“…The relationship is exponential and the maximum accumulation of 90 Sr is observed when the Ca concentration and electrical conductivity of the water are low.

The correlation between conductivity in water and 137 Cs in fish has also been noted (Kolehmainen et al, 1966;Sä rkkä et al, 1995).…”

“…The 134,137 Сs radionuclides were used in determinations of the time of water transfer from the Irish Sea to northern seas of Europe [1], and the 239,240 Pu radionuclides, in evaluation of the stratosphere clearance rate [2]. Global 137 Сs was used for determining the rate of sediment accumulation in deep lakes [3][4][5][6] along with 210 Pb, commonly used for these purposes [7,8].…”

Sedimentation rate in deep lakes and estiaries of the Baltic, Pechora, and Laptev Seas was determined using global 137 Сs as a sedimentogenesis marker. The sedimentation rate in Lake Ladoga and Levinson-Lessing Lake was 0.3-3 mm year -1 , and that in estuaries of the Baltic, Pechora, and Laptev Seas was 0.74-1.76, 1.0, and 3.3-5.0 mm year -1 , respectively. At a sedimentation rate of >1-2 mm year -1 , the concentration peaks of global and "Chernobyl" 137 Сs in the bulk of the bottom sediments do not overlap, and the sedimentation rate is estimated for each kind of nuclides separately. At a sedimentation rate of <1 mm year -1 , "Chernobyl" 137 Сs + 137 Сs from dumping into sea mask in the bottom sediments the subsurface maximum of the global 137 Сs concentration and prevent the sedimentation rate determination. The use of 137 Cs for sedimentation rate determinations is appropriate for the poorly studied shelf zone of Russian Arctic seas.
