WebA process which alters the energy balance of the Earth-atmosphere system is known as a radiative forcing mechanism. These may include variations in the Earth’s orbit around the Sun, solar radiation, volcanic activity and atmospheric composition. Associating a particular cause with a particular change, however, is extremely difficult. WebA wide variety of reactions occur in response to irradiation in the different organs and tissues of the body. Some of the reactions occur quickly, while others occur slowly. The killing of cells in affected tissues, for example, may be detectable within minutes after exposure, whereas degenerative changes such as scarring and tissue breakdown ...
