Have teams use their charts to find their isotope's half-life. A half-life is a measure of the average lifetime of a radioactive substance, and specifies the time it takes for one-half of the ...

Certain isotopes are unstable and undergo a process of radioactive decay, slowly and steadily transforming, molecule by molecule, into a different isotope. This rate of decay is constant for a ...

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 ...

Users must go through radiation safety training and the project approval process before they can begin ordering and using radioactivity. In addition, EHS must approve all isotope orders. The approval ...

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 ...
