3.3 Locating a Radiation Source
When seeking a radiation source during observation of the surroundings, use the FLIR
identiFINDER R200 in "Finder Mode" to determine the exact location of the source.
1. Move the instrument to a low-radiation position for a background measurement.
2. Wait until the FLIR identiFINDER R200
finishes the background measurement.
If conditions are such that there is
no time for a background check, exit the background measurement (not
recommended) by pushing the right button on the thumbpad which initiates
the right-most command in
the taskbar
when in "Finder Background" mode. The instrument will
then use the most recent
background taken after it was switched o
3. Move the instrument around the area under observation to find the radiation
source.
The count rate in the "Finder"
mode offers continuous meas-
urement and will trend up as
the FLIR identiFINDER R200 is
moved closer to a source, and
the counts fall off as the dis-
tance becomes greater.
Source strength will also be a
factor.
