Which statement about step-off pads is true?

• A. Contamination must be controlled; it could spread to car or home or public places
• B. Step-off pads have no function
• C. Step-off pads measure dose rate
• D. Step-off pads are used for wear testing

Answer: (A)

Step-off pads are a contamination-control measure used at the exit from a controlled area. They provide a designated place to step off and remove or wipe away contamination on footwear, catching particles on the pad so they are not carried into a car, home, or public spaces. This prevents spreading radioactive contamination beyond the controlled area and helps protect people outside and the environment. They are not used to measure dose rate, nor for wear testing; their purpose is to stop the spread of contamination.
