Check with MDS Nordion of Canada.  They make Co-60 sources for irradiation
and other uses.

Does anyone on the list have any information, or references to publications

that can provide information on the manufacture of Cobalt-60 sources.  In  
particular whether Cobalt enriched steel is used and if so what other  
radionuclides may be produced at the same time e.g. Fe-55 or Ni-63.
