Radiation

Radiation

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. This includes: • electromagnetic radiation consisting of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation • particle radiation consisting of particles of non-zero rest energy, such as alpha radiation, beta radiation, proton radiation and neutron radiation • acoustic radiation, such as ultrasound, sound, and seismic waves, all dependent on a physical transmission medium • gravitational radiation, in the form of gravitational waves, ripples in spacetime__###newline###__ Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts, which is enough to ionize atoms and molecules and break chemical bonds.
