Abstract
According to an embodiment, a scintillator includes a scintillator layer and a radiation absorption layer. Scintillation photons corresponding to incident radiation are generated in the scintillator layer. The radiation absorption layer is laminated to the scintillator layer. The radiation absorption layer faces a detecting surface of a detector that detects the scintillation photons.
Claims2
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.
