irradiation
Exposure to rays
Irradiation is exposure to radiation.
Food irradiation uses controlled doses to kill bacteria and extend shelf life.
Medical irradiation treats cancer by targeting tumors with radiation.
The term also covers exposure to light or other radiant energy: irradiation of the skin by ultraviolet rays.
Figuratively, irradiation can mean illumination or enlightenment, though this sense is rare.
