Thank you very much, Mr. Chair, and thank you very much for being with us today.
I'm particularly concerned about the medical isotopes, so I'm going to focus my questions on that area. You all know that about 20,000-plus patients undergo nuclear imaging procedures every week in our country. As we learned here not all that long ago, the system can be at times, and quite often is, rather fragile, so I want to talk a little about the supply of radioactive isotopes.
The pending shutdown of medical isotopes at Chalk River means that about 40% of the world's supply is going to vanish, if I understand that correctly. That shutdown is scheduled to happen in 2016. We know from budget 2015 that the government announced plans to postpone the shutdown of NRU until 2018, but are those two related? Are we still shutting down the production of isotopes in 2016, even though there's been an extension to 2018 for NRU?
