Abstract: ► We determined ²⁴⁰Pu/²³⁹Pu mass ratio from environmental samples in Finland. ► The samples were peats, lichens, air filters, grass and hot particles. ► Samples were analyzed with extraction chromatography followed by ICP-MS. ► ²⁴⁰Pu/²³⁹Pu ratio agreed with previously determined ²³⁸Pu/^239+240Pu activity ratio. ► The samples were contaminated by global fallout and/or the Chernobyl accident.
