Nuclear radiation. What do we mean by Radioactivity? Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting radiation.
Nuclear Decay (Radioactivity) Subatomic particles  Electron -negatively charged particle found outside the nucleus.  Proton – positively charged subatomic.
Types of Radiation Alpha (  ) particle is two protons and two neutrons; lowest penetrating power. Beta (  - ) particle 0 e -1 is a high-energy electron.
 Radioactivity (Radiation) is the release of high-energy particles and rays of energy from a substance as a resultof changes in the nuclei of its atoms.
What is it to be Radioactive? Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting radiation in the form of particles.
