What measures ensure personnel safety around X-ray equipment (interlocks, shielding, alarm systems)?

• A. Shielding barriers, protective housing, badge monitoring; door interlocks; warning lights and audible alarms; safety procedures and training.
• B. Badge monitoring only.
• C. No interlocks or alarms are necessary.
• D. Shielding barriers alone are sufficient.

Answer: (A)

Layered protections around X-ray equipment are designed to prevent exposure and quickly alert workers if something goes wrong. Protective housing and shielding barriers physically contain the radiation and limit where it can go; interlocks prevent the tube from energizing if an access door or panel is open; warning lights and audible alarms signal when X-ray production is active; badge monitoring tracks personnel doses to ensure exposure stays within limits; safety procedures and training ensure everyone uses the equipment correctly and responds appropriately to alarms. Together, these measures provide active prevention, immediate warning, and ongoing dose monitoring, which is why this comprehensive approach is the best choice. Relying only on badge monitoring misses real-time protection; having no interlocks or alarms eliminates a crucial safety control; shielding alone doesn’t manage access or ensure proper procedures.
