Consider an exposure that results in a receptor exposure of 0.001 microgray. The resulting image is expected to display which artifact?

Explanation:
When receptor exposure is extremely low, too few photons reach the detector to form a stable signal. The photon arrivals vary randomly, creating a grainy, mottled appearance known as quantum mottle (quantum noise). An exposure as low as 0.001 microgray leaves the image dominated by this random noise, so you’d expect a mottled look. Saturation would come from too much exposure, geometric distortion arises from misalignment or geometry issues, and excessive contrast isn’t the hallmark artifact of underexposure.
