Abstract:
1. A radiation detector comprising: a scintillator, wherein scintillator crystals for converting radiation into the fluorescence are arranged in the crosswise and lengthwise directions of the scintillator, and wherein a first, second, third and fourth layer are arranged in the height direction of the scintillator; and a plurality of reflecting plates that extend in the crosswise direction or the lengthwise direction, for reflecting the fluorescence, in the gaps between mutually adjacent scintillator crystals, wherein: reflecting plates that extend in the crosswise direction are arranged in the lengthwise direction with spacing equal to the size of one scintillator crystal so as to alternate between the first layer and the second layer of the scintillator, reflecting plates that extend in the lengthwise direction are arranged spanning the first layer and the second layer of the scintillator and with spacing equal to the size of two scintillator crystals in the crosswise direction, and the reflecting plates that extend in the crosswise direction and the reflecting plates that extend in the lengthwise direction are fitted together to structure a reflecting plate lattice that has the same height as two layers of the scintillator.
