     Roger,

     Give  us more specifics on your request.  At various  times,
and for various reasons/experiments, I've used activated charcoal
to  trap  Xenon-133  -> I've used charcoal filters  in  personnel
respiratory  protection  with excellent results - as  an  exhaust
(vacuum) trap during uptake studies on monkeys and as a filtering
method  for ambient (breathing space) monitoring (same series  of
experiments).   In the case of the vacuum trap, aquarium charcoal
(a  cheap  source) in a large bag absorbed/adsorbed the xenon  so
well  that  we were able to use the "in house" vacuum system  and
not have to worry about contaminating the whole system.

Does anybody know of a method to trap Xe-133. Since it is a noble
gas, I
suspect it would be difficult. I have seen a reference to the use
of activated
charcoal  for a Xe trap but it was not very informative. Any help
would be
appreciated.
Thanks,
