(2) Utility Model Registration Scope of the Claims In the noise prevention circuit according to claim 1, the variable pulse width circuit is set to a zero state when an output pulse from a radiation detector is input, and a reset signal is input. The variable width control means includes a clock pulse generation circuit and a control circuit that specifies the number of clock pulses to be counted. , While the flip-flop is in the set state, a clock pulse is input from the clock pulse generation circuit, and when the clock pulse is counted up to the number specified by the control circuit, the clock pulse is sent to the variable pulse width circuit. and a timer circuit that sends out an output as a reset signal, and the control circuit determines the designated number of clock pulses to be counted for the timer circuit depending on the number of output pulses from the flip-flop in a unit time. A noise prevention circuit for a radiation measuring instrument, characterized in that:
