A γ-radiation detection system that includes at least one semiconductor detector such as HPGe-Detector, a position-sensitive α-Detector, a TOF Controller, and a Digitizer/Integrator. The Digitizer/Integrator starts to process the energy signals of a γ-radiation sent from the HPGe-Detector instantly when the HPGe-Detector detects the γ-radiation. Subsequently, it is determined whether a coincidence exists between the α-particles and γ-radiation signal, based on a determination of the time-of-flight of neutrons obtained from the α-Detector and the HPGe-Detector. If it is determined that the time-of-flight falls within a predetermined coincidence window, the Digitizer/Integrator is allowed to continue and complete the energy signal processing. If, however, there is no coincidence, the Digitizer/Integrator is instructed to be clear and reset its operation instantly. |
