radiation
Radiation is the emission or transmission of energy in the form of particles or waves through space or through a material medium. This includes electro-magnetic radiation such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation, as well as particle radiation such as alpha radiation, beta radiation, and neutron radiation.
Webster Dictionary
Radiationnoun
the act of radiating, or the state of being radiated; emission and diffusion of rays of light; beamy brightness
Radiationnoun
the shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat
Etymology: [L. radiatio: cf. F. radiation.]

Radiation
In physics, radiation is a process in which energetic particles or energetic waves travel through a vacuum, or through matter-containing media that are not required for their propagation. Waves of a mass filled medium itself, such as water waves or sound waves, are usually not considered to be forms of "radiation" in this sense. Radiation can be classified as either ionizing or non-ionizing according to whether it ionizes or does not ionize ordinary chemical matter. The word radiation is often colloquially used in reference to ionizing radiation, but the term radiation may correctly also refer to non-ionizing radiation as well. The particles or waves radiate from a source. This aspect leads to a system of measurements and physical units that are applicable to all types of radiation. Because radiation expands as it passes through space, and as its energy is conserved, the power of all types of radiation follows an inverse-square law in relation to the distance from its source. Both ionizing and non-ionizing radiation can be harmful to organisms and can result in changes to the natural environment. In general, however, ionizing radiation is far more harmful to living organisms per unit of energy deposited than non-ionizing radiation, since the ions that are produced, even at low radiation powers, have the potential to cause DNA damage. By contrast, most non-ionizing radiation is harmful to organisms only in proportion to the thermal energy deposited, and is conventionally considered harmless at low powers that do not produce a significant temperature rise. Ultraviolet radiation in some aspects occupies a middle ground, as it has some features of both ionizing and non-ionizing radiation. Although nearly all of the ultraviolet spectrum that penetrates the Earth's atmosphere is non-ionizing, this radiation does far more damage to many molecules in biological systems than can be accounted for by heating effects. These properties derive from ultraviolet's power to alter chemical bonds, even without having quite enough energy to ionize atoms.
U.S. National Library of Medicine
Radiation
Emission or propagation of electromagnetic energy (waves/rays), or the waves/rays themselves; a stream of electromagnetic particles (electrons, neutrons, protons, alpha particles) or a mixture of these. The most common source is the sun.
The Standard Electrical Dictionary
Radiation
The traveling or motion of ether waves through space. [Transcriber's note: The modern term corresponding to this definition is photons. The modern concept of radiation also includes particles-- neutrons, protons, alpha (helium) and beta (electrons) rays and other exotic items.]

Examples of Radiation in a Sentence
These experimental animal studies are but one approach to understanding whether exposures to radiofrequency radiation pose a risk to human health.
Most are pretty efficient at blocking UV radiation, if you are using a mask, I'm a big fan of mineral sunscreens and stick sunscreens... the stick adheres to skin a little bit better and doesn't get as runny as liquid.
Until radiation therapy is permitted, until we can develop a bone marrow transplant department here, some kids do still have to travel outside for treatment.
A great example of that would be the Fukushima disaster-- where there was radiation. It was extremely dangerous for humans to go in. And what would have been really great is if we could have sent robots in to do something as simple as turn a valve.
If we personalise treatment according to the radiation dose delivered to the tumour, then we should have a better outcome, i think it will have a huge impact.
