Naturally occurring crystalline phases: analogues for radioactive waste forms

摘要: Naturally occurring mineral analogues to crystalline phases that are constituents of radioactive waste forms provide a basis for comparison by which the long-term stability these may be estimated. The crystal structures and chemistry following natural presented: baddeleyite, hematite, nepheline; pollucite, scheelite;sodalite, spinel, apatite, monazite, uraninite, hollandite-priderite, perovskite, zirconolite. For each phase in geochemistry, occurrence, alteration radiation effects described. A selected bibliography is included.
