KG 151 RBT/REZ

Gamma Ionization Chamber

The KG 151 RBT/REZ ionization chambers have been

developed for low and medium range gamma dose

rate monitoring in nuclear facilities. Gamma radiation

produces charged particles (electrons and gas ions)

in the gas  lling the ionization chamber. Their dischar-

ge on the electrodes causes charge pulses. These

charge pulses are integrated to a DC current, which

can be measured in the external circuit.

The KG 151 RBT/REZ ionization chambers may be

connected to signal processing units of the RAMSYS

or TK 250 family.

APPLICATIONS

• Operational process monitoring

○ Measurement of low and medium dose rates for

process monitoring in nuclear facilities for harsh

environmental conditions
