Irradiation
Irradiation is the process by which an object is exposed to
radiation. The exposure can originate from various sources, including natural sources. Most frequently the term refers to
ionizing radiation, and to a level of radiation that will serve a specific purpose, rather than
radiation exposure to normal levels of
background radiation. The term irradiation usually excludes the exposure to non-ionizing radiation, such as infra-red, visible light, microwaves from cellular phones or electromagnetic waves emitted by radio and TV receivers and power supplies.
