The process of removing or adding an orbital electron to an atom is:
Ionization
The reduction in the number of x-ray photons in the beam, and the subsequent loss of energy, as the beam passes through matter”, is the definition of what?
Attenuation
Electrons have what charge?
Negative
The energy shell closest to the nucleus is labeled the _____ shell.
K
A technologist's primary source of occupational exposure is __________________.
Scatter
What interaction with matter occurs when an extremely high energy incident photon impacts the nucleus, causing it to emit a nuclear fragment?
Photodisintegration
Which component of the collimator serves as about 1mm Al/Eq of filtration?
Mirror
The amount of force required to remove an electron from orbit is referred to as what?
Binding energy
The process of electrons transferring from outer shells to inner shells is called _______________.
Characteristic cascade
Patient dose is greatest in which interaction?
Photoelectric absorption
What interaction with matter occurs when a very low energy incident photon interacts with the electron(s) of an atom causing it to vibrate, and then releasing energy in the form of a secondary photon with the exact same energy as the incident photon?
Coherent scattering
During Compton scattering, the scattered photon will ________________.
Which of the five interactions with matter are relevant at diagnostic levels? 2
Which part of the collimator serves to reduce penumbral blur?
Lower shutters
Increased kVp has what effect on the production of scatter? (increase, decrease, none)
Increases it
During photoelectric absorption, what happens to the incident photon?
It impacts a tightly bound electron and is completely absorbed
Explain PBL
Positive Beam Limitation (PBL) is an automatic collimation system on radiographic equipment that electronically uses the collimator shutters automatically adjust to match the receptor size, thereby minimizing unnecessary patient exposure.
What interaction with matter occurs when an incident photon interacts with a tightly bound inner shell electron?
Photoelectric absorption
Which beam restricting device is a piece of metal with a hole in it, attached to the port?
Aperture diaphragm
Explain why does tight collimation effect on image receptor exposure?
Decreases scatter production
Write the formula represents the inverse square law?
I 1/I 2= (D2/D1)2
The amount of filtration can be expressed in which of the following ________?
Al/Eq
HVL
For photoelectric absorption to occur, the incident photon energy must be ____________.
At least slightly higher than the electron binding energy
During the Compton effect, what probably going to happens to the recoil electron?
it will be captured by a nearby ionized atom
The energy of a characteristic photon is ____.
the difference between the binding energy of the outer and inner shells between which the electron dropped.
