description A portable light weight hand held dosimeter for measuring both dose rate and total dose received. Dose rate is sensed then amplified by a logarithmic electrometer, the signal is processed through a differential amplifier and provides a reading on a calibrated voltmeter. Total dose is sensed and generates a voltage to charge a capacitor, which activates a field effect transistor network, the output is amplified in a compound transistor amplifier which drives a mechanical register.
