KG Series

Gamma Ionization Chambers

Gamma radiation produces charged particles in the gas filling of an ionization chamber. Transportation of these particles in the electrical field between the electrodes generates a DC current, which can be measured in the external circuit.

Tag Features

• Large measuring range

• Saturation proof

• Energy range: 60 or 80 keV to 3 MeV

• Output signal: DC current starting at 0.1 pA

• Long life time

• Versions KG … P with check volume for remote testing

• Version KG 50 SEC for post accident conditions


The sensitivity of an ionization chamber is proportional to the gas quantity inside, and therefore to the specific mass of the gas and to the volume of the detector. But, the sensitivity is independent of temperature and environmental pressure.
