  • Wide dynamic range up to 100 kGy/h
  • Energy range: 80 keV to 3 MeV
  • Output signal: DC current starting at 1 pA
  • Operates up to 180°C (356°F) and 7 bar
  • Robust and reliable


The ionization chambers series KG 80 PED/PEF have been developed for gamma dose rate monitoring under extreme conditions. There is a check volume integrated in the detector housing which enables remote testing without access to the location of the detector.

Gamma radiation produces charged particles in the gas fi lling 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.
