What happens when an incoming electron collides with the K-shell electron of a tungsten atom?
What happens when an incoming electron collides with the K-shell electron of a tungsten atom?
- Both the incoming electron and the K-shell electron are removed (correct)
- The K-shell electron is removed and the incoming electron is unaffected
- The incoming electron is removed and the K-shell electron is unaffected
- The K-shell electron is ejected and replaced by another electron from the same orbit
What are X-rays created by the interaction between an incoming electron and a K-shell electron called?
What are X-rays created by the interaction between an incoming electron and a K-shell electron called?
- Bremsstrahlung radiation
- Photoelectric effect
- Characteristic radiation (correct)
- Compton scattering
Why are no characteristic photons produced below 70 kVp?
Why are no characteristic photons produced below 70 kVp?
- The binding energy of a K-shell is 70 and it takes at least a 70-kVp exposure to eject this electron
- The binding energy of a K-shell is 70 and it takes at least a 69.5-kVp exposure to eject this electron
- The binding energy of a K-shell is 69.5 and it takes at least a 70-kVp exposure to eject this electron (correct)
- The binding energy of a K-shell is 69.5 and it takes at least a 69.5-kVp exposure to eject this electron
