Importance of redox interface regarding the fate and behaviour of radium in surface water impacted by NORM

Abstract : Usual approach to remove radium from industrial wastewater consists in the co-precipitation of radium with barium. Although barite is being known as a highly insoluble phase, it is also suspected to be dissolved under sulphate-reducing conditions. Our study focused on the interactions occurring at the water-sediment interface of a former settling pond operated by the coal mining industry of the Upper Silesia Coal Basin (USCB), Silesia, Poland. Based on sediment composition and pore water analysis our results provided new insight for studying the fate and behaviour of radium in a NORM storage reservoir evolving towards a natural ecosystem.
