The moly-98-plus neutrons process is done already in the world. There's a lot of that made, but the generators are not of the quality that we use in North America. That's the purification scheme. I think the time scale for that is similar. For the moly-100, the removing of a neutron, I think that's on a similar time scale also. The technology for that is a little more in hand, but there are always things that take time.
Everything I mentioned is for the medium term. The other area I'd like to mention is that there will have to be a new generation of cyclotrons, I think, for PET imaging. I see smaller compact cyclotrons being designed and put in, say, every hospital in Canada, along with PET scanners on a five- to ten-year basis. That's yet another direction to go.
