Abstract

PURPOSE: To enable measurement of a precise radiation counting rate with the aid of small size constitution whose manufacture is easy and which is strong in an environmental condition by outputting as an upper limit discriminating voltage of different voltage value is modified to equal set time to synchronize upper limit and lower limit counting.
CONSTITUTION: When a discriminating voltage set signal 29b and a control signal 29a maintained at a plurality of different specified voltage values for equal times are output from a control part 29, an upper limit counting part 27 and a lower limit part 24 are synchronized during set time to simultaneously output an upper limit counting signal 26a and a lower limit counting signal 23a indicating the number of the upper and lower limits of a voltage pulse 5 whenever the voltage value of upper limit voltage Vh from an upper limit discriminating voltage generation part 25 is instructed. Since a control and operation part 28 finds the number of the pulses 5 with the aid of the signals 23a, 26a and a data signal 28a indicating the relation of a voltage region of the minimum value or higher of the voltage Vh and pulse number are output, an energy spectrum ES figure can be obtained. Thereby a small size device whose manufacture is easy can be obtained without the influence of an environmental condition and the measurement precision of radiation counting rate can be improved.
