What does “contamination” refer to in radiation safety?

In the context of radiation safety, "contamination" specifically refers to the presence of radioactive material on surfaces. This can include contamination on skin, clothing, equipment, or environmental surfaces. When radioactive substances settle on these surfaces, they can potentially pose health risks to individuals who come into contact with them or who are exposed to radiation emitted from these contaminated items.

Identifying contamination is crucial for maintaining safety in environments where radioactive materials are present. It requires careful monitoring and decontamination procedures to reduce exposure risks. This distinction illustrates the importance of managing and mitigating contamination in radiation safety protocols, thereby protecting public health and safety.
