KG 80 PED/PEF

Gamma Ionization Chamber

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  lling of the ionization chamber.

The transportation 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 circuit.

APPLICATIONS

• Radioprotection of workers

○ Measurement of medium and high dose rates

for harsh environment and locations with dif cult

access

• Operational process monitoring
