The reaction being considered for the production of energy using helium-3 fusion is 

   D + He-3 --> p + He-4

Note the the products are not themselves radioactive.  Also the reaction does not result in the 
production of neutrons that may activate other materials resulting in additional radioactive 
byproducts of the energy production.  This reaction does produce a fair amount of energy, which 
can be used as heat to produce electrical power if that is the end product desired.

A nice summary of and further information can be found at
