Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how ...

Uranium-series isotopes, particularly the ratios of uranium isotopes such as 234U and 238U, are valuable tools in studying sediment transport, weathering processes, and the geochemical evolution ...

In nature, uranium isotopes are typically found in radioactive equilibrium ... In experiments, very young animals have been found to absorb more uranium into their blood than adult animals when they ...

and the time it takes for one-half of a particular isotope to decay is its radioactive half-life. For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million ...

The D-A model predicts the distributions (profiles) of uranium and U-series isotopes across a bone section. It has been shown how these distributions reflect the uranium uptake history of a bone, with ...

Combining two techniques, analytical chemists at the Department of Energy's Oak Ridge National Laboratory have become the ...

ASP Isotopes defended its proprietary Aerodynamic Separation Process and highlighted its recent advancements, including the development of enriched Ytterbium-176 and plans for uranium enrichment ...
