What does the material suggest about the role of monitoring in protection?

• A. It provides direct protection
• B. It offers no protection and is only an indicator
• C. It eliminates exposure completely
• D. It reduces exposure by automatic calibrations

Answer: (B)

Monitoring in radiation protection is primarily a diagnostic tool that reveals the levels of exposure rather than providing protection by itself. Personal dosimeters and area monitors show how much radiation has been received or how strong the radiation environment is, so you can assess risk, verify that shielding and procedure controls are working, and trigger protective actions when limits are approached. The actual protection comes from engineered controls like shielding, limiting time near sources, maintaining distance, and using appropriate containment and PPE. A device that merely indicates exposure cannot eliminate or automatically reduce it; it guides the protective measures you implement.
