Radiation is a process in which a body emits energy that propagates through a medium, or through empty space, to be absorbed by other bodies. Radiation may also refer to: Physics * Electromagnetic radiation, radiation that takes the form of a self-propagating wave of electric and magnetic fields, including such phenomena as radio waves and visible light * Ionizing radiation, radiation that is of high enough energy to cause atoms to lose or gain electrons, rendering molecules, such as proteins, incapable of functioning * Nuclear radiation, radiation, especially ionizing radiation, that emanates from nuclear processes such as radioactive decay * Thermal radiation, electromagnetic radiation that emanates from every object above absolute zero, in proportion to the fourth power of the temperature of the object * Synchrotron radiation, also called a synchrotron light source, electromagnetic radiation generated by the acceleration of fast moving charged particles through magnetic fields Medicine * Radiation therapy, also called radiotherapy, a medical treatment that involves exposing part or all of the body to a controlled amount of ionizing radiation * Radiation poisoning, a form of damage to organ tissue due to excessive exposure to ionizing radiation * Radiation, characteristics of an affliction, such as pain, to spread to other parts of the body than the origin Evolutionary biology * Evolutionary radiation, a diversification into several lineages from a common ancestor * Adaptive radiation, an evolutionary radiation to fill many ecological niches Regulatory law * Intentional radiator, radio waves that are produced by an electronic device as a necessary part of its function, such as those produced by a radio transmitter * Unintentional radiator, undesirable radio waves that are produced by an electronic device, such as a computer or video game console, as a consequence of its design Music and arts * ''Radiation'' (album), released in 1998, the tenth studio album by the British progressive rock band Marillion * "Radiation", a 1997 song by Feeder, from the album ''Polythene'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Radiation (disambiguation)」の詳細全文を読む スポンサード リンク
