Freebase(0.00 / 0 votes)Rate this definition: Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources. Both natural and artificial background radiation varies by location.
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.
