Abstract
Det beskrives en fremgangsmåte for å lette fjerning av radionuklider, som f.eks. uran og thorium, og/eller en eller flere av deres radionuklide detre fra titanholdig materiale som omfatter å bringe det titanholdige materialet i kon- takt med ett eller flere reagenser ved en forhøyet temperatur som velges for å for- bedre tilgjengeligheten for minst en av de radionuklide døtrene i det titanholdige materialet, idet reagensene velges for å danne en fase ved den forhøyede tempera- turen som dispergeres på overflatene av det titanholdige materialet og oppfanger radionuklidene og nevnte en eller flere radionuklide døtre.A method is described for facilitating the removal of radionuclides, e.g. uranium and thorium, and / or one or more of their radionuclide deters from titanium-containing material comprising contacting the titanium-containing material with one or more reagents at an elevated temperature selected to improve the availability of at least one of the the radionuclide daughters in the titanium-containing material, the reagents being selected to form a phase at the elevated temperature dispersed on the surfaces of the titanium-containing material and intercepting the radionuclides and said one or more radionuclide daughters.
