Bremsstrahlung X-Rays "Bremsstrahlung" means "braking radiation" and is retained from the original German to describe the radiation which is emitted when electrons are decelerated or "braked" when they are fired at a metal target. A strong nuclear electric field inhibits penetration of the electron into . Abstract. Another parameter is the radiation length, defined as the distance over which the incident electron’s energy is reduced by a factor of 1/e (0.37) due to radiation losses alone. This refers to the fact that the radiation in this case is created by charged particles that are free both before and after the deflection that caused the emission.
