Abstract
A radiation position detector includes: a photodetector array constituted of unit-sized unit photodetectors; a scintillator array constituted of a plurality of tetragonal scintillator elements optically connected to the photodetector array, wherein scintillator units are each constituted of a pair of unit scintillators whose individual cross-sectional size of plane facing to right receiving surface is ¼ of the size of the unit photodetector, where at least part of which is optically connected on a surface side opposite to the right receiving surface, the scintillator units being each arranged so as to be positioned over two of the unit photodetectors; and a position evaluation unit configured to identify the scintillator unit by the presence or absence of a signal and furthermore identify one of the unit scintillators of the scintillator unit on the basis of a strength of the signal, to obtain a two-dimensional radiation detection position.
