Abstract

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.
