A circuit is described for discriminating between types of particles detected by scintillation counters based on different decay times of the scintillations. In the circuit, one form of that claimed in British Patent 823,263, two pulses are derived from a photomultiplier tube, the pulse amplitudes being proportional to the area and amplitude of the scintillation pulse, respectively, and a difference pulse in turn is derived from these pulses and applied to a pulse amplitude discriminator. The electrodes for producing the pulses are the anode and a dynode, and the deriving means are such that the pulses are of opposite polarity. A connection including a resistor is made between each deriving means and a common output resistor across which the difference pulse is developed. (D.L.C.)
