easy · MCQ · Q-908B7A
Which of the following interaction mechanisms in diagnostic radiology involves an incoming X-ray photon interacting with an inner-shell electron, resulting in the complete absorption of the photon and emission of a photoelectron?
- A.Coherent scattering
- B.Compton scattering
- C.Photoelectric effectCorrect answer
- D.Pair production
Solution
The photoelectric effect occurs when an incident X-ray photon interacts with an inner-shell (e.g., K or L shell) electron, transferring all of its energy to the electron, which is ejected as a photoelectron. The photon ceases to exist.
