Tracer use for the protection of water resources in nuclear sites

Natural and artificial tracers can be used for nuclear sites management. Tracer techniques coupled with modelling and environmental monitoring activities are an effective tool to characterize and to foresee the radionuclide dynamic in the environment. In particular, the safeguard of water resources for human purposes must be guaranteed. In this work, the transport of tracers H-3 and I-129 in groundwater and subsoil was evaluated by means of Hydrus 1D and AMBER codes. Information on how radionuclides migrate in the environment were obtained and preliminary hypothesis on how to design the environmental monitoring network of the investigated site were deduced.
