Complete Solutions
Graded A+
Denning [Date] [Course title]
, Focusing Cup - Correct Answer: Directs electrons toward target
Thermionic Emission - Correct Answer: Filament electrons are boiled off producing an electron cloud
Bremsstrahlung - Correct Answer: AKA Breaking Radiation. Occurs when a high speed electron from the
cathode is deflected by the nucleus of a target atom
Characteristic Radiation - Correct Answer: Occurs when cathode electrons dislodge inner orbit electrons
from the target atoms.
Anode Heel Affect - Correct Answer: Reduction of beam intensity due to interaction with heel of target
Quality - Correct Answer: Refers to penetrating power of the beam
Quantity - Correct Answer: Refers to the number of xray photons in the useful beam
Primary Beam - Correct Answer: Beam exiting the tube before it gets to the patient
Remnant Radiation - Correct Answer: Photons that are exiting patient before getting to the IR
Inverse Square Law - Correct Answer: Intensity is inversely proportional to the square of the distance
Attenuation - Correct Answer: Absorption of the beam by the patient
Compton Effect - Correct Answer: Incident xray interacts with outer shell electron and ionizes the atom
Compton Effect - Correct Answer: What is the single most contribution to occupational exposure?
Photoelectric Absorption - Correct Answer: Incident xray is totally absorbed during the exposure, K shell
electron is ejected.
