Radiation Safety Practice Exam

Which is a characteristic of effective damp wiping?

1. Using a damp towel to spread contaminants

2. Changing wiping surfaces frequently

3. Wiping only high-touch surfaces

4. Using the same towel for multiple areas

The correct answer is: Changing wiping surfaces frequently

An effective damp wiping process is crucial for controlling contamination, especially in environments where radiological safety is a concern. Changing wiping surfaces frequently is essential because it prevents the transfer of contaminants from one area to another. Each surface can collect different types or amounts of contaminants, so using a fresh or clean wiping surface ensures that removal is maximized and that you do not inadvertently spread hazardous materials. When surfaces are changed out often during the wiping process, it enhances the effectiveness of contamination control by ensuring any contaminants picked up on a towel are not redeposited elsewhere. This practice contributes significantly to maintaining a safe environment, especially when dealing with radioactive materials or potentially harmful substances.
