Cs-exchanged cuprosklodowskite

Abstract

In connection with the problem of radioactive waste disposal, investigations of uranium minerals have received a special importance. Significant attention is paid to the studies of minerals capable to incorporation of radionuclides into their structures. Burns (1999) and Burns and Li (2002) studied structures of Cs-boltwoodite and Sr-becquerelite obtained in the course of ion-exchange reactions on single crystals. Ion exchange was also investigated for several synthetic uranium compounds (Shvareva et al. 2005a, b, 2007; Ok et al. 2006).
