摘要：
The present invention relates to a gamma ray detection apparatus and to a method for detecting gamma rays. The gamma ray detection apparatus includes: a secondary electron emitter which causes a Compton scattering reaction with an incident gamma ray to generate secondary electrons in the traveling direction of the gamma ray a first radiation detector facing the emission traveling direction of the secondary electrons, wherein the first radiation detector detects the positions and transfer energy of the secondary electrons a second radiation detector facing the emission traveling direction of the secondary electrons and the first radiation detector, wherein the second radiation detector detects the positions and transfer energy of the secondary electrons passing through the first radiation detector a third radiation detector facing the emission traveling direction of the secondary electrons and the second radiation detector, wherein the third radiation detector absorbs the secondary electrons passing through the second radiation detector to detect the remaining energy of the secondary electrons and a data processor including a coincidence counting circuit for determining the coincidental reaction of the secondary electrons in the first to third radiation detectors. Thus, the gamma ray detection apparatus may detect the position of a source of gamma rays by reversely tracing the secondary electrons detected in the first and second radiation detectors through the data processor.La présente invention concerne un appareil de détection de rayons gamma et un procédé de détection de rayons gamma.
