Ionization Chambers

An ionization chamber is a detector that makes use of the ionization effect of X-rays or gamma-rays on an internal gas.
Ionization chambers are suitable for use in high radiation environments.


Long life and high stability

Chemical cleaning and high-temperature exhausting under vacuum condition on the detector completely eliminates impurities.
Strict management of the filler gas.

Improved shock resistance
