  • Radioecology of ⁶⁵Zn in an arm of the Columbia River Estuary

    Creator:
    Renfro, William Charles
    Abstract:
    Levels of ⁶⁵Zn in water, sediments, plants, and animals in Alder Slough, a small ecosystem in the Columbia River Estuary, were determined periodically during a one year period. Concentrations of total Zn in organisms were also measured to permit computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal fluctuations in the...

  • Vertical distribution of radioactivity in the Columbia River estuary

    Creator:
    Hanson, Peter James
    Abstract:
    In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...
