LA GEOCHIMICA DEL TECNEZIO
The behaviour of technetium in the geosphere is of particular importance in nuclear fuel waste management studies. In aqueous solution technetium can exist in the anionic form TcO/4-. Since clays have almost exclusive cation exchange ability, the retention of the radionuclide is hindered by the existence of a negative charge. The effect of the environmental conditions on the geochemistry of technetium released from a glass doped with 99-Tc and 95m-Tc was investigated by using a sand containing 25% of glauconite. Studies on speciation of technetium in the glass leachate were also carried out.
