[ RadSafe ] GM failure through saturation

[neildm at id.doe.gov]

It's not failure through saturation, it's failure through poking a hole
in the membrane window of the pancake GM tube.

Amazingly easy.

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
 
Ross
