ABSTRACT:
There are provided a scintillator (130) comprising a structure in which a plurality of scintillator layers (131, 132, 135) having columnar crystal structures are stacked with, and a radiation detection device using the scintillator. There are also provided a scintillator (130) comprising a structure in which a plurality of scintillator layers (131, 132, 135) and light-transmitting intermediate layers (138, 139) disposed among the plurality of scintillator layers (131, 132, 135) are alternately stacked with, and a radiation detection device using the scintillator. Accordingly, it is possible to control the scintillator layer in such a manner as to reduce irregularities on the surface of the scintillator layer, and reduce an abnormal growth portion such as a splash existing inside the scintillator layer. Therefore, a radiation detection device can be obtained which has high reliability, high resolution, and small correction error of a digital image.
