2. Which of the following is a form of radiation that is capable of creating electrically charged particles
by removing orbital electrons from the atom of normal matter through which it passes?
a. Ionizing radiation
b. Nonionizing radiation
c. Subatomic radiation
d. Ultrasonic radiation
CORRECT ANSWER: A
3. Regarding exposure to ionizing radiation, patients who are educated to understand the medical benefit
of an imaging procedure are more likely to
a. assume a small chance of biologic damage but not suppress any radiation phobia they may have.
b. cancel their scheduled procedure because they are not willing to assume a small chance of biologic
damage.
c. suppress any radiation phobia but not risk a small chance of possible biologic damage.
d. suppress any radiation phobia and be willing to assume a small chance of possible biologic damage.
CORRECT ANSWER: D

, 5. The advantages of the BERT method are
1. BERT does not imply radiation risk; it is simply a means for comparison.
2. BERT emphasizes that radiation is an innate part of the environment.
3. BERT provides an answer that is easy for the patient to comprehend.
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. All the options
CORRECT ANSWER: D
6. If a patient asks a radiographer a question about how much radiation he or she will receive from a
specific x-ray procedure, the radiographer can
a. respond by using an estimation based on the comparison of radiation received from the x-ray to natural
background radiation received.
b. avoid the patient’s question by changing the subject.
c. tell the patient that it is unethical to discuss such concerns.
d. refuse to answer the question and recommend that he or she speak with the referring physician.
CORRECT ANSWER: A
7. Why should the selection of technical exposure factors for all medical imaging procedures always
follow ALARA?
a. So that referring physicians ordering imaging procedures do not have to accept responsibility for
patient radiation safety.
b. So that radiographers and radiologists do not have to accept responsibility for patient radiation safety.
c. Because radiation- induced cancer does not appear to have a fixed threshold, that is, a dose level below
which a person would have no chance of developing this disease.
M
d. Because radiation- induced cancer does have a dose level at which individuals would have a chance of
developing this disease.
