Beta Ionization Chambers

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 hou-

sing which enables remote testing without access to

the location of the detector.

Ionizing radiation produces charged particles in the

gas  lling of the ionization chamber. The transporta-

tion of these charged particles in the electrical  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 cir-

cuit.

APPLICATIONS

• Ef uent release monitoring

○ High range beta activity monitoring, e.g. noble gas

monitoring
