What does "contamination" mean in the context of radiation safety?

In the context of radiation safety, "contamination" refers to the presence of radioactive material where it is not supposed to be. This definition is crucial because contamination can occur on surfaces, in the environment, or on personnel, leading to potential exposure to radiation. The presence of radioactive substances in unexpected places can pose health risks to individuals who may inadvertently come into contact with them or inhale them, thereby increasing the likelihood of radiation exposure.

Understanding this definition is vital for implementing effective safety protocols and containment procedures in environments where radioactive materials are used or stored. It highlights the importance of monitoring and controlling radioactive materials to ensure that they remain within designated areas, thereby minimizing the risk of harmful exposure to radiation for both workers and the general public.
