Radiation Safety Practice Exam

What is the purpose of wet mopping in radiation safety?

1. To clean solid contamination

2. To decontaminate oily surfaces

3. To clean liquid contamination

4. To spread contaminants evenly

The correct answer is: To clean liquid contamination

Wet mopping is utilized in radiation safety specifically for cleaning liquid contamination. The primary goal of wet mopping is to effectively collect and contain radioactive materials that are in a liquid state, which can be more challenging to manage than solid contaminants. By using a damp mop, the moisture helps to capture particles and prevent them from becoming airborne, thereby minimizing the risk of inhalation or further spread of contaminants. This method is particularly effective because the liquid acts as a binding agent, allowing for efficient removal of radioactive substances from surfaces. Wet mopping is a common practice in areas where spills may occur, ensuring that contaminated surfaces are restored to a safe condition. While cleaning solid contamination and addressing oily surfaces are important, they typically require different methods, such as dry sweeping or the use of specialized cleaning agents.
