Measurements of the civil exercise (ARM24c) took place at the Bürgenstock on the 29th May and on the 29th and 31st May in the area of the Beznau and Leibstadt nuclear power plants, the Zwilag interim storage facility, and the research facilities of the Paul Scherrer Institute. Atmospheric and terrestrial short-lived anthropogenic radionuclides in the western area of the Paul Scherrer Institute were detected and quantified using a newly developed Monte Carlo based full-spectrum Bayesian inversion method. A modest contribution of 16N was detected above the premises of the nuclear power plant of Leibstadt (KKL), which was resuming operations. These emissions are allowed and monitored by the competent authorities. No deviations from the natural background were detected in the vicinities of the nuclear installation of the nuclear power plant of Beznau (KKB) and the interim storage facility Zwilag. The military campaign (ARM24m) surveyed the areas of Fleurier, Sainte-Croix, Concise, Ecuvillens, Gibloux in the western part of Swizterland between September the 17th and September the 20th. Traces of the Chernobyl accident depositions were detected in the Jura heights. The international campaign (AGC24) organised by the Czech Republic was held in Prerov (CZ) from the 3rd to the the 7th of June. The exercise involved reference measurements in designated areas characterised with in-situ measurements, the search and identification of radioactive sources, the assessment of a radiologically significant region with uranium-rich soil and subsoil, and composite mapping. Such exercises provide valuable opportunities to compare and refine methodologies, practise measurements under unique conditions not present in the national territory but pertinent to emergency scenarios, and harmonise procedures and data formats. These efforts contribute to smoother and more efficient international support during radiological emergencies.
