RADIATION MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To simply monitor a dose over a wide range continuously by applying Campbell measurement to radiation dose measurement. SOLUTION: A pulse from a CdTe sensor 16 serving as a radiation sensor is integrated by a charge amplifier (CA) 17 and converted into a pulse with a pulse amplitude according to a quantity of an electric charge. An MSV measurement device 18 inputs the pulse and carries out n-th power averaging arithmetic to convert it into an MSV measurement value. A current measurement device 19 measures an average current value, and a pulse measurement device 20 measures the number of pulses. An energy evaluation device 21 evaluates average radioactive energy from these measurement values. A dose evaluation device 22 evaluates a dose equivalent from the evaluation.
