irradiation. noun. 1  The act of exposing or the condition of being exposed to radiation. 2  The use or application of ionizing radiation, especially in medical treatment and for the sterilization or preservation of food.
Irradiation is most useful in four areas. Preservation. Irradiation can be used to destroy or inactivate organisms that cause spoilage and decomposition, thereby extending the shelf life of foods. It is an energy-efficient food preservation method that has several advantages over traditional canning.he irradiation process involves passing food through an irradiation field; however, the food itself never contacts a radioactive substance. Also, the ionizing radiation used by irradiators is not strong enough to disintegrate the nucleus of even one atom of a food molecule.
