[ RadSafe ] GM saturation leading to failure

[Ross Beveridge]

Radsafers
 
I've encountered some training material that discourages/prohibits the use
of a GM contam instrument for radiation field detection.  The reason cited
for this is GM tube failure.  Having used this method in the field (in some
significant radiation fields) I'm not convinced this is a significant
problem, when used in an operational monitoring context.
 
Any further information/actual experience would be great.
 
Thanks in advance
