On a very small or modest scale, from time to time there can be shortages of pharmaceutical products, for instance. We have a program called the special access program that can help us expedite unlicensed health products in these kinds of situations and speed up clinical trials of replacement products and that kind of thing. So that does exist.
Isotopes are unique in the sense that, as I said, their half-life is so short and the suppliers are so few in number that we are in this situation. Having said that, one of the take-home lessons is let's build up our relationship with alternative suppliers; let's work on various scenarios for future shortages and make sure we have at least some kind of reactive way.... We learned a lot in the days of the crisis. There was a heck of a lot of brain power in Canada being used at the ground level to try to come up with ingenious short-term triage solutions. That will help us if we face this again. I hope we don't, but if we do, we can benefit from that knowledge and experience.
