What does the term "contamination" refer to in radiation safety?

The term "contamination" in radiation safety specifically refers to the unintended presence of radioactive material on surfaces or in the environment. This can occur in various settings, such as laboratories, industrial facilities, or areas near nuclear reactors, where radioactive isotopes may inadvertently settle on equipment, floors, or air without proper control measures in place.

Contamination is a critical concern in radiation safety because it poses health risks to personnel and can lead to environmental pollution. When radioactive materials are present where they shouldn't be, they can be ingested or inhaled by individuals, increasing the risk of radiation exposure and potential health effects.

Effective monitoring and decontamination procedures are vital in managing this issue. Detecting contamination early allows for appropriate steps to be taken to minimize exposure and properly dispose of or clean up radioactive materials to ensure safety for all. This definition distinctly clarifies why contamination is separate from controlled exposure, accidental releases, and the management of radioactive waste, which have different safety protocols and implications.
