Distribution of radionuclides in the Columbia River streambed from the nuclear reactors, Hanford Reservation to Longview, Washington
Technical Report
·
OSTI ID:4309030
Until all the eight reactors that were cooled by once-through flow of treated Columbia River water were shut down in 1971, their cooling-water effluents were the main source of dissolved and panticulate radionuclides in the Columbia River. The distribution and quantities of radionuclides accumulated in the riverbed were investigated; reconnaissance surveys of radionuclide concentrations and particle size of surficial sediment and sediment at depth were made; radionuclide discharges at two locations were defined; and radionuclide concentrations in surficial sediment at three river locations were observed semimonthly. Data presented on radioisotopes in Columbia River sediments include: seasonal variations; fixation in coarse and fine sediments; stratigraphic distribution; geographic distribution, and total accumulated quantities of /sup 60/Co, /sup 51/Cr, /sup 54/Mn, /sup 46/Sc, and /sup 65/Zn.
