PROBLEM TO BE SOLVED: To provide a transparent scintillator material for quickly converting an excited radiation, e.g. X-rays, into scintillation light. SOLUTION: This scintillator material contains a cubic garnet host and praseodymium as the activator. Such a scintillator material can be a polycrystalline ceramic material. This ceramic material is prepared by sintering a powder formed by precipitation. Such a scintillator material can be incorporated into a computer tomography(CT) apparatus 100 or other x-ray photographic apparatuses, and also into high-speed-responsivity X-ray detectors.
