Abstract

PURPOSE: To make unnecessary the prediction from a radioactive ray generator by switching two switches through a control circuit in accordance with the detected quantity of the ray so that the outputs of the ray meter are consecutively stored in a memory corresponding to each switch.
CONSTITUTION: The ionized current pulses from an ionizing box detector 1 are integrated by a charge integrating type potentiometer 2 and fed to switches S1 and S2. On the other hand, the switches S1 and S2 are alternately switched through a control circuit 8 and a pulse detecting circuit 7, which is operative to detect the existence of the ionized current pulses of the detected quantity of the ray from the detector 1 by differentiating the output of the potentiometer 2, so that the detected ionized current pulse values before and after the pulse generation of the radioactive ray are alternately stored in memory circuits 4 and 6. Thus, without predicting the radiation ray tenerating pulses, the pulse-shaped radioactive ray can be metered through an airthmetic circuit 9 and a display circuit 10.
