Gamma Ionization Chambers
The KG 50/51 SEC ionization chambers have been
developed for high range gamma dose rate monito-
ring under accident and post accident conditions.
Gamma radiation produces charged particles in the
gas fi lling of the ionization chamber.
The transportation of these charged particles in the
electrical fi 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.
The KG 50/51 SEC ionization chambers may be
connected to signal processing units, both, of the
RAMSYS or TK 250 family.
APPLICATIONS
• Radioprotection of workers
○ Measurement of medium and high dose rates
for harsh environment and locations with diffi cult
access
