Where must technique charts be posted for units without built-in settings?

• A. In the Waiting Room
• B. At Each Control Panel
• C. On the Device Storage
• D. In the Radiology Department's Annual Report

Answer: (B)

When a unit lacks built-in exposure settings, a technique chart serves as the guide for selecting the right exposure factors (kVp, mA, time) to get diagnostic images with minimal radiation. The chart must be immediately accessible where the operator makes those exposure decisions, which is at the control panel. Posting it at each control panel ensures the correct chart is right where you’re adjusting settings, promoting consistency and reducing the chance of using improper exposure or needing repeats.

Posting it in the waiting room, in device storage, or only in an annual report doesn’t provide timely, direct access to the person taking the x-ray, so those locations aren’t appropriate.
