In the radiation detector, the peak wavelength of light emitted by the scintillator is 360 nm or less, and the peak wavelength of light after conversion by the optical conversion layer is 400 nm or more. Preferably, the refractive indexes of the scintillator and the optical wavelength conversion layer are both 1.35 to 1.65.
