Isotope hydrology helps governments find and understand the source of their water supplies – so they can develop management systems to reduce the risks of conflict and build resilience to drought.

It is easy to show that two elements of different atomic weight must differ either in their chemical or in their physical properties. If elements are inseparable chemically their affinity A must ...

Promethium’s short half-life and lack of stable isotopes makes it difficult to study. In addition, promethium is difficult to ...

but the rate at which heavy and light stable isotopes react during physical or chemical reactions differs. The chemical bonds and attractive forces of atoms with heavy stable isotopes are stronger ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

Properties of thorium-231, thorium-234 ... or depleted uranium. Natural isotopes of uranium are U-238, U235, and U-234 (see table above for natural abundances). Depleted uranium contains less of the ...

At the end of June 2024, the Chang'e 6 probe returned to Earth with approximately 1,935.3 grams of lunar samples.Preliminary ...

Electron shells are mentioned. Two extra neutrons are added to make an unstable isotope which explodes at the end. This clip could be used to illustrate and introduce the concept of isotopes as an ...

This created a stable compound, allowing the researchers to use X-ray absorption spectroscopy to measure the length of the ...

Isotopes trace the origin and movement of key elements and substances. Owing to isotopic fractionations associated with physical and biological reactions, nutrient and element pools within and among ...

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...
