An international collaboration of scientists working with the FAIR Phase 0 program at the GSI Helmholtzzentrum für ...

while each atom of the Pu-239 isotope contains 145 of these neutral particles. Radioactive isotopes are further characterized by their half-life, the time it takes for any given amount of the element ...

Researchers have discovered an "unexpected" accumulation of the radioactive isotope beryllium-10, deep underneath the surface of the Pacific Ocean. The team hopes their discovery could serve as an ...

Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant stable isotope(s) of an element have ...

The table below shows the fraction by weight of the three isotopes in any quantity of natural uranium, their half lives, and specific activity. The half life of a radioactive isotope is the time taken ...

A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant. Half-life describes ...

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 ...
