摘要: PROBLEM TO BE SOLVED: To provide a radiation monitor device that greatly shorten test time, and changes items according to circumstances by automatically sequentially optimizing the frequency of pulse.SOLUTION: A measurement unit 12 in which detection pulse is input measure counting rate (n) comprises: amplifier 11 amplify pulse; height discriminator 122 outputs digital when voltage amplified within predetermined range; counter 123 inputs an addition 123a feedback subtraction 123b, integrated value M obtained integrating difference between both; synthesis circuit 124 generate integration control 125 performs weighting counts; computing element 126 find (n); changeover switch 128 over 121; 129 123.
