Abstract
Official abstract text for this publication.
There are provided a gamma ray detecting apparatus, including: a secondary electron emitter causing a Compton scattering reaction with an incident gamma ray to emit secondary electrons in a progress direction of the gamma ray; a first radiation detector provided to be opposed to the secondary electron emitter with respect to an emission progress direction of the secondary electrons and detecting the position and transfer energy of the secondary electron; a second radiation detector provided to be opposed to the first radiation detector with respect to the emission progress direction of the secondary electron and detecting the position and the transfer energy of the secondary electron passing through the first radiation detector; a third radiation detector provided to be opposed to the second radiation detector with respect to the emission progress direction of the secondary electron and detecting residual energy of the secondary electron by absorbing the secondary electron passing through the second radiation detector; and a data processor having a coincidence circuit judging whether the secondary electrons simultaneously react in the first to third radiation detectors, and the data processor back traces trajectories of the secondary electrons detected by the first and second radiation detectors to detect the position of a ray source of the gamma ray, and a gamma ray detecting method.
