Figure 1

Radioactivity values counted in eluates from column A experiment containing contaminated soil (Type 1). Each treatment with solution R (see text; red points), followed by 4 washings with deionised water (black point), yields the solubilization of radionuclides which pass into the eluates from the experimental column. Each peak does not correspond to a specific isotope. Radioactivity values are in DPM/ml. With the proceeding of treatments the DPM's peaks, corresponding to the major isotopes release, are retarded with respect to the first elution after addition of solution R.
