This is almost a repeat of my answer to the previous question. A lot of medical isotopes have to be short-lived, because you can't inject something into someone's body that's going to be there for a long time, so they decay quickly. Things like molybdenum-99 and cobalt-60 are used widely internationally, but they remain fairly radioactive even after their use for, say, killing cancer cells has ended, because they decay over time. Again, you need a strategy to manage those when they're returned to Kanata and Nordion or wherever.
