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 process, considered controversial by many, (including natural food advocates) of using radiation to kill bacteria and other germs in food products, in order to lengthen the shelf-life of the product.
The impinging of radiation on an object or surface.
The process of bombarding a gemstone with X-rays, gamma rays or streams of subatomic particles in order to change the stone's color.
is a process of food preservation using either electron beams or high-speed gamma rays to affect the food. It destroys some vitamins and enzymes in the food, creates free radicals which may react with cell membranes of the human body causing them to function poorly, and may leave a trace amount of radioactivity in certain foods.
The process of causing radiation to interact with matter.
The use of radiation in food processing to lengthen shelf life by eliminating pathogenic microorganisms. It is considered a food additive and is regulated by the FDA's
The bombarding of atoms with nuclear particles to change the structure of the nucleus and produce radioactive atoms. Fuel which has been in a reactor is often called "irradiated" because it has been bombarded with neutrons and has become radioactive.
A gemstone enhancement process, irradiation uses high energy, sometimes followed by heating, to alter gemstone color. Diamonds are sometimes irradiated to produce or enhance various colors. Other gemstones may also be treated using this method.

Treatment with electromagnetic radiation.
The use of radiation, regulated by the FDA, to eliminate or destroy disease-causing microorganisms.
Irradiation is a method of preservation which uses ionizing radiation to destroy or inactivate many of the microorganisms which cause meat to spoil and cause food-borne illnesses.
incident energy per unit area of incident surface, found by integration of irradiance over a specified time interval (usually an hour or a day) [Wh/m2] [MJ/m2] Bestrahlung
Exposure to radiation of any kind, especially ionizing radiation.
Exposure to radiant energy, such as heat, X-rays, or light.
the condition of being exposed to radiation
(medicine) the treatment of disease (especially cancer) by exposure to radiation from a radioactive substance
Process in which food is exposed to radiant energy.
Replace existing definition with: 1) The process of transmitting radiant energy in the form of waves or particles, such as visible light, infra-red light, ultraviolet light, X-rays, or gamma rays. Ionizing radiation is often used to kill microorganisms in sterilization procedures. 2) The sending forth of light, short radio waves, ultraviolet or x-rays, or any other rays for treatment or diagnosis or for other purpose.
Another term for radiation therapy.
high-energy rays used to kill diseased cells before or during transplant.
Exposing gemstones to radioactive rays from x-rays or other material to change or enhance the original color. Blue topaz is always irradiated, for example.
the application of radiation for various purposes, including reducing levels or killing microorganisms and mould in foods, killing insects and pests that infest certain foods, and sterilizing food for specific medical applications.
Irradiation is the act of being exposed to radiation.
The total amount of solar radiation direct, diffused and reflected-striking a surface exposed to the sky.
The use of ionizing radiation for the preservation of food
The act of being exposed to radiation. This may have an effect on several gemstones by altering their color.
The use of radiation to change a gem's color. Frequently used with certain gems and safe to humans.
As applied to plastics, refers to bombardment with a variety of subatomic particles, generally alpha-, beta-, or gamma-rays. Atomic irradiation has been used to initiate polymerization and copolymerization of plastics and in some cases to bring about changes in the physical properties of a plastic material.
A food preservation process that utilizes radiation to control bacteria growth and increase shelf-life.
Subjecting plastics or other compounds to radiant energy to cure or produce some change in the material, or to test the results. Cross-linking of thermoplastics is accomplished in this way. Some medical applications require parts to be irradiated with gamma rays for sterilization.
Exposure to radiation. Meat is sometimes irradiated to kill micro-organisms and reduce the number of microbes present due to unsanitary practices, but this process alters the nutritional quality and creates new chemicals that can be harmful to the humans who consume the meat. Many believe that there has not been enough testing to know whether irradiated food is safe for humans. For more information on this topic, visit Public Citizen's food irradiation page.
The exposure to or application of radiation as X-rays or alpha particles.
Therapeutic application of radiation to a patient
The process of exposing to radiation.
Subjection to ionising radiation.
Food irradiation is exposure to ionising radiation resulting in a reduction in the levels of bacteria. It can also be used to kill pathogenic organisms, reduce spoilage and delay ripening and sprouting in food.
Treatment or therapy by exposure to radiation.
The process of exposing products or materials to ionizing rays of energy.
treatment with x-rays or other radioactive substances. See TBI .
The use of high-energy radiation from x-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy) or from materials called radioisotopes. Radioisotopes produce radiation and can be placed in or near the tumor or in the area near cancer cells. This type of radiation treatment is called internal radiation therapy, implant radiation, interstitial radiation, or brachytherapy. Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. Irradiation is also called radiation therapy, radiotherapy, and x-ray therapy.
a process involving the use of low levels of radiation to reduce the presence of disease causing agents, for example during the processing of food products.
Application of radiation (as X rays or ultraviolet light) especially for therapeutic purposes.
Radiation therapy; treatment by ionizing radiation.
process of preserving food by exposing it to gamma radiation in an effort to kill harmful bacteria which it might contain
Treatment by ionizing radiation, such as x-rays, or radioactive sources such as radioactive iodine seeds. See radiation therapy.
Exposure to radiation of wavelengths shorter than those of visible light (gamma, x-ray, or ultra- violet), for medical purposes, to sterilize milk or other foodstuffs, or to induce polymerization of monomers or vulcanization of rubber.
Radiation that is incident on a surface.
Treated with ultra violet light or another high energy ray.
The process by which some substance, such as a food, is exposed to some form of radiation, such as gamma rays or X rays.
Irradiation is the process by which an item is exposed to radiation. The exposure can be intentional, sometimes to serve a specific purpose, or it can be accidental. In common usage the term refers specifically to ionizing radiation, and to a level of radiation that will serve that specific purpose, rather than radiation exposure to normal levels of background radiation or abnormal levels of radiation due to accidental exposure.
