Re: Zinc-65 Intake???

["Dale E. Boyce" <dale@radpro.uchicago.edu>]

We have seen some very limited use of Zn-65 in biological research.
Over the last ten years or so we have had 5 authorized users of
Zn-65 out of a population of about 200 authorized users at any given time.
They used small amounts, .1 to 1 mCi.  It has also been used as a
gamma standard I believe.  The other place we seen it is around our
cyclotron.  It is the principle long lived isotope we see.
Cu-65(p,n)Zn-65.
