TIM: Oh, and by the way, radioactivity isn't just something humans created; it occurs naturally, too. An animation shows a bird flying over trees and a mountain range. TIM: Just about everything on the planet, from rocks to plants to animals, contains traces of radioactive elements. (microwave oven beeping) TIM: Oh, the hotdogs are defrosted!.

An atom is made up of three main particles; the proton, the neutron and the electron. Hydrogen-1, an isotope of hydrogen, has no neutrons, just the one proton and one electron. A positive hydrogen ion has no electrons, just one proton. All other atoms have at least one proton, one neutron, and one electron each. Radiation, in general, exists throughout nature, such as in light and sound. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. [1] [2] This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays.
