Contamination in radiation safety specifically refers to the presence of radioactive material on surfaces, including equipment, clothing, and skin. This can occur when radioactive substances are inadvertently spread from their source, leading to potential risks for individuals and the environment. Unlike exposure, which focuses on the radiation received by personnel, contamination emphasizes the physical presence of radioactive materials that can pose a risk through direct contact or inhalation. Managing contamination is crucial for maintaining safety and preventing the spread of radioactive materials, emphasizing the importance of decontamination processes and monitoring procedures in environments where radiation is present.
