Abstract

Distributions of ¹³⁷Cs, ^239,240Pu, Δ¹⁴C and δ¹³C measured in sediments indicated low ¹³⁷Cs and ^239,240Pu activities in the Curonian Lagoon and higher levels in the open Baltic Sea. Depleted δ¹³C_TOC values were found in the Curonian Lagoon as compared with the open Baltic Sea, while the most depleted Δ¹⁴C_TOC values were found in the Gotland Deep. The global fallout Pu dominated in the deeper zones of the Baltic Sea, while higher ²⁴⁰Pu/²³⁹Pu atom ratios were characteristic of the coastal regions.

Keywords: (137)Cs; (240)Pu/(239)Pu; Baltic Sea; Bottom sediments; Δ(14)C(TOC); δ(13)C(TOC).
