(S14) adding an additive containing an ion as a luminescent center to an alkali halide powder serving as a matrix, and mechanically applying an impact force, a shear force, a shear stress, or a friction force to crush or mix the alkali halide powder and additives (S15), and the alkali halide-based scintillator powder is obtained by doping ions serving as luminescent centers in the alkali halide of the host, so that complicated control of the condition is not carried out, and a high- , An alkaline halide-based scintillator powder can be produced in the atmosphere, and a larger scintillator sheet can be produced. |
