Graininess of a radiographic image results from

A) large silver halide crystals.
B) the addition of radiosensitive dyes.
C) a decrease in film speed.
D) film packets that contain two films.

A
Explanation: A) The larger crystals used in high-speed (fast) film result in a certain amount of graininess that reduces the sharpness of the radiographic image. It has been determined that this slight loss of image sharpness does not interfere with diagnosis and is tolerated because of the reduction in patient radiation exposure.
