Oak Ridge National Laboratory is boosting isotope production to secure the US supply chain after Russian shortages.

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...

An isotope is one of two or more atoms of the same chemical element with the same atomic number, occupying the same position on the periodic table and having almost identical chemical behavior, but ...

Lead (Pb) isotopes provide valuable insights into the origin of Pb within a sample, typically allowing for reliable fingerprinting of their source. This is useful for a variety of applications, from ...

In the rapidly evolving landscape of nuclear medicine, the integration of diagnostics and therapeutics - known as theranostics - represents a groundbreaking shift in how we approach the treatment of ...

Sixty years ago, the very first samples of rainwater were collected for the Global Network of Isotopes in Precipitation (GNIP), while the science of isotope hydrology was still taking its first steps.

Water isotopes serve as tracers of hydrological processes and as proxies for past climates archived in ice cores. The isotopic signal is acquired throughout the hydrological cycle—through evaporation ...
