Radimage Gamma Area Monitor (Ion Chamber Based)
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.

Radimage Last Man Out Switch
RH-LM0817
Advised by AERB “Last Man Out Switch” (LMOS) is designed for radiation safety. Soon after patient setup, the technician needs to press the LMOS after ensuring that nobody is present in the treatment room. This activates an audio‐visual alarm for 30 seconds and during this 
period the operator needs to close the  door and switch “ON”  the beam. Works on latest micro controller based technology. Simple to install and  easy to use.
