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
The major source of radiation exposure is the radioactive material on the ground, the immediate effects can be lethal, you can develop acute radiation syndrome which you can die from in a few minutes or hours. There are also lots of delayed syndromes where you may not die until a few weeks and even long-term effects like cancer risks.
Even if some of the radioactive materials 'leaked' or still 'leak' from the ship, this radioactivity will be diluted very quickly in the water reducing the concentration substantially, in addition, the radiation emitted by the radioactive materials on the ship will not travel very far as the water is an excellent shield.
After a number of other tests, I returned to Mayo and had a lumpectomy on the right breast which involved the removal of the cancer, in May, I completed a course of radiation treatment, and after additional follow-up visits, it was determined in August that the treatment went well.
For most patients, it should technically be possible to avoid delivering radiation to this newly discovered location of the salivary gland system in the same way we try to spare known glands, our next step is to find out how we can best spare these new glands and in which patients. If we can do this, patients may experience less side effects which will benefit their overall quality of life after treatment.
Getting up in the morning, very early, 6:30 a.m., and going in for radiation -- he doesn't complain, he just gets up, pulls up his socks and his boots, and in he goes. I'm really proud of him.
