Abstract
To the problem of measurement error becomes larger by superimposing the leakage current to the current signal of the radiation detector, the electric charge integration unit which outputs the sawtooth pulses by the discharge of the detected to charge the radiation is connected to a time of discharging the charge and is a constant current circuit is disconnected during the charge accumulation is provided, between the constant current circuit and the charge integrator, the leakage current of the switching circuit is connected a first backflow cutoff circuit suppresses during charge accumulation, the leakage current compensation circuit connected to an input of the storage unit of charge leakage of the said the first backflow cutoff circuit second backflow cutoff circuit having a second backflow shutoff circuit of one of the backflow cutoff equivalent characteristics current has to be offset in the opposite direction.
