See full text

Provided is a scintillator having a crystal containing CsI (cesium iodide) as a host material thereof and thallium (Tl) and bismuth (Bi), and a novel scintillator which maintains a high output and simultaneously can further enhance the afterglow characteristics. There is proposed a scintillator having a crystal containing CsI (cesium iodide) as a host material thereof and Tl, Bi and O, wherein the concentration a of Bi with respect to Cs in the crystal is 0.001 atomic ppm≦a≦5 atomic ppm; and the ratio (a/b) of the concentration a of Bi with respect to Cs in the crystal to the concentration b of O with respect to I in the crystal is 0.005×10−4 to 200×10−4.
