Exposure indicators provide a numeric measure of detector exposure; consistent EI helps maintain uniform brightness.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Exposure indicators are numeric values that reflect how much radiation reaches the image receptor. They provide an objective measure of receptor exposure, helping technologists judge and adjust technique. When a consistent exposure index is used, images tend to have uniform brightness because the EI corresponds to a target level of receptor exposure. This standardization supports dose management and image quality, as deviations (too high or too low EI) signal overexposure or underexposure. The statement is true: exposure indicators measure detector exposure, and maintaining a consistent EI helps keep brightness uniform.
