A lateral L-5/S-1 lumbosacral junction is performed with the central ray (CR) directed 2
inches anterior to the anterior superior iliac spine (ASIS) and 1-1/2 inches inferior to the
iliac crest. Which statement describes this method?
A. The central ray will be well posterior to the L-5/S-1 junction.
B. The central ray will be well anterior to the L-5/S-1 junction.
C. The central ray will be correctly centered to the L-5/S-1 junction.
D.The central ray will be well superior to the L-5/S-1 junction.
B
What is the best projection and position to demonstrate the right cervical intervertebral
foramina?
A. Cross table lateral projection, dorsal recumbent position
B. Cross table lateral projection, ventral recumbent position.
C. Anteroposterior (AP) axial oblique projection, left posterior oblique (LPO) position
D. Anteroposterior (AP) axial oblique projection, right posterior oblique (RPO) position.

,In a typical x-ray examination room, what is considered a secondary protective barrier?
A. Wall below the chest board
B. Ceiling
C. Wall behind chest board
D. Floor
B
The Z number of oxygen is 8. The elemental oxygen atom has two electron shells. How
many electrons occupy an electrically neutral oxygen atom's outer shell?
A. 4
B. 6
C. 8
D. 2
B
What type of relationship does cell growth rate have on the sensitivity of tissues to ionizing
radiation?
A. Disproportional
B. Inverse
C. Direct
D. Not related
C
How much can exposure to the lens of the eyes be reduced by utilizing the posteroanterior
(PA) projection of the cranium over the anteroposterior (AP) projection?
A. 30%
2|Page
,B. 55%
C. 95%
D. 75%
C
What characteristics do high linear energy transfer (LET) radiations have when compared
with low-LET radiation?
A. Decreased mass, increased penetration
B. Electrically charged, less ionizing.
C. Increased mass, decreased penetration.
D. No electrical charge, more ionizing.
C
Which statements are accurate about control monitoring badges? (Select the two that
apply.)
A. Returned to the supplier in a special envelope separate from individual badges.
B. Should be kept in a distant room from the radiation area.
C. Measures background exposure during transportation, handling, and storage.
D. Should be worn underneath the lead apron during fluoroscopy exams.
E. Measures radiation exposure in the work area.
C. Measures background exposure during transportation, handling, and storage.
E. Measures radiation exposure in the work area.
Which term describes stray radiation that is emitted through the x-ray tube housing?
A. Off-focus
B. Leakage

, C. Scatter
D. Exit
B
Which items can be used as indicators of the quality of the diagnostic x-ray beam? (Select
the two that apply.)
A. Object to image receptor distance (OID).
B. Half Value Layer (HVL).
C. Source to image receptor distance (SID).
D. Kilovolts peak (kVp).
E. S (exposure time).
B. Half Value Layer (HVL).
D. Kilovolts peak (kVp).
kVp is our x-ray beam quality controller, which is also indicated by HVL
measurements. Exposure time affects beam quantity, not quality. OID and SID affect
quantity, but not quality.
When the frequency of the voltage waveform supplied to the x-ray tube is increased, what
aspect is reduced? (Select the three that apply.)
A. Patient exposure.
B. Average wavelength of the x-ray beam.
C. Power consumption.
D. Heat loading on the anode disk.
E. X-ray output of the tube.
A. Patient exposure.
B. Average wavelength of the x-ray beam
D. Heat loading on the anode disk.
