Description

As part of an investigation concerning the fate of 226Ra during uranium ore milling and long-term tailings storage, the growth of potential host solids-barium sulfate and lead sulfate has been investigated- on mica, a model surface. The kinetics of dissolution of barium sulfate - and of a barium sulfate solid containing 228Ra as a trace component into 10-3M sulfuric acid were subsequently investigated using a flow-cell and radiotracer techniques. It was found that their dissolution of both the barium sulfate host and the 228Ra trace component was congruent. The dissolution reaction appears to be surface controlled. (author) 14 refs.; 6 figs
