A requirement for X-ray control labeling includes legibility and visibility. What does this entail?

• A. Legible and in Clear View
• B. Hidden Behind the Unit
• C. Only Viewable in Digital Form
• D. Optional If the Operator Is Experienced

Answer: (A)

The main idea here is that X-ray control labeling must be readable and easy to see. Legibility means the text or symbols on the control panel are clear and large enough, with good contrast and a simple, consistent font so you can quickly read settings, warnings, and instructions. Visibility means those labels are placed where you can read them without having to move the equipment, under typical room lighting, and without glare or obstruction.

Why this matters: you need to be able to verify exposure settings and safety notices at a glance before firing the X-ray unit. If labels are hard to read or hidden, you risk selecting the wrong timer, kVp, or exposure settings, which can lead to unnecessary radiation exposure to the patient or operator.

So the correct idea is that labeling should be legible and clearly visible—not hidden behind the unit, not limited to digital displays only, and not optional.
