The purpose of this study was to identify the chemical elements which, through the neutron activation mechanism, would contribute the most to the overall radioactivity and to the overall ingestion toxic potential for the public. The chemical impurities, also at very low concentrations, have been ascertained to give, in many cases, a considerable contribution to the radwastes environmental impact, as in the case of SiC/SiC fibre composites materials or low-activation martensitic steels. The origins of the impurities have been identified and ways to use this information in the material production processes for nuclear fusion application are suggested.
