Irradiation

Process by which an organ or tissue is exposed to radiation.

The use of high-energy radiation from x-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 method of sterilising and disinfecting foods using ionising radiation (X-rays or y-rays) to kill microorganisms and insects. Also used to inhibit sprouting of potatoes.

Sterilization utilizing high-energy electromagnetic radiation.

The process of spreading from a centre, as e.g., nerve impulses do.

The use of radiation to treat people or to kill bacteria in food.

Exposure to heat, light, X ray, or other form of radiant energy for diagnostic or therapeutic purposes.

Medical irradiation is used for diagnostic or therapeutic purposes and may involve X rays or radioactive isotopes.

Exposure to radiation. Medical irradiation is used for diagnostic or therapeutic purposes and may involve X rays or radioactive isotopes.

The therapeutic application of electromagnetic radiation (usually alpha, beta, gamma, or X-rays) to a particular structure.

The use of naturally occurring isotopes, or artificially produced X-rays, in the killing of tumour cells. The amount of radiation is the adsorbed dose; the SI unit is the gray (Gy). Different tumours seem to be particularly sensitive to radiation: radiotherapy plays an important role in the management of germ-cell tumours and lymphomas. Many head and neck tumours, gynaecological cancers, and localized prostate and bladder cancers are curable with radiotherapy. It may be used to reduce the pain for example, from bone metastases.

The diagnostic or therapeutic application of x-ray photons, nuclear particles, highspeed electrons, ultraviolet rays, or other forms of radiation to a patient.

Treatment with gamma rays, x rays, or high-voltage electrons to kill pathogens and, in the case of food, to increase shelf life.

Exposure of foods like grains, flour, fruits, and vegetables to low doses of ionized radiation or other forms of electromagnetic radiation in order to prolong their shelf life.

The irradiation of a substance, item, or individual with ionizing radiation.
