Abstract

The major part of the extractable uranium is associated with a readily acid-soluble fraction in both ore and tailings. The major part of the extractable 226Ra was associated with an iron, manganese hydrous-oxide fraction in the ore and tailings. Thorium-230 was the least leachable of the radionuclides studied. The major portion of the extractable 230Th was associated with alkaline-earth sulphate precipitates, organic matter, or both. The specific effects of milling on each of the nuclides are discussed.-Author

The aqueous geochemistry of uranium in a drainage containing uraniferous organic-rich sediments, Lake Tahoe area, Nevada, USA

Anomalously uraniferous waters occur in a small (4.2 km2) drainage in the west-central Carson Range, Nevada, on the eastern side of Lake Tahoe. The waters transport uranium from local U-rich soils and bedrock to organic-rich valley-fill sediments where it is concentrated, but weakly bound. The dissolved U and the U that is potentially available from coexisting sediments pose a threat to the quality of drinking water that is taken from the drainage. The U concentration in samples of 6 stream, 11 spring and 7 near-surface waters ranged from <1 to 177 ??g l-1 with an average value of 17 ?? 14 ??g l-1 for stream and spring waters. This value significantly exceeds a reported regional average value of ~5 ??g l-1, and is comparable to proposed maximum contaminant levels of U in drinking water. Calculations that utilize chemical compositions of the waters and thermodynamic data indicate that uranyl-carbonate and uranyl-phosphate complexes are the major inorganic species of dissolved U. In addition, dialysis experiments suggest an association of at least some dissolved U with macromolecular organic matter, particularly in near-surface waters that are in contact with organic-rich sediments. Calculations of the saturation index for uranous and uranyl-bearing minerals indicate that all of the waters are undersaturated with uranium minerals as long as ambient Eh is oxidizing (i.e. > 0.1 V). Possible precipitation of U(IV) minerals is predicted under the more reducing conditions that are particularly likely in near-surface waters, but the inhibitory effects of sluggish kinetics or organic complexing are not considered. These combined results suggest that a process such as adsorption or ion exchange, rather than mineral saturation, is the most probable mechanism for uranium fixation in the sediments. -Authors

Use of track detectors for the evaluation of emanating radium content of soil samples.

The emanating Ra contents of background and contaminated soils were measured using commercial alpha-track detectors sealed with samples in glass Mason jars for a 179-day period. The observed track densities were linearly correlated with independently measured emanating Ra contents using gamma assays for total Ra and Rn emanation measurements. The simple new jar test exhibits high sensitivity and requires minimal equipment and user's training. It has applications in indoor Rn and building material studies as well as geochemical exploration.-Authors

A review of applications of U-Th-Pb isotope systematics to investigations of uranium source rocks.

U, Th and Pb concentrations and the isotopic composition of Pb can be used to evaluate crystalline rocks as a source for U in sedimentary deposits. Under favourable geologic circumstances, the technique can yield information on both the timing and the amount of U released to the sedimentary environment. The technique is best suited to the study of Archean rocks that have high U/Pb, a known common Pb composition, and a simple two-stage history. Less ideal rock units can also be evaluated, but conclusions reached for rocks of Phanerozoic age or younger will generally be qualitative at best.-Author
