[Ger. Bremsstrahlung, braking radiation]
bremsstrahlungGerman: braking radiation. A broad spectrum—rather than an energy peak of electromagnetic radiation resulting from the rapid deceleration of a charged particle—photon or electron when it hits the electron cloud of an atom’s nucleus.
braking radiation produced by the electrons being decelerated in the target of the x-ray tube. These rays of mixed wavelengths form the heterogeneous part of the x-ray beam.
