Irradiation vs. Radiation

Irradiationnoun

An act of irradiating, or state of being irradiated.

Irradiationnoun

(obsolete) illumination; irradiance; brilliance.

Irradiationnoun

mental light or illumination.

Irradiationnoun

(obsolete) The apparent enlargement of a bright object seen upon a dark ground, due to the fact that the portions of the retina around the image are stimulated by the intense light; as when a dark spot on a white ground appears smaller, or a white spot on a dark ground larger, than it really is, especially when a little out of focus.

Irradiationnoun

(uncountable) a process of sterilisation whereby radiation is passed through a bag containing food, utensils, etc., to sterilise the contents.

Irradiationnoun

Act of irradiating, or state of being irradiated; as, irradiation of foods with X-rays can preserve their freshness by killing the bacteria that cause spoilage .

Irradiationnoun

Illumination; irradiance; brilliancy.

Irradiationnoun

Fig.: Mental light or illumination.

Irradiationnoun

The apparent enlargement of a bright object seen upon a dark ground, due to the fact that the portions of the retina around the image are stimulated by the intense light; as when a dark spot on a white ground appears smaller, or a white spot on a dark ground larger, than it really is, esp. when a little out of focus.

Irradiationnoun

the condition of being exposed to radiation

Irradiationnoun

a column of light (as from a beacon)

Irradiationnoun

(physiology) the spread of sensory neural impulses in the cortex

Irradiationnoun

the apparent enlargement of a bright object when viewed against a dark background

Irradiationnoun

(Pavolvian conditioning) the elicitation of a conditioned response by stimulation similar but not identical to the original stimulus

Irradiationnoun

(medicine) the treatment of disease (especially cancer) by exposure to radiation from a radioactive substance

Irradiation

Irradiation is the process by which an object is exposed to radiation. The exposure can originate from various sources, including natural sources.

Radiationnoun

The shooting forth of anything from a point or surface, like diverging rays of light.

Radiationnoun

The process of radiating waves or particles.

Radiationnoun

The transfer of energy via radiation (as opposed to convection or conduction).

Radiationnoun

Radioactive energy.

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.

Radiationnoun

energy that is radiated or transmitted in the form of rays or waves or particles

Radiationnoun

the act of spreading outward from a central source

Radiationnoun

syndrome resulting from exposure to ionizing radiation (e.g., exposure to radioactive chemicals or to nuclear explosions); low doses cause diarrhea and nausea and vomiting and sometimes loss of hair; greater exposure can cause sterility and cataracts and some forms of cancer and other diseases; severe exposure can cause death within hours;

Radiationnoun

the spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay

Radiationnoun

the spread of a group of organisms into new habitats

Radiationnoun

a radial arrangement of nerve fibers connecting different parts of the brain

Radiationnoun

(medicine) the treatment of disease (especially cancer) by exposure to radiation from a radioactive substance

Radiation

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle radiation, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy) acoustic radiation, such as ultrasound, sound, and seismic waves (dependent on a physical transmission medium) gravitational radiation, radiation that takes the form of gravitational waves, or ripples in the curvature of spacetimeRadiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles.
