Transition to a new level of research and development in the fields of radiation solid state physics, applied radiochemistry and materials science, with a prospect of to nanotechnology applications. The main emphasis will be on the modification of the materials at the nanometer scale and on the study of the effects produced by heavy ions in matter with the aim of revealing the fundamental mechanisms and of the development of nanotechnology applications for ion beams. Modernization of the FLNR facilities for the production of medical isotopes and developement of materials modification methods.
