Under any scenario, the supply of radio-medical isotopes will be an issue of attention for the government and, indeed, for global partners and for the supply chain. As the committee will know, the NRU, for example, was offline for a period of 15 months about two years ago. There have been stepped-up efforts in the international community to coordinate reactor outages and reactor supply. There have also been efforts on the demand side to ensure that the available quantities of radioisotopes at any point in time are properly utilized.
The government has reinvested in sustained supply from the NRU until 2016. It is also, as you know, promoting alternative sources of supply. So there's a range of initiatives that together are intended to assure under any scenario a better security supply for medical radioisotopes.
