Direction of maximum response
To detect hidden radiation sources, the alarm threshold must be
set to the lowest value that does not produce fail alarms. This is
typical a value of 0.2 to 0.3 µSv/h (20 – 30 µrem/h, µR/h).
Due to it's almost 100 times higher efficiency for gamma emit-
ters, the RadEye PRD is more suited for this task, than the
RadEye G20.
For measurements at spots with high local contamination respec-
tively dose rate, the extension adapters 42506/7075, /7076 and
/7077 in conjunction with the adapter 42506/7078 can be used.
