Chalk Formations as Natural Barriers towards Radionuclide Migration

    Research output: Contribution to journalJournal articleResearch


    A series of chalk samples from the cretaceous formation overlying the Erslev salt dome have been studied in order to establish permeabilities, porosities, dispersion-, diffusion-, and sorption characteristics of the chalk. The chalk was found to be porous (∊≈0.4), however, of rather low permeability (k≈10-7 cm/sec). It was found that the material exhibits a retarding effect on migration of cationic species as Cs+, Sr2+ , Co2+, and Eu3+, whereas ionic species as Cl- move with the water front. The geochemical implications are discussed
