ABSTRACT OF THE DISCLOSURE A scintillation type radiation-measuring apparatus comprising a radiation-detecting scintillator, wherein a scintillation given off from the scintillator is converted into current by a photomultiplier tube; a current amplifier generates a plurality of pulses each proportional to the intensity of said converted current; the pulses have the width clipped by a clipped pulse generating circuit; the clipped form of the pulses is delayed by a delay circuit and integrated by an integrator; the wave height value of the outputs from the integrator is sampled by a sampling circuit to provide a sampled output; and means are provided to supply instructions to start and reset the operation of the integra- tor and to commence the operation of the sampling circuit in accordance with the interval between successively detected current pulses.
