What does the term 'contamination' refer to in radiation protection?

The term 'contamination' in radiation protection specifically refers to the presence of radioactive materials on surfaces or within substances. This concept is crucial because contamination can occur in various environments, such as laboratories, medical facilities, or areas involved in nuclear research or energy production. It highlights a direct concern for safety, as radioactive materials can pose health risks when they come into contact with living organisms or when they are ingested or inhaled.

Contamination may result from spills, improper handling of radioactive materials, or even from natural sources. Recognizing this definition is important for implementing appropriate safety measures and decontamination procedures to minimize any potential exposure to hazardous radiation.

Cleaning processes, levels of radiation, and preventive methods are related to but distinct from the concept of contamination itself. Understanding contamination helps professionals in radiation protection effectively assess and mitigate risks associated with radioactive materials in various settings.
