Description

The KG 220 SEF ionization chamber has been developed for low and medium range gamma dose rate monitoring in nuclear facilities. There are two versions with optimized energy response for measuring dose rates in Sievert or Gray units. Gamma radiation produces charged particles (electrons and gas ions) in the gas filling of the ionization chamber. Their discharge on the electrodes causes charge pulses. These charge pulses are integrated to a DC current, which can be measured in the external circuit.

The KG 220 ionization chambers may be connected to signal processing units of the RAMSYS or proTK family.
