BREMSSTRAHLUNG RADIATION

Physics

BREMSSTRAHLUNG RADIATION

1. If an incoming electron penetrates the K-shell and approaches the nucleus, it is deflected.
2. During the deflection, the electron slows down and emits an X-ray photon.
3. Except in mammography, 80% of X-rays emitted from an X-ray tube are bremsstrahlung (breaking radiation).
4. Most electrons will first lose some energy as heat before interacting with the nucleus.
5. Bremsstrahlung radiation is a continuous spectrum.
6. The maximum photon energy (in keV) is numerically equal to the kV.
