Recently I ran into a web page entitled "Energy of the Future." It makes the point that fission has radioactive byproducts but that there are some actual fusion processes that produce little or no radioactive products.
The two fusion processes talked about are Deuterium-Tritium and Hydrogen-Boron. The first produces little radioactivity but the second doesn't produce any at all.
In order to produce the Tritium necessary for Deuterium-Tritium fusion it must be created in the reactor with neutrons since it is not found in nature. And it is radioactive. The end of this fusion process is a Helium atom and a high energy neutron which can make other matter radioactive. But for the Boron-Hydrogen fusion process; from begining to end; there are no radioactive atoms. The end product for it is only Helium. But when enough helium atoms are created an occasional boron atom will fuse with a helium instead of a hydrogen atom and produce a low energy neutron. This neutron is not as dangerous as the high energy neutron produced in the Deuterium-Tritium process.
I believe these fusion processes that produce little or no radioactivity will be our energy future. How long will it take for us to get there? I don't know.
Unfortunately I cannot create a link to the original web page since it doesn't exist anymore. Google though has cached it.
You can Google: "Energy of the Future" focusfusion.org.
Then click the <cached> option on the link with the title: Energy of the Future. It might not be the first link that turns up under this search so don't be dismayed.
