Nuclear techniques applying energetic ion beams to study structural defects, surfaces and near surface changes in non-stoichiometric ceramics are described. Most examples are for uranium oxide and nitride and for titanates. New results on leaching of UO(2), formation of U(3)O(7), leaching of SYNROC and radiation damage effects due to ion implantation of UO(2) and UN are treated. The techniques described in detail are Rutherford backscattering, RBS (with and without channelling), nuclear reactions such as 23Na(p,alpha)20Ne, elastic recoil deflection analysis, ERDA and high resolution alpha-spectroscopy. Elements between H and actinides and gradients in their concentration near surfaces can easily and accurately be measured.
