I know *all* about half life - done them in physics class for years, and elsewhere...Pu 239 is about 24,500 years...but my original point was that any substance atomically heavier that iron (which the tokamak will need to be to stop it from being fried by the plasma) will be irradiated by the fast neutrons released. Another interesting point is that fusion reactors can breed weapons-grade Pu 239 just like our old friend the atomic pile....
