Re: Xenon-133 monitoring

[Brent_Robinson@fpl.com]

I usually agree with you, but claiming that gas will permeate through any
dosimeter and render it useless is inaccurate.  The actual free space or gas
volume in any dosimeter is very small relative to a semi-infinite cloud.   The
effect of the gas inside the dosimeter is inconsequential in this scenario.  I
was involved in an evaluation of TLDs, electronic dosimetry and dose rate meter
response to noble gas environments in a PWR containment.  The TLD was able to
discriminate.

One more factor... Xe-133 is a gas (submersion geometry), and
therefore will permeate any dosimeter.. rendering the various filters
(TLD or film) useless in differentiating the energy or radiation type.
