Beta Ionization Chambers

Developed for high range beta activity monitoring, e.g. noble gas monitoring

Tag Features

  • Wide measuring range
  • Beta energy range: 70 keV to 3 MeV
  • Output signal: DC current starting at 0.1 pA
  • Saturation proof
  • Rugged construction
  • Version KB 100 PEF with integrated check volume for remote testing


The ionization chambers series KB 100 have been developed for high range beta activity monitoring, e.g. noble gas monitoring. The version KB 100 PEF has a check volume integrated in the detector housing which enables remote testing without access to the location of the detector.

Ionizing radiation produces charged particles in the gas fi lling of the ionization chamber. The transportation of these charged particles in the electrical field 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.
