We have the capability at the Mcmaster Nuclear Reactor to irradiate such 
samples in the hot cell using our cobalt source.  We need some 
information on the dose rate and total gamma dose required. The 1 Kg mass 
is not a problem.  We can also set up irradiation sites in the pool if 
uniform dose over a large volume is an issue.
