[ RadSafe ] Isotope shortage affects patients

Mo99 is made by placing HEU (highly enriched uranium) into a reactor where
it undergoes fission. According to what I've read 6% of the HEU that breaks
down becomes Mo99. Only a few countries have the technology to make HEU.
Canada imports their HEU from the US. Iran supposedly wants to make HEU to
make Mo99. GWB doesn't think that is what they plan to do with it. Trade in
HEU is very regulated.

I agree that it has nothing to do with the Canadian health system and very
little to do with AECL. The problem is with the isotope production
companies. Why is there only one reactor that produces Mo-99?
