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

Amazingly easy.

Subject: [ RadSafe ] GM failure through saturation

I've encountered some training material that discourages/prohibits the
of a GM contam instrument for radiation field detection.  The reason
for this is GM tube failure.  Having used this method in the field (in
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
