Saskatoon's Canadian Light Source invents new way of making isotopes

I don't really follow - if the isotopes only last a couple of days, what happens to them? It kind of sounds like they must... decay... doesn't it? Hopefully we can learn more after the news conference.

Right now isotopes are created by using radioactive material, which decays in a few hours. But the Canadian Light Source said it has invented non-nuclear based isotopes that can last a couple of days. That would allow the facility to ship isotopes to medical centres across the country.
