- How Radiation Works - HowStuffWorks
Radiation is the emission and transmission of energy in the form of electromagnetic waves or particles Radiation can be ionizing or nonionizing radiation, and only ionizing radiation has enough energy to potentially cause damage to cells and DNA
- Radiation Basics | NRC. gov
Radiation is energy given off by matter in the form of rays or high-speed particles All matter is composed of atoms Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom's outer shell contains other particles called electrons
