title = "Formation of (Ba,Ra)SO4 Solid solutions – Results from barite (re)precipitation and coprecipitation experiments",
abstract = "Retention of 226Ra2+ by barite in aqueous solution is studied in a barite (re)precipitation experiment with 226Ra2+ doped barite suspensions at I = 0.1 mol·(kg H2O)–1 at ambient temperature. After about two years a steady state is achieved, demonstrating that 226Ra2+(aq) concentration is controlled by the solubility of a (Ba,Ra)SO4 solid solution and several orders of magnitude below the Ra2+ solubility with respect to a pure RaSO4(s) endmember. Results of the barite (re)precipitation experiment are compared to recent (Ba,Ra)SO4 coprecipitation experiments by Rosenberg and co-workers at ionic strength I = 0.7 – 7.0 mol·(kg H2O)−1.",
