Short summary
We measured concentrations and isotope ratios of plutonium in air filters collected in Finnish Lapland in 1965–2011. Radioactive-contamination sources were global nuclear-testing fallout and the Fukushima and SNAP-9A accidents. Both real and hypothetical nuclear accidents were studied with atmospheric-dispersion modeling. The radioactive-contamination effect on Finnish Lapland would be minor from an intended nuclear power plant and negligible from a floating nuclear reactor in the Barents Sea.
