摘要：

Percolation tests (i.e. routine laboratory migration experiments) have been performed to evaluate the diffusion behaviour of a number of long-lived radionuclides in Boom Clay, a candidate geological host formation for high level radioactive waste (HLW) in Belgium. Among the many potentially hazardous radionuclides under investigation are Se-79, Zr-93, Np-237, Am-241 and Am-243. Actinide migration experiments have been carried out with Np-237 and Am-241, while for the studies with Se and Zr the radioisotopes Se-75 and Zr-95 were used. Their transport patterns in the Boom Clay were examined using a combination of a NaI(TI) detector and High-Purity Ge detectors either on the dissolved matrix (Np-237, Am-241) or directly on the clay (Se-75, Zr-95).
