Friends,

In India Co-60 is regularly produced in some of the pressurized heavy water reactors.

you have to keep in mind, that not many reactors have the capabilities
needed to irradiate samples and remove, and process them. Power
 reactors
have no interest in isotope production. The same is true at federal
facilities. The feds got out of the business years ago as private
 companies
began to distribute. I doubt seriously if any of the federal facilities
would produce radionuclides at the costs that AECL charges.

We have the same problem with Am-241. The feds did a separation of
 material
20 years ago. They ran out of separated Am-241 a couple of years ago.
 Since
that time, we purchase Am241 from Russia.

The same with tritium foils. The only U.S. manufacture ceased
 production a
few years back. There is no one that I'm aware of producing Tritium
 foils
any longer.

In many of these areas, new technology is beginning to replace nuclear
techniques. This is driven by costs as well as the security issues that
 are
currently being forced on the nuclear community.

Peter

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?
