Dear Radsafe:
 
 
      From:    _jpreisig at aol.com_ (mailto:jpreisig at aol.com)    .
 
 
      Hello all:
 
              Don't want to dwell on proliferation, but  what follows. I 
think, needs to  be said.
 
           Some of the  smaller nations of the world, with nuclear weapons 
on hand, or are in the  process of
      building their first nuclear devices, seem  to need 100's or more 
centrifuges.  Hmmmm, actually, I think
      a small nation or a handful of  scientists/engineers (nowadays) could 
do some pretty severe
      U235 or Pu enrichment with 5-10 centrifuges  or less.  Probably one 
could have fewer centrifuges
      and round the clock shifts of people running  the centrifuges.  Let's 
be careful out there.
 
            On an  unrelated topic, Health Physics scientific journal 
currently has a whole issue  on Chernobyl.
      Browse it, read it, etc, even the  geologists on radsafe.
 
            Have a  good week at work....
