What is the main difference between the photoelectric effect and characteristic radiation in the x-ray tube?
What is the main difference between the photoelectric effect and characteristic radiation in the x-ray tube?
- The photoelectric effect does not involve the creation of characteristic radiation, while it does in the x-ray tube.
- Characteristic radiation is produced in the body, while the photoelectric effect is produced in the x-ray tube.
- The incoming energy in the photoelectric effect is an electron interacting with the tungsten anode, while in characteristic radiation it is an x-ray photon interacting with an atom in the body.
- The incoming energy in the photoelectric effect is an x-ray photon interacting with an atom in the body, while in characteristic radiation it is an electron interacting with the tungsten anode. (correct)
What is a characteristic photon?
What is a characteristic photon?
- A photon that is emitted by a nucleus after a pair production.
- A photon that is produced in the x-ray tube.
- A photon that is emitted by an outer shell electron after a photoelectric interaction. (correct)
- A photon that is emitted by an inner orbital electron after a Compton interaction.
Why are photoelectric interactions less prevalent in the diagnostic energy range?
Why are photoelectric interactions less prevalent in the diagnostic energy range?
- Because the kVp level is too high in the diagnostic energy range.
- Because the likelihood of a Compton interaction is higher in the diagnostic energy range. (correct)
- Because the electron-binding energy of the atom in which the interaction occurs is too low in the diagnostic energy range.
- Because the likelihood of a pair production is higher in the diagnostic energy range.
