Radioactive decay (Radioactivity)
Radioactive decay is the set of various processes by which unstable atomic nuclei emit subatomic particles (radiation). Decay is said to occur in the parent nucleus and produces a daughter nucleus. This is a random process, i.e. it is impossible to predict when an atomic nucleus will decay or which nuclei in a sample will.
