20090309032 | GAMMA-RAY DETECTOR - A portable gamma-ray detector for indicating the intensity of a source of gamma-rays, the nature of the source, and the direction to the source relative to an axis of the detector. The detector comprises a plurality of scintillation bodies arranged around the pointing axis, for example four scintillation bodies in a two-by-two array and separated from each other by aluminium foil. Thus gamma-rays from different directions are shielded from different ones of the scintillation bodies by the other scintillation bodies. The scintillation bodies are coupled to respective photo-detectors and a processing circuit is configured to receive output signals from the photo-detectors and to provide an indication of the direction to a source relative to the pointing axis of the detector based on the relative output signals from the different photo-detectors. The processing circuit is further operable to determine the intensity of the source from the magnitudes of the output signals, and the nature of the source from a spectral analysis of the output signals. | 12-17-2009 |
