RADIATION MONITOR FOR X AND GAMMA RAYS
BARC Radiation Monitor (RADMON) is a G. M. based,
battery powered, handheld monitor featuring simultaneous measurements of
exposure (upto 2 mSv) and exposure rates (upto 200 mSv/hr). A built-in
audio alarm during exposure measurements alerts the user to hazardous
condition. The integral exposure alarm level can be preset anywhere upto 2
mSv. The detector is provided with an energy compensating filter so as to
achieve an overall response within 20% in the energy range of 60 keV to
1.25 MeV.
