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.
FEATURES
● Wide measuring range up to 100 Gy/h
● Saturation proof
● Robust construction
● Long life time
● Energy range: 80 keV to 3 MeV
● Output signal: DC current starting at 0.1 pA
● Ambient temperature up to 180°C (356°F)
APPLICATIONS
• Operational process monitoring
○ Measurement of low and medium dose rates for
process monitoring in nuclear facilities for harsh
environmental conditions
