Abstract (en)

The most significant sources of anthropogenic radioactivity in the Baltic Sea are the global fallout after the nuclear weapon tests and the Chernobyl NPP accident in 1986. A large number of nuclear tests resulted in the globally distribution of plutonium isotopes (239Pu – 6.52 PBq, 240Pu – 5.35 PBq, 241Pu – 142 PBq) worldwide while during the Chernobyl NPP disaster 6.1 PBq of Pu isotopes were introduced into environment. Satellite accident (SNAP-9A) over the South Pacific in 1964 released ~ 0.6 PBq of 238Pu into the atmosphere. The amount of Pu isotopes introduced into the Baltic Sea after the nuclear weapon tests was estimated at about 16- 19 TBq (HELCOM 1995) whereas the total Pu derived from the Chernobyl NPP releases was found to be as less than 10% (Holm, 1995).
