What is a common simple method for decontamination?

1. Using a vacuum to remove contamination

2. Cleaning with swabs

3. Applying a chemical solvent

4. Using steam-based cleaners

The correct answer is: Cleaning with swabs

Cleaning with swabs is a common and straightforward method for decontamination because it allows for targeted removal of radioactive contaminants from surfaces. Swabs can be used to physically capture and remove particulate contamination, ensuring that contaminated areas are thoroughly cleaned. This method is particularly effective for small or localized contaminations where precision is needed, and it is easy to implement in various settings. Using swabs also enables the operator to analyze the swabbed material for contamination levels, facilitating a more accurate assessment of the decontamination process. It can be utilized for different surface types and in areas that are too delicate for more aggressive cleaning techniques. In contrast, other methods while effective in certain contexts may not be as versatile or practical. For example, using a vacuum might not effectively address some types of contamination that adhere stubbornly to surfaces. Applying chemical solvents may introduce additional hazards, especially if the solvent itself is toxic or reactive. Steam-based cleaners might be less suitable for sensitive surfaces and also require specific handling to avoid heat damage or condensation issues. Thus, the simplicity and effectiveness of using swabs makes it a widely accepted technique for decontamination.
