Nd isotopes and water mixing phenomena in groundwaters from palmottu (Finland)

The Palmottu uranium ore deposit, located within a granitic host rock in southern Finland, is an excellent setting for conducting analogue studies to assess radionuclide transport from the uranium deposit fractured crystalline host rock. In this context, Nd isotope ratios are used to establish the degree of water–rock interaction (WRI) and to clarify mixing processes within the groundwaters. Variations in Nd isotopes in selected water types from the Palmottu hydrosystem provide new information on the mixing history.
