Additional Information

Product Code RH-AM 0417

Gamma Area Monitor is an air equivalent ionisation chamber based radiation monitor, which is suitable for continuous gamma rays and also for pulsed x‐ray radiation beams of linear accelerators. Ionisation chamber is a very rugged, high precision, linear, stable and reliable radiation detector. Air equivalent design makes it energy independent over a very wide energy range. It is free from dead time losses which makes it extremely durable and has long life detector. Simple associated electronics further enhances its reliability. It is designed and assembled fully indigenously, hence servicing and maintenance is quick and economical.


Range : 0-200mr/h (higher ranges are available on demand) flickering

display in case of over range. No fall back on over load.
