RECOMMENDATIONS ON SURVEYING
OBJECTS
Search of radioactivity source location
1. Disable the threshold function.
2. Switch ON the audible alarm and/or Vibration signal
functions
3. Move the device over probable location of the
radioactivity source. When doing so pay attention not
only to measurement indications but also to frequency
of signals. The signals’ frequency will increase as the
source is approached and respectively decrease as the
source is moved away from.
Performing radioactivity survey of living and
public buildings
1. Perform radiation background measurements on the
open site near the surveyed building in 5 locations.
2. Perform measurements inside the building.
3. If the registered radiation inside a building exceeds
radiation at the open site by more than 0.2 mSv/h,
this may indicate presence of unfavourable radiation
environment.
