摘要 |
A device for measuring nuclear radiation which comprises a scintillator (10) for the detection of the radiation quanta which is optically coupled to an entrance window of a photodetector (20) for converting the scintillations produced by the radiation into current pulses. The device comprises a digital circuit which is connected to a sampling and analog-to-digital conversion circuit (40) and which is used to determine the energy of each nonsuperposed radiation quantum; when the radiation quanta produce partly superposed current pulses, this circuit determines the energy content of the individual radiation quanta by extrapolations and corrections, notably by means of a memory (170 and/or 180) in which the correction coefficients are stored for performing extrapolations and corrections under the control of a sequencer (200) as initiated by a pulse edge detector (80) which detects the incidence of a radiation quantum. |
