RE: Iodine-123



	In addition, if you use it as a radiopharmacutical, the target
material Te, is a 	contaminant.  The impurities include I-131, amoung
other radioiodine isotopes.

Nordion International of Vancouver, B.C. Canada used the following to
produce 123I:   124Xe (p,2n) 123Cs => 123Xe => 123I
I found 123mTe contaminants remained after 123I decay.
