A change in supply to meet isotope demand

A change in supply to meet isotope demand: http://seekingalpha.com/article/976731-a-change-in-supply-to-meet-isotope-demand "Nordion does not produce isotopes itself, but uses the NRU reactor in Canada, which is scheduled to be shut down in the next four years. The reactor is currently operating at full capacity, yet the demand is greater due to a shortage in other regions. The company has had to evolve over the years with more efficient means of producing medical isotopes-- in other words, getting more bang for the buck. Nordion has become the world leader in cobalt-60, which is used to produce gamma radiation, and also in the creation of targeted therapies with yttrium-90. Therefore, Nordion is a diversified company; but if the NRU reactor were to close, it would be a huge hit to the company. The company does have a backup isotope supply in Russia; but in terms of supplying the U.S. (its largest market), the costs would drastically rise if the NRU reactor closes because of the logistics involved in transporting and producing various isotopes."
