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 by X-ray is similar to irradiation by gamma rays in that less energetic packets of light (X-rays) are used. X-rays are generated by colliding accelerated electrons with a dense material (this process is known as bremsstrahlung-conversion), and therefore do not necessitate the use of radioactive materials.rradiation is used to delay the ripening of fruits and the sprouting of vegetables by slowing down the speed at which enzymes produced by the food can change the food. By halting or slowing down spoilage and slowing down the ripening of food, irradiation prolongs the shelf life of goods.
