Irradiation vs. Radiation — What's the Difference?

The process of illuminating something with light.

The emission of energy as electromagnetic waves or as moving subatomic particles.

The application of radiation to a material to alter its properties.

Energy transmitted through space in the form of waves or particles.

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

The process of emitting energy in the form of waves or particles.

The act of exposing or the condition of being exposed to radiation.

Waves or particles (like alpha, beta, gamma) given off by unstable atoms.

The use or application of ionizing radiation, especially in medical treatment and for the sterilization or preservation of food.

Ionizing or non-ionizing energy emitted from a source.

An act of irradiating, or state of being irradiated.

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.

(obsolete) illumination; irradiance; brilliance.

The act or process of radiating

Mental light or illumination.

Emission or propagation of energy in the form of waves or particles.

(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.

Energy radiated or transmitted in the form of waves or particles.

(uncountable) a process of sterilization whereby radiation is passed through a bag containing food, utensils, etc., to sterilize the contents. Category:en:Radioactivity

A stream of particles or electromagnetic waves emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay.

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 .

The act of exposing or the condition of being exposed to such energy.

Illumination; irradiance; brilliancy.

The application of such energy, as in medical treatment.

Fig.: Mental light or illumination.

(Anatomy) Radial arrangement of parts, as of a group of nerve fibers connecting different areas of the brain.

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.

Adaptive radiation

The condition of being exposed to radiation

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

A column of light (as from a beacon)

The process of radiating waves or particles.

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

The transfer of energy via radiation.

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

Radioactive energy.

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

A rapid diversification of an ancestral species into many new forms.

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

The act of radiating, or the state of being radiated; emission and diffusion of rays of light; beamy brightness.

The exposure of an object or substance to radiation.

The shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of heat.

The use of radiation for therapeutic purposes, especially in medicine.

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

A method used to preserve food by reducing or eliminating microorganisms and insects.

The act of spreading outward from a central source

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;

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

The spread of a group of organisms into new habitats

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

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

Only ionizing radiation, like X-rays, poses significant health risks at high levels.

Yes, sunlight is a form of electromagnetic radiation.

Irradiation targets and kills cancer cells, slowing or stopping tumor growth.

It means the food has been exposed to radiation to kill bacteria and extend its shelf life.

Yes, they emit non-ionizing radiation, but at levels considered safe for regular use.

No, the process of irradiation does not make food radioactive.

Yes, irradiated food is considered safe and retains its nutritional value.

Radiation is often measured in units like rads, rems, sieverts, or grays.

Common sources include sunlight, radon, and certain household appliances.

Irradiation in food kills pathogens and extends shelf life.

Generally, irradiation has minimal to no effect on the taste of food.

Irradiation damages the DNA of microorganisms, rendering them inactive or dead.

A small amount of radioactive material helps detect smoke particles in the air.

Yes, due to naturally occurring radioactive atoms in our body, we emit a small amount of radiation.

Radiation therapy is a type of irradiation used to treat diseases like cancer.
