“…Therefore, correlation analysis was performed on the 137 Cs data and some physical and chemical properties of the dune sands (Table I), and the results are given in Table IV. At Pinery 0, the significant positive relationship between percentage CaCO 3 composition and the 137 Cs (r = 0Á66; p < 0Á05) reflects the findings of Jones et al (1984). Therefore the carbonate materials of the sands may be the main contributors to 137 Cs retention since clay and organic matter contents were very low for the materials of Pinery 0 (Table I).…”

The anthropogenic radionuclide 137 Cs has been extensively utilized as a tracer of geomorphic processes in the northern hemisphere since its deposition during atmospheric testing of nuclear devices in the 1950s and 1960s. The distribution of bomb-fallout 137 Cs was measured on a sequence of coastal dune sands and soils at Pinery Provincial Park, on the coast of Lake Huron in southern Ontario, Canada. The depth distribution within the stabilized, developed soils inland reflected the relationship between clay content and the adsorption and immobilization of the radionuclide. However, the influence of soil organic matter, silt-sized particles and vegetation cycling on the profile distribution could not be discounted. Within the geomorphically dynamic dune sands near the coast, there was a significant activity of 137 Cs even though the sands were lacking in clay-sized particles. Within a buried soil on the inland side of a large active dune blowout, the distribution of 137 Cs with depth was useful as a stratigraphic marker of the rates of accumulation of sands at that position. Therefore 137 Cs may be a useful alternative to erosion pins, sequential air photos and sediment traps in the monitoring of dune destabilization in coastal environments.

SummaryConfidence in long-term predictions of radionuclide migration from a repository engineered within a shallow sedimentary sequence depends on the quality and accuracy of the relevant computer programs that are applied in the safety assessment. Far-field research models need to incorporate the correct mechanisms and geochemical processes of mobilisation, transport and retardation. A major theme, therefore, of this three year study is to examine a number of localities where pitchb 1 en de vei ns are associ ated with sediments and to estab 1 i sh geochemical relationships of speciation and distribution of the natural decay series elements. The principal processes of interest pertaining to these elements include mobilisation and diffusion into clays, retention onto organic material, and their isotopic interactions with colloids.Data are presented for two uraniferous localities under investigation, namely Needle's Eye on the Solway Firth coast near Dalbeattie, Scotland and a disused uranium mine at South Terras in Cornwall. The results illustrate the active processes of interest and provide a tentative basis for model testing.
