N1 - Funding Information:
The authors would like to thank the Nordic Nuclear Research NKS-B programme ( www.nks.org ) for funding the DTM Decom III project in which the intercomparison exercise was carried out. The authors would also like to thank the other participating laboratories, namely Technical University of Denmark, Norwegian University of Life Sciences, Fortum Power and Heat Oy, Institute for Energy Technology Kjeller and Taiwan Power Company Radiation Laboratory for provision of data and collaboration. National fundings were given by Finnish Research Programme on Nuclear Waste Management KYT 2022. A-LABOS-EX-PR-SC-01 project is thanked for the CEA self-funding. CEA LASE laboratory operators Gabriel Lambrot, Margaux Giuliani, Christèle Colin, Elodie Laporte, Jacques Bubendorff and René Brennetot are thanked for their experimental contributions.

N2 - A need for method validation in radiochemical analyses of decommissioning waste is a challenging task due to lack of commercial reference materials. Participation in an intercomparison exercise is one way for a laboratory to assess their performance and validate their analysis results. A three-year project within the Nordic Nuclear Safety Research (NKS) community was initiated in order to carry out intercomparison exercises on difficult to measure (DTM) radionuclides in real decommissioning waste. Both Nordic and Non-Nordic laboratories participated. This paper reports the results from the final year of the project focusing on beta- and gamma emitter (i.e., easy to measure, ETM) analysis in spent ion exchange resin. The assigned values were derived from the participants’ results according to ISO 13528 standard and the performances were assessed using z scores. The results showed generally good performances for both DTMs and ETMs.
