Activity name

RAD-MERDE: Radioanalytical Separation Method for Determining Pu, Am and Cm by alpha spectrometry - Method Expansion from Reactor water to Decommissioning and Environmental samples


NKS-B Research Area Emergency Preparedness
Project summary

Outcomes from the NKS OPTIMETHOD project (2018-2019) include an optimised method for separation of Pu, Am and Cm isotopes from NPP reactor water samples. This method is now tested in the proposed project via inter-comparison with different solid sample matrices for validating the previously optimised method for covering decommissioning and environmental samples as well, and expanding its usability. This will produce a beneficial tool for environmental and decommissioning sample analyses performed in laboratories of NPPs, national authorities, research institutes, universities, etc.


Another task is to arrange a user workshop of alpha spectrometry, inviting all interested scientists and students from Scandinavia to present their work and network with other alpha spectrometry users.
