Abstract
For compensating for the rate dependent change of charge-to-voltage conversion factor in a drift-type radiation detector there is detected a change in a momentary photon hit rate affecting said drift-type radiation detector. A drain current flowing through an integrated amplifier of said drift-type radiation detector is changed by an amount proportional to the detected change in said momentary photon hit rate.
