The significance of the Compton effect is it becomes the dominant process when human tissues are irradiated in the 30 keV to 30 MeV energy range which is the diagnostic and therapeutic radiation range. 6 x 10 23 ), thus the Compton effect is independent of the atomic number (Z) of the absorber. An exception though is the element hydrogen, which has no neutrons in its nucleus and therefore has an electron density which is twice that of all other elements (approx.

Photon energy 1 relatively constant over the range 10-600keV.Ītomic number (unlike photoelectric effect and pair production) Number of outer shell electrons, i.e. the electron density Thus, the energy of the scattered photon decreases with increasing scattered photon angle. The wavelength change of the scattered photon can be determined by 0.024 (1- cos θ), where θ is scattered photon angle. Energy and momentum are conserved in this process. The Compton effect is a partial absorption process and as the original photon has lost energy, known as Compton shift (i.e. ![]() The scattered photon will have a different wavelength (observed phenomenon) and thus a different energy (E=hc/λ). ![]() It occurs due to the interaction of the photon (x-ray or gamma) with free electrons (unattached to atoms) or loosely bound valence shell (outer shell) electrons. The resultant incident photon is scattered (changes direction) and imparts energy to the electron (recoil electron). It is the main cause of scattered radiation in a material. Compton effect or Compton scatter is one of principle forms of photon interaction.
