によりその微少電流信号レベルに応じたレートでパルス
信号に変換し、このパルス信号の計数値と設定値とを比
較演算し、計数値が設定値以上のとき、その旨の信号を
出力することを特徴とする放射線監視装置。The minute current signal input from the radiation sensor is converted into a pulse signal by an integrating amplifier at a rate corresponding to the minute current signal level, and the counted value of this pulse signal and the set value are compared and calculated, and the counted value is determined as the set value. A radiation monitoring device characterized in that in the above cases, a signal to that effect is output.
