It's my recollection as well. So in 2007, when Chalk River went down the first time, the other four reactors around the world were operating and supplying isotopes. What confuses me is that when Chalk River went down in 2007, I can recall the minister and several ministers in the House of Commons saying we need to reopen it, fire Linda Keen, because this is a life and death situation for Canadians.
Advance forward to 2009 and we have four out of four other reactors shut down. Chalk River goes down and the minister strikes a committee to report back to Canadians in the fall, a committee to which she hasn't named anyone yet, and part of their mandate is to assess dangers of delayed action and reaction.
The confusion I have, and I think many Canadians have, in terms of the concern over the surgeries they need and in terms of the diagnoses they need, is that an alternative has been suggested today, again, repeated also in the House, that thallium might make up the shortage.
Ms. Ballantyne, could you tell us what percentage of all the treatments we currently and in the past have used these other isotopes for that can thallium replace?
