Claim Text:
1. A scintillator comprising: a first scintillator layer in which first scintillation photons having a first wavelength with respect to incident radiation are generated; a second scintillator layer in which second scintillation photons having a second wavelength different from the first wavelength with respect to the incident radiation are generated, the second scintillator layer being laminated to the first scintillator layer; and a filter configured to absorb or reflect the first scintillation photons and pass the second scintillation photons through so that the second scintillation photons enter a detecting surface of a detector that detects scintillation photons, the filter being disposed between a scintillation-photon emission surface of the first scintillator layer and the detecting surface of the detector.
