摘要： An apparatus for detecting neutron radiation includes a first section with a high neutron absorption capability and a second section with a low neutron absorption capability. The second section includes a gamma ray scintillator having an inorganic material with an attenuation length of less than 10 cm for gamma rays of 5 MeV energy. The material of the first section releases the energy deployed in the first section by neutron capture mainly via gamma radiation. A substantial portion of the first section is covered by the second section. An evaluation device determines the amount of light detected by a light detector for one scintillation event, and the amount is in a known relation to the energy deployed by gamma radiation in the second section. The evaluation device classifies detected radiation as neutrons when the measured total gamma energy Esum is above 2,614 MeV.

摘要： A detector for the measurement of radiation, preferably ionizing radiation, includes a medium, means for the conversion of the radiation energy absorbed by the medium into electrical charge, means for digital sampling of the charge signals, means for the determination of a calibration factor K, and means for the stabilization of the output signals of the detector. The medium at least partly absorbs the radiation to be measured. The electric charge is at least partially proportional to the energy of the radiation. The sampling is done preferably with a sampling rate between 1 and 1000 MHz. Further signal processing is digital. The calibration factor K has a fixed relation with respect to the decay time τ of the medium. The output signals of the detector are mainly proportional to the radiation energy, and are stabilized with the help of the calibration factor K.
