Abstract
The present invention provides a scintillation counter that includes a measuring chamber accommodated to take the sample and viewed by two photodetectors, preferably photomultipliers, that can be operated in coincidence. Associated with the chamber is an additional scintillator, preferably an inorganic crystal scintillator, optically isolated from the chamber by a light-permeable wall and mounted so that the scintillation light generated in the additional scintillator is guided predominantly only to one of the two photodetectors. A comparator is used for registering pulse amplitude disparity between the photodetectors to distinguish low-disparity, sample generated pulses and high-disparity, additional scintillator generated pulses.
