摘要： A solid scintillator in an embodiment includes a polycrystal body of an oxide having a garnet structure. In the solid scintillator, a linear transmittance at a wavelength of 680 nm is 10% or more. The oxide constituting the solid scintillator has a composition represented by, for Example, General formula: (Gd 1-±-²-³ Tb ± Lu ² Ce ³ ) 3 (Al 1-x Ga x ) a O b , wherein 0

摘要： A ceramic scintillator comprises a sintered body of a lutetium oxysulfide phosphor containing at least one element selected from Pr, Tb and Eu as an activator. The sintered body of a lutetium oxysulfide phosphor contains 5 to 15 ppm of an alkali metal element and 5 to 40 ppm of phosphorus. Such a ceramic scintillator can sufficiently make use of the intrinsic characteristics of the lutetium oxysulfide phosphor and has good sensitivity in X-ray detection even when it is downsized.
