and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

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 ...

Collagen was extracted and analyzed for bulk stable isotopes of carbon-13 (δ 13 C) and nitrogen-15 (δ 15 N) and compound-specific isotopes of individual amino acids. Radiocarbon dating provided ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...
