What is nuclear decay?

Back

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation of the nucleus into a different element or isotope.

What is fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy and often harmful radioactive waste.

What is fusion?

Back

Fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing a significant amount of energy, and is the process that powers stars.
