Biogeochemical aspects of uranium mineralization, mining, milling, and remediation
Natural uranium (U) occurs as a mixture of three radioactive isotopes: U, U, and U. Only U is fissionable and makes up about 0.7% of natural U, while U is overwhelmingly the most abundant at greater than 99% of the total mass of U. Prior to the 1940s, U was predominantly used as a coloring agent, and U-bearing ores were mined mainly for their radium (Ra) and/or vanadium (V) content; the bulk of...
متن کاملEnvironmental health risk from past uranium mining and milling activities
In the last few years several European countries undertook closure and environmental remediation of old uranium mining sites. This is the case for Portugal. Due to concerns about public health, environmental radioactivity was recently investigated in a number of counties in the Centre-North of Portugal where the extraction and chemical treatment of uranium ore was carried out, as well as in ref...
متن کاملRadiation protection of workers from uranium mines and of the public living nearby uranium mining and milling facilities
As part of the program of nuclear power development, the Russia Federation plans to increase uranium production and to improve supply from existing uranium mining and milling facilities. Moreover, development of new uranium ore deposits is also envisaged. A corollary of these developments is the placing of a high priority on environmental and human health protection Special attention should be ...
متن کاملThe geochemistry of natural wetlands in former uranium milling sites (Eastern Germany) and its implications for uranium retention
Discharge from former uranium mining and milling areas is world wide a source of elevated uranium contents in wetlands. The efficiency of organic rich wetland environments for entrapment and accumulation of uranium was assessed in this work using hydrogeochemical field studies of natural small-sized wetlands in Thuringia and Saxony, Eastern Germany. The objective was to estimate, if artificial ...
متن کاملPopulation monitoring: experience with residents exposed to uranium mining/milling waste.
More emphasis should be placed upon using biomarkers to address potential health risk among populations exposed to high concentrations of environmental toxicants. Among these studies, those which integrate exposure measurements with analyses of validated biomarkers may provide more reliable information for risk assessment and disease prevention. We have used a multidisciplinary approach to eluc...
