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.
