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
