Decay

Literally: breakdown. Used to describe how radioactive isotopes (radionuclides ) gradually break down to form stable isotopes. During decay smaller, particles are emitted (alpha and/or beta particles) as well as pure radiation, gamma rays. Some radioactive isotopes decay very fast (seconds to minutes) others extremely slowly (years to millennia).
