Measurements and modeling of airborne plutonium in Subarctic Finland between 1965 and 2011
The activity concentrations of 238,239,240Pu and 241Am (for determining its mother nuclide, 241Pu) as well as activity ratios of 238Pu/239+240Pu, 241Pu/239+240Pu and 239+240Pu/137Cs and the mass ratio of 240Pu∕239Pu were determined from air filter samples collected in Rovaniemi (Finnish Lapland) in...
