ANS: D h
,2. Which of the following is a form of radiation that is capable of creating electrically
h h h h h h h h h h h h h h
chargedparticles by removing orbital electrons from the atom of normal matter through which
h h h h h h h h h h h h h h
it passes?
h h
a. Ionizing radiation h
b. Nonionizing radiation h
c. Subatomic radiation h
d. Ultrasonic radiation h
ANS: A h
3. Regarding exposure to ionizing radiation, patients who are educated to understand the
h h h h h h h h h h h
h medicalbenefit of an imaging procedure are more likely to
h h h h h h h h h
a. assume a small chance of biologic damage but not suppress any radiation
h h h h h h h h h h h
phobiathey may have.
h h h h
b. cancel their scheduled procedure because they are not willing to assume a
h h h h h h h h h h h
smallchance of biologic damage.
h h h h h
c. suppress any radiation phobia but not risk a small chance of possible
h h h h h h h h h h h h
biologicdamage.
h h
d. suppress any radiation phobia and be willing to assume a small chance of
h h h h h h h h h h h h
possiblebiologic damage.
h h h
ANS: D h
4. The millisievert (mSv) is equal to
h h h h h
a. 1/10 of a sievert. h h h
b. 1/100 of a sievert. h h h
c. 1/1000 of a sievert. h h h
d. 1/10,000 of a sievert. h h h
ANS: C h
5. The advantages of the BERT method are
h h h h h h
1. BERT does not imply radiation risk; it is simply a means for comparison.
h h h h h h h h h h h h
2. BERT emphasizes that radiation is an innate part of the environment.
h h h h h h h h h h
3. BERT provides an answer that is easy for the patient to comprehend.
h h h h h h h h h h h
a. 1 and 2 only h h h
b. 1 and 3 only h h h
c. 2 and 3 only h h h
d. All the options h h
ANS: D h
6. If a patient asks a radiographer a question about how much radiation he or she will
h h h h h h h h h h h h h h h
receivefrom a specific x-ray procedure, the radiographer can
h h h h h h h h h
a. respond by using an estimation based on the comparison of radiation received
h h h h h h h h h h h
fromthe x-ray to natural background radiation received.
h h h h h h h h
b. avoid the patient’s question by changing the subject.
h h h h h h h
c. tell the patient that it is unethical to discuss such concerns.
h h h h h h h h h h
d. refuse to answer the question and recommend that he or she speak with
h h h h h h h h h h h h
thereferring physician.
h h h
ANS: A h
7. Why should the selection of technical exposure factors for all medical imaging
h h h h h h h h h h h
hproceduresalways follow ALARA? h h h
a. So that referring physicians ordering imaging procedures do not have to
h h h h h h h h h h
acceptresponsibility for patient radiation safety.
h h h h h h
b. So that radiographers and radiologists do not have to accept responsibility for
h h h h h h h h h h h
, patient radiation safety. h h
c. Because radiation-induced cancer does not appear to have a fixed threshold, that
h h h h h h h h h h h h
is,a dose level below which a person would have no chance of developing this
h h h h h h h h h h h h h h h
disease.
h
d. Because radiation-induced cancer does have a dose level at which
h h h h h h h h h h
individualswould have a chance of developing this disease.
h h h h h h h h h
ANS: C h
8. The cardinal principles of radiation protection include which of the following?

d. Student radiologic technologist h h
ANS: C h
10. Why is a question concerning the amount of radiation a patient will receive during a
h h h h h h h h h h h h h h
specificx-ray procedure difficult to answer?
h h h h h h
1. Because the received dose is specified in a number of different units of measure.
h h h h h h h h h h h h h
2. Because the scientific units for radiation dose are normally not comprehensible by a
h h h h h h h h h h h h
patient.
h
3. Because the patient should not receive any information about radiation dose.
