Definition of Radiation
• “Radiation is an energy in the form of electro-magnetic waves or particulate matter, traveling in the air.”

Radioactivity
• If a nucleus is unstable for any reason, it will emit and absorb particles. There are many types of radiation and they are all pertinent to everyday life and health as well as nuclear physical applications.
Ionization
• Ionizing radiation is produced by unstable atoms. Unstable atoms differ from stable atoms because they have an excess of energy or mass or both.
