[ RadSafe ] RE: IRF - NUREG 4884

I-125 can be accelerator produced, but the "cleanest" product is from Xe-125
production in reactors. That is why Nordion produces I-125 at Chalk River
but the accelerator produced I-123 at TRIUMF.

Actually, DOE says it may be accelerator produced
(_http://web.em.doe.gov/idb96/tab71.html_
(http://web.em.doe.gov/idb96/tab71.html) ).

And, from a press release from company called International Isotopes in
Texas:

"These major advances position the Company to initiate production and  sale
of products from the LINAC beginning early in the fourth quarter of  1998",
according to Ira Lon Morgan, Ph.D., Chairman and Treasurer of  International
Isotopes Inc.  The radioisotopes that are initially  planned for production
include I-125, Tl-201, I-123, Pd-103, Co-57, Co-60,  Ir-192, Sr-89, Y-90, I-
131, In-111, Ga-67 and F-18."

But, as I said, the issue is reasonably moot at this point, since this
material is now under the umbrella of the AEA.
