Which method is effective for spot contamination removal in radiation situations?

• A. Adhesive tape
• B. Heavy-duty scrubbing
• C. Blowing air
• D. High-pressure washing

Answer: (A)

Using adhesive tape for spot contamination removal in radiation situations is effective due to its ability to lift and trap surface contamination without spreading it further. Adhesive tape provides a controlled means to remove radioactive particles from surfaces, allowing for a localized cleanup where radioactivity is present. This method minimizes the risk of resuspending particles into the air or moving contamination to cleaner areas, which can happen with more aggressive cleaning methods. Other methods, such as heavy-duty scrubbing, may not be suitable as they can potentially spread contamination or damage surfaces, making it harder to verify the effectiveness of the cleanup. Blowing air can inadvertently cause contaminants to become airborne, leading to further spread and increased inhalation or exposure risks. High-pressure washing is similarly problematic, as it can disperse contaminated particles into the environment and does not guarantee thorough removal, especially on porous or irregular surfaces. Therefore, adhesive tape remains a preferred choice for effective and controlled spot contamination removal.
