In the gas form, tritium doesn’t present an external irradiation risk for human body. But the oxide of this element might to come into – as an insidious water component – in the metabolic circuit, quickly diffusing in the whole body, representing a long – internal irradiation source, with a high biological efectivity. The special precautions for tritium are justified for all the sectors handling tritiated water especially when considering the nuclear and tritium production facilities. Therefore, the behavior of tritium in the environment is of particular interest, the knowledge of the migration of tritium, as tritiated water (HTO), in soils being of great importance.
The experimental studies of 3H migration was focused on the establishing of the physicochemical processes that influence the migration rate and on determination of the distribution coefficients, retardation factors, migration rates and times that characterize its migration in the system of beds material of the Saligny site.
