Popis: | The combined use of artificial (137Cs, 238,239+240,241Pu, 241Am) and naturally occurring (210Pb/226Ra, 40K) radionuclides as tracers for dating of the Black Sea sediments has allowed to reveal the recent increase in radioactive contamination of this basin with 137Cs after the Chernobyl accident. This is presumably caused by the prolonged input of the man-made radionuclides that showed a rise in the late 1990s – early 2000s, and by a possible post-deposition remobilization of 137Cs from the seabed. |
