Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope.

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

Kyle Clavier, left, and Dan Clayton are helping develop a standardized screening method to determine the most important radioactive isotopes to monitor from all of those produced by an advanced ...
