Radiation detecting apparatus

摘要

In a radiation detecting apparatus (11), an alpha ray and a beta ray are transmitted through a light shielding film (12) but an incident light is shielded. A first light is emitted from a first scintillator (14) by the alpha ray transmitted through the light shielding film (12). The first scintillator (14) has an emission center wavelength based on the alpha ray. A second light is emitted in a second scintillator (15) by the beta ray transmitted through the light shielding film (12). The second scintillator (15) has an emission center wavelength based on the beta ray. The first and second lights are detected by two photo-detectors (17), respectively. The first emission center wavelength and the second emission center wavelength are different from each other.
