A mixed halide scintillator having excellent scintillator properties, such as high energy resolution and high light output, is provided. A general formula AB (1-y) MyX'wX "(3-w) (where 0 ≦ y ≦ 1, 0.05 ≦ w ≦ 1, A can be an alkali metal, Can be an alkaline earth metal, X ′ and X ″ can be two different halogen atoms), and the general formula A (1-y) BMyX′wX ″ (3-w) ( Wherein 0 ≦ y ≦ 1, 0.05 ≦ w ≦ 1, A can be an alkali metal, B can be an alkaline earth metal, X ′ and X ″ are two different halogens Mixed halide scintillation material). The scintillation material of Formula (1) includes a divalent external activator M (eg, Eu2 + or Yb2 +). The scintillation material of Formula (2) includes a monovalent external activator M (eg, Tl +, Na +, and In +). [Selection diagram] Fig. 1 |
