What does “contamination” mean in the context of radiation safety?

In the context of radiation safety, "contamination" specifically refers to the presence of radioactive material in unintended areas. This can occur when radioactive substances are released or spread from their controlled environments, leading to unintended exposure of surfaces, equipment, or individuals to radioactive materials. Contamination can happen through various means, such as spills, improper handling, or accidents, and it poses a significant risk to health and safety because it can lead to radiation exposure in areas where it should not be present.

Understanding contamination is critical for radiation safety personnel, as it guides the implementation of proper clean-up procedures, decontamination methods, and preventive measures to protect not only workers but also the surrounding environment from radiation hazards. Identifying and addressing contamination is fundamental to maintaining safe work practices in environments where radioactive materials are used, stored, or transported.
