Thermodynamic Considerations Underlying the Migration of Radionuclides in Geomedia: Oklo and Other Examples
The prediction of migration or retention of radionuclides in geomedia is one of the major problems associated with radioactive waste disposal. Use of...

Interaction of Waste Radionuclides with Geomedia: Program Approach and Progress
Radioactive wastes require isolation from the biosphere for thousands of years. One option for isolation of these wastes is disposal in deep geologic...

Hydrothermal Reactivity of Simulated Nuclear Waste Forms and Water-Catalysed Waste-Rock Interactions
A key consideration in the long term safe disposal of nuclear wastes is their stability in the repository environment. If the assemblage of waste...

Pollution through Trace Elements
There is an enormous literature on the chemistry, geochemistry, geology, toxicology, and epidemiology of the so-called “trace elements.” Of the...

Resources
Although it is not yet clear what population the earth is capable of supporting, or what the limiting prerequisite of life will be, these two...

The impact of paleomagnetism on paleoclimatic studies
Paleomagnetism presents the paleo-bioclimatologist for the first time with an independent determination of latitude. In combination with...

Dynamics of Pesticide Residues in the Environment
Residues of pesticides or their degradation products have been reported in a wide variety of environmental samples. The concentrations of compounds...
