Also, many thorium ores as well as thorium, which is obtained as a by-product of uranium mining, contain traces of Th, a radionuclide in the decay chain of U. Neutron absorption in Th also results in the formation of... [Pg.378]

Phytoremediation methods for radionuclide decontamination do not involve hyper-aeeumulators, except possibly for uranium. Plants require a long period of eontact with a contaminant to evolve the ability to hyper-aeeumulate, and most uranium ores are located underground and so are not in eontaet with plants. Soils with high concentrations of uranium are present only where uranium is or has been mined or processed, but these have only been in existenee for a few deeades. [Pg.141]

Waste that contains long-lived, naturally occurring radionuclides Contains uranium, thorium, or radium, e.g., from mining and milling of ores or decommissioning of nuclear facilities 1 No radiological restrictions or systems similar to those for short-lived waste6... [Pg.206]

Nuphar lutea, a plant very sensitive to perturbations such as those which may accompany the mining of metal ores, was also examined in order to measure the content of radionuclides in a series of uranium group elements (11). In experiments carried out in the Okanagan region of south-central British Columbia, N. lutea was found to accumulate natural uranium and 226 Ra, and the amounts of these elements were found to depend on the season and also on the pH of the mud. Nuphar lutea was also used in investigations into the concentration of137Cs and potassium in Lake Ulkesjon in the southern part of Sweden (12). [Pg.217]

Many coastal ecosystems have elevated levels of metals and radionuclides (14). Anthropogenic sources of stable isotopes of metals include sewage disposal plants, electroplating plants, and mining and dredging operations sources of radioactive isotopes include effluents from nuclear power plants and submarines, medical establishments, and uranium ore mining. The pollution from most of these operations results from routine or accidental discharges and are either continuous or episodic. [Pg.611]

By mining of ores and minerals, appreciable amounts of natural radionuclides, in particular " K, Th, and the members of the thorium, uranium and... [Pg.395]
