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.
Most living tissue contains at least 70 percent water by mass. When living tissue is irradiated, most of the energy of the radiation is absorbed by water molecules. Thus, it is common to define ionizing radiation as radiation that can ionize water, a process requiring a minimum energy of 1216 kJ/mol.
