    Notes: Abstract The predictions of a sequential extraction scheme with respect to the mobility of some radionuclides (85Sr,134Cs and110mAg) in two Mediterranean sandy and sandy-loam soils, are compared to short-term soil-to-plant transfer factors and soil migration. Total soil-to-plant transfer is higher in sandy soil than in sandy-loam soil, as expected and predicted by the scheme. The relative transfer to plants of134Cs and85Sr follows the scheme predictions about exchangeable radionuclide fraction, radiosilver being less mobile than expected. Migration in soil of radiocesium and radiostrontium is also higher in sandy soil, especially for the latter radionuclide, the relative behavior of these two radionuclides being nearer to the bioavailable radionuclide fraction defined by the scheme. However, the scheme fails in predicting radiosilver migration, which is lower than deduced by the scheme.

    A sequential extraction scheme to ascertain the role of organic matter in radionuclide retention in Mediterranean soils (1993)

    Notes: Abstract A sequential extraction scheme which indicates the role of organic matter in radionuclide retention was applied to two types of Mediterranean soil (sandy-loam and sandy), with low percentages of organic matter and with different contents of clay mineral, which had been previously contaminated with a radioactive aerosol, containing85Sr,134Cs and110mAg. Different distributions were obtained for the three radionuclides, depending on the type of soil.85Sr was the most available radionuclide for both types of soil, showing significant binding to organic matter in sandy-loam soil.134Cs was the most retained radionuclide: for low-organic-matter soils, its availability seemed to depend on clay mineral content.110mAg associated with available organic sites showed a positive correlation with organic matter content.
