“…It is also being absorbed by vegetation through root uptake and is being recycled to the soil surface through litterfall, where it probably again adsorbs to the <50 mm fraction and possibly organic matter as the litter is gradually decomposed. The above findings support the results of other studies on radiocaesium distribution in forested soils of North America (Ritchie and McHenry, 1990;McCabe et al, 1991). In the active dune areas of Pinery, human-induced destabilization of sands has caused problems in retaining the natural dune system (Bowles, 1980).…”

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.

“…However, less is known regarding the effects of organic matter on 137 Cs distribution in soils and sediments (Livens and Loveland, 1988;McCabe et al, 1991;Tomlin et al, 1992). Ritchie and McHenry (1990) summarized research on the use of fallout 137 Cs as a marker in establishing sediment accumulation rates.…”

“…3). McCabe et al (1991) found that 40 K increased with depth from the soil surface to 15 cm in Ah horizons of soils from the Lake Erie basin in Ontario. They concluded that this was a function of the leaching of 40 K weathered from minerals.…”

“…The Huron Fringe (Dunes) samples included those from a study of soil genesis on a dune chronosequence (VandenBygaart and Protz 1995a, b). The Norfolk Sand Plain and Haldimand Clay Plain profiles were initially sampled for a study of the influence of soil fauna on the distribution of radionuclides (McCabe et al 1991).…”

In Canada and the United States approximately 82% of the annual total dose of radiation to any person comes from terrestrial and cosmogenic sources. The soil is also the main source of radon exposure to humans. Therefore it is important to know the background levels of natural and anthropogenic radioactivity in soils. In this study the radionuclides 40K, 226Ra, 232Th and 137Cs were measured in the soils of southwestern Ontario in order to determine the background levels and to understand the soil profile distribution. Clay content is the most important variable affecting the background levels of 40K, 226Ra, and 232Th in the soil. The profile distribution of these radionuclides is further influenced by pedogenic processes, particularly carbonate leaching from the solum and clay illuviation from the Ae to the Bt horizons. The lateral and vertical distribution of bomb-fallout 137Cs is influenced by soil management such as tillage, biopedoturbation by soil animals such as earthworms and groundhogs, soil erosion and soil organic matter cycling. Multiple regression analysis showed that clay content, sand content, percent CaCO3, pH and organic carbon content had variable influences on each of the radionuclide contents in the soil.
