GM probes and RF / EMF

[jgbarnes@ix.netcom.com (JAMES BARNES)]

I'm continuing to follow the thread regarding RF interference with GM tubes:

So now I have some questions:

If I have a standard gas filled detector with several hundred volts applied to 
it, wouldn't it start to behave like an antenna at some point if I stuck it into 
an RF or EMF field?

Another way of stating it, I guess, would be; Can't the detector itself 
intrinsically act as an RF antenna even if the rest of the electronic circuitry 
is fully shielded?

Or, another way; Wouldn't the application of high voltage make the induction of 
stray fields across the anode and cathode much easier (i.e., create an 
amplification effect through a different phenonema than normally seen in cascade 
discharge)?

I guess from what I had run into in the past, I'm not completely comfortable with 
the notion that the probe is insensitive to the RF / EMF and has nothing to do 
with the response ("it's all in the electonics").

Someone please enlighten me at bit.
