Chapter 13 Flashcards
What is attenuation?
the reduction in the number of x-ray photons in the beam, and subsequent loss of energy, as the beam, passes through matter
What is attenuation the result of?
x-rays photons interacting with matter losing energy through these interactions
What are the five basic interactions between x-rays and matter?
Photoelectric absorption, coherent scattering, Compton scattering, pair production, and photodisintegration
When does photoelectric absorption result?
when an x-ray photon interacts with an inner-shell electron
When is a photoelectric interaction most likely to occur?
when the incident photon possess a slightly greater energy than the binding energy of the electrons in the inner shells.
What does the incident photon need to cause a photoelectric interaction?
an energy that is slightly greater than the binding energy of the electron for the interaction to occur.
When does photoelectric absorption result?
when an x-ray photon interacts with an inner-shell electron
When is photoelectric absorption interaction most likely to occur?
when the incident x-ray photon possess a slightly greater energy then the binding energy of the electrons in the inner shells
