K-shell - correct answer ✔✔When the atomic number of an element increases, it will take more energy
to remove which electron from the atom?
K-shell - correct answer ✔✔What electron shell has the highest binding energy?
It is higher - correct answer ✔✔What happens to the total energy of the electron when the electron is
further from the nucleus?
Kinetic energy of the photoelectron - correct answer ✔✔What is the symbol Eke known as?
Characteristic photon - correct answer ✔✔What form of energy is released as the electron transfers
from an outer shell to an inner shell?
Secondary radiation - correct answer ✔✔What is another term used for a characteristic photon?

toward the source?
Negatron - correct answer ✔✔In pair production, what is the electron with a negative charge called?
Pair production - correct answer ✔✔When the energy of the x-ray photon is transformed to matter in
the form of two electrons this interaction is known as what?

factors of 70 kVp and 40 mAs?
109.37 - correct answer ✔✔What is the entrance skin exposure for a PA chest that measures 20 cm with
technical factors of 100 kVp and 15 mAs?
Chest - correct answer ✔✔Which of the following is NOT an example of an examination with a high
entrance skin exposure (ESE)?
Increases dose - correct answer ✔✔What happens to patient dose as kVp is decreased and mAs is
increased?
Decreases ESE - correct answer ✔✔What happens to entrance skin exposure (ESE) if the source image
distance (SID) and source object distance (SOD) are increased?
10 percent - correct answer ✔✔When the source object distance (SOD) and source image distance (SID)
are between 40 and 50 inches one study states that the entrance skin exposure (ESE) decreases by what
percentage?
50-100 - correct answer ✔✔How many chest x-rays would a patient have to have in one year to equal
the natural background radiation?
Radiographer - correct answer ✔✔Who has the principal responsibility to present the patient with
enough information to allow the patient to reach a decision regarding the examination?
5 millirads - correct answer ✔✔When a patient has one PA chest x-ray, what is the average tissue dose in
the thorax, in millirads?
Increases dose - correct answer ✔✔What happens to patient dose when a grid is used?
Increases transmission - correct answer ✔✔What happens to the transmission of photons when the kVp
is increased with no other change in the technical factors for an exposure?
