Cherenkov radiation — Emission of radiation by a particle moving through an insulating medium faster than the speed of light in that medium.
Electromagnetic radiation — Stream of photons of a variety of different energies. At low frequencies, such as radio, it is common to regard the radiation as continuous rather than as photons.
Ionizing radiation — Stream of particles (photons or other particles) with sufficient energy to cause ionization of atoms or molecules.
Gravitational radiation — A predicted consequence of general relativity, however, it has not been directly observed.
Non-ionizing radiation — Any type of electromagnetic radiation that does not carry enough energy to ionize living material.
Particle radiation — Any kind of radiation in which the individual elements behave like particles.
Synchrotron radiation — Emission of radiation by a charged particle undergoing acceleration.
Thermal radiation — Process by which a hot object emits electromagnetic radiation; it is one of the three methods of heat flow.
Radiant energy is radiation emitted by a source into the surrounding environment.

Electromagnetic radiation is a propagating wave in space with electric and magnetic components. ... Ionizing radiation is a type of particle radiation in which an individual particle (for example, a photon, electron, or helium nucleus) carries enough energy to ionize an atom or molecule (that is, to completely remove an electron from its orbit). ... In physics, a gravitational wave consists of energy transmitted in the form of a wave through the gravitational field of space-time. ... Non-ionising radiation (or in American English non-ionizing radiation) refers to any type of electromagnetic radiation that does not carry enough energy to ionize living material - that is, to completely remove an electron from an atom or molecule. ... Particle radiation is the radiation of energy by means of small fast-moving particles that have energy and mass. ...

Biology
Adaptive radiation — a process in evolutionary biology by which one species becomes many in order to adapt to specific ecological niches.

Adaptive radiation describes the rapid speciation of a single or a few species to fill many ecological niches. ... Electroencephalography is the neurophysiologic exploration of the electrical activity of the brain by the application of electrodes to the scalp. ...
Meteorology
eta radiation refers to insolation in the ETA meteorological model
Radioactive decay — Set of various processes by which unstable atomic nuclei (nuclides) emit subatomic particles (radiation).

Aishwarya Raimay not be well known outside of Asia, but we think it's only a matter of time (and perhaps a role in a Western film) before India's jewel becomes the whole world's darling.
Aishwarya Rai is one of the most recognizable names and faces in her native land.
Aishwarya Rai was born in Mangalore, in the southern Indian state of Karnataka, on November1st, 1973.
Arti Rai is an expert in patent law, law and the biopharmaceutical industry, and health care regulation.
In the winter of 2007, Rai was the Hieken Visiting Professor in Patent Law at Harvard Law School.
Rai graduated from Harvard College, magna cum laude, with a B.A. in biochemistry and history (history and science), attended Harvard Medical School for the 1987-1988 academic year, and received her J.D., cum laude, from Harvard Law School in 1991.
