ABSTRACT:
The invention provides an alpha-beta-gamma scintillation spectrometer of the type having a scintillation crystal with two photomultiplier tubes coupled thereto comprising an inhibition circuit which inhibits pulses from passing to a multichannel analyzer of the spectrometer for a period of about 1 to about 20 msec following the detection of a slow pulse, whereby delayed light emission background impulses originating from the crystal and not from a sample are not counted and only pulses in coincidence are registered and stored thereafter.
