DTM-DECOM II: Intercomparision exercise in analysis of DTM in decommissioning waste 




NKS-B Research Area Measurement strategy, technology and quality assurance  



The lack of reference materials in DTM analysis in decommissioning waste is an on-going issue. The EU-Insider ( project on decommissioning having an objective on reference materials will produce a concrete reference material, but at least according to the discussions in the mid term meeting, the focus will be on gamma emitting radionuclides and stable isotopes. Therefore, DTM-Decom II has a relevance in the competence building / validation of radioanalytical methods in the participating laboratories. DTM-Decom II will carry out an intercomparison exercise on activated concrete since concrete and steel are the most abundant decommissioning materials to be analysed. The DTMs of interest in activated concrete are H-3, C-14, Cl-36, Ca-41, Fe-55 and Ni-63. The final list of DTMs to be analysed in DTM-Decom II will be selected in the kick-off meeting.
