Preparing for the Radiography Certification exam? This exam contains 200 multiple choice questions targeted to the 2023 ARRT Radiography Blueprint. Test your knowledge and see where your problem areas lie with two free radiography board exam questions taken from the BoardVitals Radiography question bank.
Question 1
High-velocity electrons (e-) that completely avoid the orbital electrons as they pass through a tungsten atom, yet come close enough to the nucleus of the atom to come under the influence of its positively charged electric field (P+), will produce what type of X-rays?
Answer Choices
- A.) Characteristic x-rays
- B.) Compton X-rays
- C.) Bremsstrahlung X-rays
- D. ) Thompson X-rays
Correct Answer
(C) Bremsstrahlung X-rays
Explanation
Bremsstrahlung literally means “braking.” When a high-velocity electron passes through a tungsten atom, avoiding the electrons, yet coming close enough to the nucleus to be affected by the positively charged electric field of the nucleus, the change of direction, or braking, causes a release of x-rays known as Bremsstrahlung.

Question 2
What is the relationship of LET and biological damage?
Answer Choices
- A.) They increase in direct proportion.
- B.) They are inversely proportional.
- C.) There is no relationship.
- D.) There is a nonlinear nonthreshold relationship.
Correct Answer
(A) They increase in direct proportion.
Explanation
The LET refers to the linear energy transfer, the amount of energy transferred by ionizing radiation per unit length of tissue traveled. LET is variable between radiation types. High-ionization radiation, including neutrons and alpha particles, cause more biological damage than radiation with a lower LET, including x-rays and gamma rays.

Question 3
Which skull position is most useful to demonstrate the sphenoid sinuses?
Answer Choices
- A.) AP axial
- B.) Lateral
- C.) Parietoacanthal
- D.) Caldwell
- E.) Submentovertical
Correct Answer
(E) Submentovertical
Explanation
The submentovertical projection is used to demonstrate the cranial base for the basal foramina, the bony portion of the Eustachian tubes, and the sphenoid sinuses. The study is performed with the patient’s head resting on the vertex. The CR is perpendicular to the IOML. The AP axial and PA axial or Caldwell view is used to demonstrate the occipital region of the skull and can be used to evaluate the sellar region. The parietoacanthal projection demonstrates the facial bones. The lateral projection is part of the routine skull series.
