Description

The KG 50/51 SEC ionization chambers have been developed for high range gamma dose rate monitoring under accident and post accident conditions. Gamma radiation produces charged particles in the gas filling of the ionization chamber. The transportation of these charged particles in the electrical fi eld and their discharge on the electrodes causes charge pulses. The charge pulses are integrated to a DC current, which can be measured in the external circuit.

The KG 50/51 SEC ionization chambers may be connected to signal processing units, both, of the RAMSYS or proTK family.
