GIM 202K
Wide Range Gamma Area Monitor
The GIM 202K forms part of the RAMSYS product
line. It has been developed to monitor dose rate in
nuclear facilities under mild operating or post-
accident conditions.
The very simple concept of its ionization chamber
allows this monitor to have a great reliability of prime
importance in the safety related applications, in a
mild environment.
