MULTIPLE CHOICE
1. Consequences of ionization in human cells include
1. creation of unstable atoms.
2. production of free electrons.
3. creation of highly reactive free molecules (called free radicals) capable of
gi
producing subs tances poisonous to the cell.
ig
4. creation of new biologic molecules detrimental to the living cell.
5. injury to the cell that may manifest itself as abnormal function or loss of function.
6. production of low-energy x-ray photons.
a. 1, 2, 3, and 4 only

ANSWER: D
2. Which of the following is a form of radiation that is capable of creating electrically
gi
charged p articles by removing orbital electrons from the atom of normal matter
ig gi gi
through which it passes?
a. Ionizing radiation
b. Nonionizing radiation
c. Subatomic radiation
d. Ultrasonic radiation
ANSWER: A
3. Regarding exposure to ionizing radiation, patients who are educated to understand
the medic al benefit of an imaging procedure are more likely to
gi
a. assume a small chance of biologic damage but not suppress any radiation
gi gi
phobia the y may have.
ig
b. cancel their scheduled procedure because they are not willing to
assume asma ll chance of biologic damage.
gi
c. suppress any radiation phobia but not risk a small chance of possible
biologi c damage. ig
d. suppress any radiation phobia and be willing to assume a small chance
gi
ofpossibl e biologic damage.ig
ANSWER: D
4. The millisievert (mSv) is equal to
a. 1/10 of a sievert.
b. 1/100 of a sievert.
c. 1/1000 of a sievert.
d. 1/10,000 of a sievert.
ANSWER: C
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. gi
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
gi gi
d. All the options
ANSWER: D
, 6. If a patient asks a radiographer a question about how much radiation he or she will
receive fro m a specific x-ray procedure, the radiographer can
ig
a. respond by using an estimation based on the comparison of radiation
received from the x-ray to natural background radiation received.
ig
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
gi
speak with t he referring physician. gi
ANSWER: A
7. Why should the selection of technical exposure factors for all medical imaging
procedu res always follow ALARA?
ig
a. So that referring physicians ordering imaging procedures do not have to
gi gi
accept r esponsibility for patient radiation safety.
gi
b. So that radiographers and radiologists do not have to accept responsibility for
gi
patient radiation safety.
c. Because radiation-
induced cancer does not appear to have a fixed threshold, that is, a
gi ig
dose level bel ow which a person would have no chance of developing this
disease.
d. Because radiation-
induced cancer does have a dose level at which individuals would have
gi ig
a c hance of developing this disease.
ANSWER: C
8. The cardinal principles of radiation protection include which of the following?
gi gi
a. Time
b. Distance
c. Shielding
d. All the options
ANSWER: D
9. In a hospital setting, which of the following professionals is expressly charged by the
hospit al administration with being directly responsible for the execution,
gi
enforcement, and mainten ance of the ALARA program?
a. Assistant administrator of the facility
b. Chief of staff
c. Radiation Safety Officer
d. Student radiologic technologist
ANSWER: C
10. Why is a question concerning the amount of radiation a patient will receive
during a specifi c x-ray procedure difficult to answer?
gi ig
1. Because the received dose is specified in a number of different units of measure.
2. Because the scientific units for radiation dose are normally not comprehensible
gi
by
a patien t.
gi
3. Because the patient should not receive any information about radiation dose.
a. 1 and 2 only gi
b. 1 and 3 only gi
c. 2 and 3 only
gi gi
d. All the options
ANSWER: A
11. X-rays are a form of which of the following kinds of radiation?
a. Environmental
b. Ionizing
