Isotopes of plutonium (Pu), cesium (Cs), and cobalt (Co) introduced into the Hudson River Estuary from fallout deposition, the erosion of fallout-contaminated surface soils, and nuclear reactor effluent (isotopes of Cs and Co only) have been measured in water column samples collected from 1975 to 1980 Isotopic measurements conducted independently by two research groups utilizing different sampling and analytical techniques have been summarized. The major conclusions drawn from the work are that for water samples collected by the two laboratories over similar time periods, the mean concentrations of nonfilterablePu (<0.45 μm) were identical at 0.13 fCi/l, mean concentrations of bothCs andPu in suspended particulates were more divergent at 2,270±920 pCi/kg (±1 SD) and 1,430±430 pCi/kg forCs, and 19±8 pCi/kg and 12±4 pCi/kg forPu The behavior ofPu andCs within the water column is shown to diverge within brackish waters Specifically, the magnitude of theCs distribution coefficient ( K ) can be expressed as an inverse power function of the chloride ion concentrations for chlorinities between 0.1 and 4 g Cl/l No difference in thePu K has been observed between fresh and brackish waters Based on the expected inventories ofPu andCs within watershed soils, the current downstream transport of these radionuclides represents fractional mobilization rates on the order of 1-4 (×10) per year [ABSTRACT FROM AUTHOR]
