Which of the following must be monitored for radiation leakage?

Monitoring radiation leakage is crucial to ensure that equipment designed to protect workers and patients from radiation exposure is functioning properly. Dental x-ray machines, in particular, must be regularly monitored for leakage because they emit ionizing radiation during operation. If there is any leakage, it can pose a risk to both operators and patients who are in proximity during an x-ray procedure.

The design and operation of dental x-ray machines involve careful shielding to prevent unnecessary exposure, so verifying that no radiation escapes the designated areas is essential. Routine checks for leakage can help maintain the safety and effectiveness of the machine, ensuring compliance with safety regulations.

Protection barriers, lead aprons, and control panels are also important components that help shield individuals from radiation, but they are typically not monitored for radiation leakage in the same direct manner as dental x-ray machines. Instead, lead aprons and barriers are inspected for physical condition and integrity, while control panels are evaluated for their operational effectiveness rather than radiation emissions.
