Geohydrologic considerations in the management of radioactive waste
George D. DeBuchananne
1974, Nuclear Technology (24) 356-361
Nongaseous radioactive wastes occur as liquids containing high-level concentrations of radionuclides, liquids containing low concentrations of radionuclides, and solids contaminated by radioactivity. Whether released by accident or design into the earth or onto the earth’s surface, only water is capable of transporting significant quantities of radionuclides away from burial sites....
Regional flow system and ground-water quality in western Ohio
Stanley E. Norris
1974, Journal of Research of the U.S. Geological Survey (2) 527-531
Most relatively deep wells drilled in the carbonate aquifers in western Ohio tap a recognizable regional flow system encompassing all or parts of several major basins. The principal recharge area includes the higher, central part of the region, where much of the terrane is hummocky to hilly glacial moraine. The...
A mineral separation procedure using hot Clerici solution
Sam Rosenblum
1974, Journal of Research of the U.S. Geological Survey (2) 479-481
Careful boiling of Clerici solution in a Pyrex test tube in an oil bath is used to float minerals with densities up to 5.0 in order to obtain purified concentrates of monazite (density 5.1) for analysis. The "sink" and "float" fractions are trapped in solidified Clerici salts on rapid chilling,...
