N2 - This report presents the progress on the NKS-B OptiMethod project which was conduced in 2018, aiming to establish Nordic optimal method for the determination of alpha emitters in nuclear and environmental samples. The capacity and the analytical methods used in Nordic labs for determination of alpha emitters were reviewed and summarized. 11 Nordic labs in Denmark, Finland and Sweden can determine individual alpha emitters in nuclear and/or environmental samples. Alpha spectrometry are used in most of labs for the measurement, sequential separation using different combination of ion exchange and extraction chromatography are often used for separate Pu, Am and Cm from matrices and each other. An inter-comparison analysis of a spiked water and a real reactor water was organized, 11 Nordic labs participated in this analysis and reported the analytical results of 238Pu, 239, 240Pu, 241Am, 242Cm, 243, 244Cm. The results reported by the most labs are good, and only 1-2 outlying data for each radionuclides were observed. The problems and strategies in the analysis of alpha emitters in the Nordic labs were summarized and discussed.
