Nitric acid leaching of representative uranium ores and mill tailings from the western U.S. mining districts removes up to 98% of the /sup 226/Ra and /sup 230/Th, yielding a residue containing 17 to 60 pCi of radium per gram. At best, this is an order of magnitude greater than that in surrounding soils, but about the same level as a standard proposed for building materials in the United Kingdom. Data are also presented on the water penetration and leaching of tailings, the solubility of BaSO/sub 4/, and radon emanation coefficients of ores, tailings, and nitric acid-leached residues.
