[en] Summary
The electrochemical reduction of uranium and neptunium ions is achieved in aprotic solvents in presence of acrylonitrile. The cathodic deposit on a usual metal consists of a grafted poly- acrylonitrile layer in which actinide oxide or actinide metal has been inserted as a consequence of the overall cathodic reaction. As polyacrylonitrile is an insulating material, the electrochemi- cal polymerization reaction is stopped when the polymer layer thickness reaches 1000 A at maximum. The material we thus produced may be used as an alpha
spectroscopy source and we report here the results originating from the preparation of more than hundred samples.
