摘要：In the formation waters, occurring in coal mines in the Upper Silesian Coal Basin, Poland different pollutants are present which may cause damages to the environment, among them radium isotopes. In several collieries the radium removal from mine water was necessary to mitigate negative results of radium release with mine effluents. The most efficient method of radium removal is based on the application of barium chloride, implemented in full technical scale in two of Polish collieries. Another possibility of removal radium isotopes from salty waters is an application of zeolites. In this paper, a review of different techniques is given, showing possibilities of application of different methods of radium removal, its advantages and drawbacks.
