摘要： A radiation detector includes a first scintillator, a second scintillator, a first photoelectric conversion layer, and a second photoelectric conversion layer. The first scintillator converts β rays into first scintillation light. The second scintillator converts the β rays into second scintillation light. The first photoelectric conversion layer is provided between the first scintillator and the second scintillator and converts the first scintillation light into electric charges. The second photoelectric conversion layer is provided between the first photoelectric conversion layer and the second scintillator and converts the second scintillation light into electric charges. The first scintillator, the second scintillator, the first photoelectric conversion layer, and the second photoelectric conversion layer are each formed with an organic material as a main component. The thickness of the second scintillator is larger than the thickness of the first scintillator.
