Abstract
PURPOSE: To detect whether an output of more than specified number is generated or not from a Geiger-Muller tube and give an alarm when the likelihood of underdetecting exposure quantity occurs.
CONSTITUTION: A counter 8 which counts the detection output pulses of a GM tube 1 and a detection circuit 9 which generates detection output each time when the count value in the counter 8 reaches specified value N are provided. When the GM tube 1 goes out of order and no longer generates detection output pulses (a), an output (e) is generated from a gate 17. Thereupon, a flip-flop 18 is set by this output (e) to drive an alarm device 6, whereby the occurrence of the fault in the GM tube 1 is immediately alarmed.
