Stable isotopes are safe, non-radioactive forms of common elements such as carbon, nitrogen and hydrogen that occur naturally in small amounts in the foods and water we consume every day. Because they ...

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; ...

Over 100 species of wild migratory birds, particularly ducks, swans, geese and various wading birds, harbour avian influenza (AI) viruses. Infections are transmitted amongst the wild birds by shedding ...

After chemical preparation and purification, very small samples from animal teeth are loaded into the magazine of an isotope ratio mass spectrometer to obtain oxygen stable isotope ratios, which yield ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...

The strongest force in the Universe is the one that holds together the protons and neutrons in an atom’s nucleus. To unlock how elements are forged, the physics of neutron stars and more, scientists ...
