    OOPS I found an error at Error at 9:31 ! Photoelectric Energy Range is not 10keV to 150keV the minimum can be as low as 0.3keV. Guess the proper energy range is from the k-shell binding energy of a low atomic number atom up to 150keV.
    The minimum energy for a photoelectric effect is the binding energy of the k-shell electron and for low atomic number atoms, such as those found in soft tissue, the binding energy of even K-shell electrons is low (e.g., 0.3 keV for carbon).

    The Photoelectric effect occurs at photon energies way below that required for Compton scattering. So your list at 0:29 should swap Photoelectric and Compton to be in the correct order of energies. Excellent presentation overall!

    Scatter Outta Compton?

  • @ajithkumarbs7640
    @ajithkumarbs7640 2 года назад

    It was an excellent presentation. I have a doubt on the occurrence of multiple scattering takes place at the Compton scattering.
    How does the multiple scattering on Compton finally leads to photoelectric effect ? Coz as the multiple scattering takes place the wavelength of the X-rays will be keep on reducing r8, then how comes the photoelectric absorption can occur with the energy less then that of required for compton scattering.? Kindly clarify me ! Thanks in advance.

    • @bobgrossman1

      These interactions are occurring in the body which means the atom that will photoelectrically absorb the x-ray photon might be atoms of Calcium or Oxygen or Carbon. These atoms have rather low K Shell binding energy levels. So a 60 kEv x-ray photon might exit the tube and enter the patient and have several Compton Scattering interactions, each reducing the energy of the x-ray photon and then eventually get photoelectrically absorbed by a Calcium atom. Hope that clarifies.

    What happens after with an electric photon ?? Is it possible to produce bremsstrahlung inside the human body through this interaction ??
