Radio active substances Emit electrons or positrons (beta rays), Helium nuclei (alpha particles) neutrinos and anti-neutrinos and energetic electromagnetic radiation (Gamma rays).
This is from memory and the list may not be exhaustive

An individual atomic nucleus is either stable or unstable. Certain combinations of protons and neutrons are stable; all others are unstable.

An unstable nucleus has a certain half-life, which means it has 50% chance of changing to a different kind of nucleus within a certain period of time. When it changes, it may emit a proton, a neutron and/or a gamma-ray photon−−depending on what it was and what it becomes.

A radioactive substance is any substance that contains unstable atomic nuclei. Some non-radioactive substances can be made radioactive by bombarding them with protons, neutrons or gamma rays, thus converting some of the stable nuclei to unstable nuclei.
