Re: "Typical" radioisotopes in different institutions

["Frank E. Gallagher, III" <fegallag@uci.edu>]

At UC Irvine and UC Irvine Medical Center, we basically use about the same
radionuclides as Dave has listed below.  About 60% of our University
Research and Genetic Research use is P-32 (mostly nucleotides) and about
30% is S-35 (mostly amino acids and nucleotides).  I-125 use has been
declining for some years.

Because we have a PET center on campus, we use a lot of F-18 (1-2 Ci per
week) to produce a PET radiopharmaceutical for human diagnostic studies.
Note that labeling our exotic F-18 compound (NCQ115) is very inefficient,
and the half-life is very short, so most of the activity becomes waste
which decays away overnight.  We also use F-18 FDG for human studies which
we obtain already labeled, and in much smaller quantities, from the
commercial firm which operates our cyclotron and produces this specific
radiopharmaceutical for sale.
