Radiation injuries are caused by ionizing radiation emitted by such sources as the sun, x-ray and other diagnostic machines, tanning beds, and radioactive elements RADIATION SOURCES Natural sources Radon gas 55% Inside body 11% Rocks, soil, and groundwater 8% Cosmic rays 8% Artificial sources Medical x rays 11% Nuclear medicine 4% Consumer products 3% Miscellaneous (including occupational exposure, nuclear fallout, and the production of nuclear materials for energy and weaponry) < 1% released in nuclear power plant accidents and detonation of nuclear weapons during war and as terrorist acts. Ionizing radiation is made up of unstable atoms that contain an excess amount of energy.
