film speed

the relative sensitivity of film emulsion to light or radiation exposure; speed is inversely related to detail resolution.

film speed

The sensitivity of a photographic medium (e.g., a radiograph) to light or radiation. The film speed is determined by: the size of its silver halide crystals; the thickness of the emulsion; and the presence of radiosensitive dyes. Films are described as “fast” if the film requires little radiation to produce an image and “slow” if more radiation is needed.
