| physics | The science of nature, or of natural objects; that branch of science which treats of the laws and properties of matter, and the forces acting upon it; especially, that department of natural science which treats of the causes (as gravitation, heat, light, magnetism, electricity, etc) that modify the general properties of bodies; natural philosophy. Chemistry, though a branch of general physics, is commonly treated as a science by itself, and the application of physical principles which it involves constitute a branch called chemical physics, which treats more especially of those physical properties of matter which are used by chemists in defining and distinguishing substances. See: Physic. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| health physics | The science concerned with problems of radiation protection relevant to reducing or preventing radiation exposure, and the effects of ionizing radiation on humans and their environment. (12 Dec 1998) |
| tokamak physics experiment | <radiobiology> Smaller successor to TFTR at Princeton. Engineering design underway, construction scheduled to begin in FY 1995. (09 Oct 1997) |
| los alamos meson physics facility | <radiobiology> Physics research facility at Los Alamos National Lab, major site for U.S. Muon-catalysed fusion research in the 1980s. May be shut down soon. (09 Oct 1997) |
| abnormalities, radiation-induced | Congenital changes in the morphology of organs produced by exposure to ionizing or non-ionizing radiation. (12 Dec 1998) |
| accidents, radiation | Accidental dispersal of radioactive materials from a radiation source. Accidents at nuclear reactors can involve large groups of the population from dispersion of radioactivity into the environment and through fallout or a few individuals with high injurious doses. (12 Dec 1998) |
| acoustic radiation | The fibres that pass from the medial geniculate body to the transverse temporal gyri of the cerebral cortex by way of the sublentiform part of the internal capsule. Synonym: radiatio acustica. (05 Mar 2000) |
| acute radiation syndrome | <syndrome> A syndrome caused by exposure of the body to large amounts of radiation, (e.g., from certain forms of therapy, accidents, and nuclear explosions; it is divided into three major forms which are, in ascending order of severity, the haematogic, gastrointestinal, and central nervous system-cardiovascular forms; its clinical manifestations are divided into prodromal, latent, overt, and recovery stages. (05 Mar 2000) |
| adaptive radiation | <chemistry> The evolution of new speciesor sub-species to fill unoccupied ecological niches. (06 May 1997) |
| alpha radiation | <physics, radiobiology> The most easily absorbable type of radiation, it consists of a stream of alpha particles, doubly ionised helium nuclei which are electrically charged and produce intense ionisation in matter. Alpha radiation can be deflected in electromagnetic fields. (09 Oct 1997) |
| annihilation radiation | The radiation resulting when a positron from beta positive decay comes to rest. It encounters an electron, and they annihilate each other and convert their rest mass into two 0.51-MeV gamma rays emitted in exactly opposite directions. (05 Mar 2000) |
| background radiation | <radiobiology> Level of environmental radation due to background sources. Background sources can be natural, such as cosmic rays and natural radioactive elements (principally radon, but including other elements such as isotopes of potassium (which people get substantial amounts of in foods like bananas)). They can also be man-made, such as from fossil-fuel combustion, everyday leakage from nuclear activities, and leftover from atmospheric nuclear weapons tests. Background radiation is usually distinguished from acute radiation, such as from medical X-rays, nuclear accidents, radioisotope therapy, or other short-term doses. The man-made contribution to background radiation is quite small compared to the natural contribution, medical uses dominate human exposure to acute radiation. (09 Oct 1997) |
| beta radiation | <radiobiology> Radiant energy from a source of beta rays. (05 Mar 2000) |
| radiation | <radiobiology> Propagation of energy through space. In the context of this report, it is electromagnetic radiation (X-rays or gamma rays) or corpuscular radiation (alpha particles, electrons, protons, neutrons) capable of producing ionisation. (16 Dec 1997) |
| radiation anaemia | Hypoplastic anaemia sometimes occurring after high-level acute or low-level chronic exposure to ionizing radiation. (05 Mar 2000) |
