"A couple additions to Dave's excellent list:

Hospital:	Gd-153 (in Quadramet, a replacement for Sr-89 palliative
bone therapy)
		F-18 (a "long-half-life" positron emitter, as FDG)
Rad Therapy:Pd-103 (prostate implants, seeds)

Thanks for doing most of the work, Dave!"

Actually, the Gd-153 is used in sealed line sources for bone density 
scanners.  

Quadramet (R) uses Sm-153 to treat pain from cancer that has 
metastasized to the bone.

Also, Y-90 is being used in a number of clinical trials for cancer 
treatment.

In the nuclear medicine field, the Mo-99 is never used in patients.  It is 
incorporated into a technetium generator that supplies Tc-99m for a 
variety of nuclear med scans.  Mo/Tc is probably the largest single 
radionuclide (activity-wise and probably in terms of the number of
procedures) in nuc med.
