Abstract
According to the embodiment, a radiation detector includes a photoelectric conversion substrate converting light to an electrical signal and a scintillator layer being in contact with the photoelectric conversion substrate and converting externally incident radiation to light. The scintillator layer is made of a phosphor containing Tl as an activator in CsI, which is a halide. A concentration of the activator in the phosphor is 1.6 mass %±0.4 mass %, and a concentration distribution of the activator in an in-plane direction and a film thickness direction is within ±15%.
