Abstract
In the scope of the studies carried out on the geological disposal of radioactive wastes, it is essential to assess the migration behaviour of long lived radionuclides as a function of the
physicochemical conditions (pH, redox potential, temperature, pressure, ...), the nature of the host rocks and the chemical composition of the underground waters. In this study, we have
considered the case of selenium which is an element of importance because of its long lived under its 79Se isotope.
Key words: Selenium / radioactive wastes / biogeochemical processes.
