The energy level used during exposure that is measured in kilovolts is known as ...

• A. Kilovoltage.
• B. Milliampere.
• C. Latent period.
• D. Intensity.

Answer: (A)

Kilovoltage controls the energy of the X-ray photons in the beam—the beam’s penetrating power. Measured in kilovolts, this rating tells you how energetic the photons are: higher kilovoltage means more energy per photon, so the beam penetrates more readily and alters image contrast and exposure. The other terms refer to different concepts: milliampere is about the tube current and the number of photons produced, latent period is the time between exposure and development, and intensity is the overall brightness of the image, influenced by energy and current but not the specific energy level itself.
