    Research outputpeer-review


    Convective migration experiments are carried out by percolating porewater through clay cores labelled with the relevant waste radioelements. Migration parameters of the clay are determined by monitoring the radioactivity in the effluent and by post experiment examination of the longitudinal activity profile in the cores. The spatial distribution of the tracers is examined by microscopic methods on thin sections prepared from the same core material. Results are reported for the migration behaviour of uranium in Boom clay. The presence of naturally occurring uranium in clay is studied by the fission track method while the alpha-track technique is used for the distribution of U-233 in a migration experiment.
