Smith, G D

An integrating dosimeter is designed comprising a radiation detector, e.g., an ionization chamber, a capacitor, an electrometer valve, a trigger circuit, and an electromechanical register. In operation, the ionization current charges the capacitor, leading to a voltage propontional to the integrated dose; as soon as this voltage equals the bias voltage of the trigger circuit, the register reading is advanced by one digit and the capacitor is discharged. In this way, it is not necessary to know beforehand the magnitude of the dose to be measured. Circuit diagrams are presented for one embodiment of this invention and for a suitable trigger circuit.
