Key Points

  • The research aims to analyze historical changes in the radiation state of bottom sediments near Novaya Zemlya.
  • Analyzed radiocesium activity in bottom sediments from the 1960s and 1970s.
  • Examined the degradation of radionuclide levels over time.
  • Evaluated the self-recovery capacity of Arctic marine ecosystems.
  • Radiocesium activity in sediments has completely degraded since the 1960s-1970s.
  • The marine ecosystems showed geochemical stability and self-recovery potential.
  • No new active sources of radionuclides are necessary for this recovery.

Abstract

The article presents the results of the analysis of changes in the radiation state of bottom radiocesium activity in bottom sediments off the coast of Novaya Zemlya in the 1960s and 1970s has completely degraded. A conclusion is made about the geochemical stability of Arctic marine ecosystems and their ability to self-recovery over time, provided that there are no new active sources of anthropogenic radionuclides.
