| Abstract: | A study was made of the 239Pu, 240Pu, 238Pu and 137Cs concentrations in tidal marsh sediments of the Savannah River estuary. Tidal marshes are identified as special locations for plutonium deposition because of the high biological productivity and relative stability of sediments as compared to channel sediments. The 239,240Pu deposition averaged 3·2 mCi km−2, which is higher than land-based fallout values of about 2 mCi km−2. The 239,240Pu to 137Cs ratio was about three times higher than fallout deposition estimates, indicating a more rapid desorption of 137Cs from sediment in the saline waters of the area. |
