The repository of low-level and long-lived radioactive waste from REE purification and treatment is presently under investigation by the French National Radioactive Waste Management Agency (Andra). This waste consists of Ra-bearing solids, mainly Ra-barite (Ba,Ra)(SO4), along with other salts such a...
