Description
Summary:Sediment cores collected from Lake Khanka (Xingkaihu) and Amur Bay were analyzed for concentrations of .sup.137Cs and .sup.210Pb, along with the detailed mineralogical and elemental composition. The depth distribution and specific activities of .sup.137Cs in the sediment cores indicated that the investigated area is not contaminated. Maximum activity of .sup.137Cs is 10 Bq/kg, and its inventory is 0.16 Bq/m.sup.2. Despite some variation in mineralogical profiles, the sedimentation process was uniform over the investigated period. The sedimentation rate in the eastern part of Lake Khanka (Xingkaihu) was estimated to be 1.6 mm/year, and 0.43-0.5 mm/year in Amur Bay.
