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

BETA IONIZATION CHAMBER WITH CHECK VOLUME

The KB 100 PEF ionization chamber has a second

electrode system within the pressurized housing.

The second system is irradiated by a built-in beta source,

which generates a continuous detector current for test

purposes.

This test current can be added to the current of the

measuring system by an external switch unit, which is

part of the NV 102 P c/f-converter.
