ASNT Industrial Radiography Radiation Safety Practice Test

What critical information must be visibly stated on a control panel of an X-ray system?

1. Authorized Use Only

2. Caution: X-rays produced when energized

3. Wear Protective Gear

4. Secure All Equipment

The correct answer is: Caution: X-rays produced when energized

The critical information that must be visibly stated on the control panel of an X-ray system is "Caution: X-rays produced when energized." This warning is essential for ensuring the safety of individuals operating or working near the X-ray equipment. It informs users that the machine generates X-rays only when it is powered on and operational, emphasizing the potential radiation exposure risks involved. The presence of this label serves as a necessary reminder to operators and nearby personnel to remain vigilant about the state of the machine. This is particularly significant in environments where multiple people might be present, as it helps to prevent accidental exposure to radiation. Properly warning users allows for safety measures to be implemented, such as avoiding unnecessary exposure and ensuring that safety protocols are followed when the X-ray system is active. While other labels may carry useful safety information, none carry the same level of immediate caution regarding radiation production during operation. Therefore, the specification of the X-ray generation status when energized is crucial for operational safety and radiation protection.
