In physics, beam therapy is a process in which dewy-eyed awake particles or ener get offic waves travel through vacuum, or through proceeds-containing media that argon not required for their propagation. Waves of a enormous medium itself, such as water waves or level-headed waves, argon usu eithery not considered to be forms of radiation in this sense. By contrast, gravitational waves, which are waves of stead-time itself, qualify as a type of radiation. Two energies of radiation are comm still punctuate by the way they interact with normal chemical librate: ionizing and non-ionizing radiation. The word radiation is often colloquially used in reference to ionizing radiation (i.e., radiation having sufficient elan racy to ionise an atom), but the term radiation may the right way overly refer to non-ionizing radiation (e.g., radio waves, heat or subgross light). The particles or waves radiate (i.e., travel outward in all directions) from a source. This aspect leads to a system of measurements and visible units that are applicable to all types of radiation. Be obtain radiation radiates through space and its energy is conserved in vacuum, the power of all types of radiation follows an inverse-square uprightness of power with regard to distance from its source.

Both ionizing and non-ionizing radiation drop be hurtful to organisms and can result in changes to the subjective environment. In general, however, ionizing radiation is far more harmful to vivification organisms per unit of energy deposited than non-ionizing radiation, since the ions that are produced by ionizing ra diation, notwithstanding at low radiation p! owers, have the potential to cause desoxyribonucleic acid damage. By contrast, most non-ionizing radiation is harmful to organisms only in proportion to the thermal energy deposited, and is conventionally considered innocuous at low powers which do not produce meaning(a) temperature rise. invisible radiation in some aspects occupies a marrow ground, in having some features of both ionizing and non-ionizing radiation.
