AB  - The activity concentrations of Pu-238,Pu-239,Pu-240 and Am-241 (for determining its mother nuclide, Pu-241) as well as activity ratios of Pu-238/Pu239+240, Pu-241/Pu239+240 and Pu239+240/Cs-137 and the mass ratio of Pu-240/Pu-239 were determined from air filter samples collected in Rovaniemi (Finnish Lapland) in 1965 to 2011. The origin of plutonium in surface air was assessed based on these data from long time series. The most important Pu sources in the surface air of Rovaniemi were atmospheri...
