  • Filtration of x-ray photons

    The absorption of some longer-wavelength, low-energy x-ray photons by an absorbing medium placed in the path of the beam. Materials used for x-ray absorption include aluminum, copper, molybdenum, and zinc.

  • 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. In radiography, the term “speed” denotes the comparative degree of darkening produced on a film, taking into consideration…
