| heal.abstract | The interaction of gamma -rays with smectites induces paramagnetic defects in the structure of these clay minerals. The EPR spectra of three different smectites detect the creation of structural defects and trapping of organic free radicals in the clay structure upon irradiation. The defects are assigned to positive holes or trapped electrons stabilised by existing local charge imbalances in the mineral lattice. The organic radicals are derived from organic compounds present as impurities in the crystal lattice of the clay minerals. In addition, gamma -rays cause migration of small interlayer cations (such as Li+) into the layers, as clearly evidenced by EPR and FT-IR reflectance spectroscopies. | en |
