Abstract
In a radiation detecting apparatus, an &agr; ray and &bgr; ray are transmitted through a light shielding film but an incident light is shielded. A first light is emitted from a first scintillator by the &agr; ray transmitted through the light shielding film. The first scintillator has an emission center wavelength based on the &agr; ray. A second light is emitted in a second scintillator by the &bgr; ray transmitted through the light shielding film. The second scintillator has an emission center wavelength based on the &bgr; ray. The first and second lights are detected by two photo-detectors, respectively. The first emission center wavelength and the second emission center wavelength are different from each other.
