Radiation Guide, Meaning , Facts, Information and Description
Radiation generally means the transmission of objects or information from a source into a surrounding medium or destination.Within physics, related concepts are:
- Ionizing radiation is a stream of particles (photons or other particles) with sufficient energy to cause ionization of atoms or molecules.
- Non-ionizing radiation does not have this sufficient energy.
- Electromagnetic radiation: light is the visible form; thermal radiation is (usually) the heat form.
- Gravitational radiation
- Particle radiation is any kind of radiation in which the individual elements behave like particles, for example fast or slow Neutron radiation.
- Cherenkov radiation is the emission of radiation by a particle moving through an insulating medium faster than the speed of light in that medium.
- Synchrotron radiation is the emission of radiation by an charged particle undergoing acceleration. This happens, for example, if the particle moves in a circle, as in a synchrotron.
Radiation is sometimes also used, inaccurately, to refer to radioactive contamination, the release of radioactive isotopes into the environment. These isotopes then release ionizing radiation, which can be especially severe if the isotopes have been taken up by plants, animals or humans, since the isotopes then release their ionizing radiation from inside the organism.
