RADIATION DETECTION APPARATUS AND METHOD FOR IDENTIFYING POSITION OF EXTINCTION OF IN-COMING RADIATION

摘要

PROBLEM TO BE SOLVED: To provide a radiation detection apparatus and a method for identifying the position of extinction of in-coming radiation, capable of enhancing the accuracy of position detection of the in-coming radiation by a simple technique.;SOLUTION: The radiation detection apparatus 50 includes: a scintillator array 10 composed by two-dimensionally arranging a plurality of kinds of scintillators 21-24 which generate rays of fluorescence having mutually-different waveforms by interaction with radiation (in-coming radiation γ); a photodetector 30 for detecting fluorescence generated in a scintillator 21-24, and a determination part for determining the kind i of the scintillator 21-24 where the interaction occurs, based on information on waveforms Di of fluorescence detected by the photodetector 30. From the position of the detection of the fluorescence by the photodetector 30 and the kind i of the scintillator determined by the determination part, a scintillator hit by the in-coming radiation γ is identified.;COPYRIGHT: (C)2010,JPO&INPIT
