Partitioning of Cs-137 Between Sediment and Water From the Black Sea

Preliminary Caesium Data From A Cooperative Us/Ussr Monitoring Survey for Chernobyl Radioactivity in the Black Sea

“…The eight subcores were designated for analysis as follows: one for on board ship measurement of Eh and pH; one for grain size distribution and mineral composition analyses by EPA/ORP and the US Army Corps of Engineers (COE); two for Kd determinations by the US Department of Energy's (DOE) Brookhaven National Laboratory (BNL); one for heavy metals by the EPA Environmental Research Laboratory in Athens, Georgia (ERL-A); and three for radionuclides by EPA/ORP/ NAREL, WHOI, and IBSS laboratories. Preliminary results for the analyses of subcores by DOE/BNL, and by EPA/ERL-A are given in Fuhrmann et al (1991) and Neiheisel et al (1992).…”

Distribution of 137Cs and 40K in the Bottom Sediments of the Balaklava Bay (the Black Sea)

“…The concentration of 137 Cs in bottom sediments and its spatial distribution depend on the levels of its activity in water and the suspended matter content [7,15,27]. The nature of the latter can also affect the value of the radionuclide relative content on the suspended matter and, accordingly, on its flux into the bottom sediments [7,15,28]. According to the data of [5], the most polluted areas of the Balaklava Bay are its innermost part and the area near the wastewater outlet at the bay exit.…”

“…Its input into the Black Sea is due to atmospheric fallout and river runoff [6]. A number of works [6][7][8][9][10][11][12][13] are devoted to the study of the spatiotemporal variability of its content in the Black Sea region water and bottom sediments. This radionuclide is widely used to obtain the sedimentation rate quantitative estimates [12,[14][15].…”
