Abstract
The invention relates to a method for isolating radium from subterranean water, surface water and seepage water, in addition to drinking and mineral water, in particular from radioactive water contaminated by natural uranium and its natural disintegration products, using a reactive material consisting of several components in the form of a geopolymeric barium sulphate granulate. The radium is isolated from the contaminated water by means of the following method: said water is guided over naturally formed and/or artificially engineered cavities in the flow path of the water and/or over engineered devices, to which the water is supplied, in addition to through a homogeneous mixture of a mineral structural material with great mechanical and chemical stability and with a large internal surface area and fine-particle barium sulphate in the form of a geopolymeric barium sulphate granulate. The aim of the invention is to provide an efficient, cost-effective agent that reliably meets, guarantees or surpasses legal requirements, regulatory stipulations and water treatment standards in terms of reducing the radium activity concentration over the longest possible service life, that does not absorb additional ions or release the latter into the drinking and/or mineral water that is to be cleaned of radium and that incurs negligible costs and accumulates lower volumes for the requisite disposal and landfill.
