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 integrator and to commence the operation of the sampling circuit in accordance with the interval between successively detected current pulses.
