Background radiation. The natural radiation that is always present in the environment. It includes cosmic radiation which comes from the sun and stars, terrestrial radiation which comes from the Earth, and internal radiation which exists in all living things. The typical average individual exposure in the United States from natural background sources is about 300 millirems per year.
Radiation is the process where waves or energy particles (e.g.: Gamma rays, x-rays, photons) travel through a medium or space. The unstable nuclei of radioactive elements are trying to become stable by emitting radiation. Radiation can be either ionizing or non-ionizing. Ionizing radiation has high energy, and when it collides with another atom, it will be ionized, emitting another particle (e.g. an electron) or photons.
