Preparation of high specific activity radiochemical forms of Vanadium, Manganese and Thallium for metallo-toxicological studies.

Production methods of "high specific activity" of the radionuclides of Vanadium, Manganese and Thallium are presented.Both cyclotron (JRC-Ispra) and nuclear reactor (Triga MarkII, University of Pavia) have been used. Selective radiochemical separations developed for the radiotracers preparation in the "non carrrier added form" are presented and discussed.
