Circuit for stabilizing the amplification of scintillation probe output pulses

The invention is aimed at improving the measuring sensitivity and stability of scintillation probes in connection with the use of radioisotopes in industrial facilities. Stabilization can be achieved with the aid of on-off control using a counter with forward-backward transmission output, a flip-flop and a function generator by which the amplification is adjusted, so that changes at the scintillator and at the electron multiplier are corrected
