured is either alpha rays, electron beams, or ion beams.
