> Fusion has no toxic or radioactive bioproducts.

D-T fusion, which is the easiest to achieve and perhaps sustain, directly produces He nuclei (that is, alpha particles) and rather energetic neutrons at 14 MeV. Those neutrons, aside from being a form of ionizing radiation themselves, are bound to transmute some of the surrounding material into radioactive isotopes. So, I don't think that "no toxic or radioactive byproducts" is correct. However, the results are easier to handle than those of fission reactors.

I don't know a lot about fusion, however «no radioactive bioproducts» seems to be off. I just read Wikipedia, and the deuterium-tritium reaction produces neutrons. Radiation seems to be not as bad as for fission reactions, however it is NOT radiation-free.
