“radiation”的概念、定义、翻译、参考文献-科学参考

radiation

Physics

1. Energy travelling in the form of electromagnetic waves or photons.

2. A stream of particles, especially alpha- or beta-particles from a radioactive source or neutrons from a nuclear reactor.

Astronomy

1. Energy propagating in the form of electromagnetic waves or photons (see electromagnetic radiation).

2. A stream of particles, most commonly protons and electrons.

Space Exploration

The emission of radiant energy as particles or waves—for example, heat, light, alpha particles, and beta particles. An astronaut's exposure to radiation must be monitored constantly with dosimeters. Dangerous amounts of radiation have apparently not been encountered yet on space missions. Crewed spacecraft around the Earth usually orbit below the Van Allen radiation belts to avoid radiation, but intergalactic cosmic rays and solar flares are of concern.

Chemistry

1. Energy travelling in the form of electromagnetic waves or photons.
2. A stream of particles, especially alpha- or beta-particles from a radioactive source or neutrons from a nuclear reactor.

Chemical Engineering

1. The transfer of energy by electromagnetic waves through a transmitting medium. The radiation may be absorbed, transmitted, or reflected by a receiving body although only the absorbed radiation is converted to heat.

2. Emission of particles, especially alpha or beta particles from a radioactive source or neutrons from a nuclear reactor.

Electronics and Electrical Engineering

Any form of energy that is propagated as waves or streams of charged particles. See electromagnetic radiation.

Biology

1. (in physics) Energy travelling in the form of electromagnetic waves or photons. See electromagnetic spectrum.
2. (in physics) A stream of particles, especially alpha- or beta-particles from a radioactive source or neutrons from a nuclear reactor. See also background radiation.
3. (in evolution) See adaptive radiation.

Geology and Earth Sciences

Any form of emitted wave phenomena, usually the electromagnetic spectrum, sound, or heat.

Geography

Energy travelling in the form of electromagnetic waves: X-rays, ultraviolet, visible, infra-red, microwaves, or radio waves. In urban areas, a reduction in the sky view factor decreases the loss of terrestrial radiation thereby contributing to the creation of urban heat islands (Grimmond (2007) Geog. 30, 3).
