| Research Abstract |
From the analytical results of some lithofaces in the altered rocks on the high level radioactive wastes (HLW) disposal, it was showed that many natural analogue elements concentrated in many alteration zones. Natural analogue elements in the present study are lanthanoids (Ln's), uranium and thorium, especially the chemical properties of Ln's are similar to those of the radioactive materials in HLW. As conclusion in this study, it could be expected that most of the radioactive materials transferred from HLW into the strata through groundwater were uptaken and kept in the alteration zone, and the effect of delay until reaching the living environment.
