Contamination and Irradiation

Differentiate clearly between the scientific concepts of radioactive contamination and irradiation.
Define irradiation as the process of exposing an object to an external source of radiation without making the object itself radioactive.
Define radioactive contamination as the unwanted presence of radioactive substances on or within other materials, which continues to emit radiation over time.
Compare and contrast the specific health and environmental hazards associated with both contamination and irradiation.
