3. Patients who have an understanding of the medical benefits of an imaging procedure
because they received factual information about the study before having the examination are
more likely to:
a. assume a small risk of biologic damage but not overcome any radiation phobia they may
have.
b. cancel their scheduled procedure because they are not willing to assume a small risk of
biologic damage.
c. overcome any radiation phobia but not assume a small risk of possible biologic damage.
d. overcome any radiation phobia and be willing to assume a small risk of possible biologic
damage.
ANS: D REF: 8
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.
ANS: C REF: 9
5. The advantages of the BERT method are:
1. it does not imply radiation risk; it is simply a means for comparison.
2. it emphasizes that radiation is an innate part of our environment.
3. the answer given in terms of BERT is easy for the patient to comprehend.

ANS: D REF: 9
6. If a patient asks a radiographer a question about the potential risk of radiation exposure
associated with a specific x-ray procedure, the radiographer should:
a. use his or her intelligence and knowledge to answer the question honestly and provide a
suitable example that compares the amount of radiation received from the procedure in question
with natural background radiation received over a given period of time.
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.
ANS: A REF: 9
7. Which of the following is the intention behind the ALARA concept?

c. Radiation Safety Officer
d. Student radiologic technologist
ANS: C REF: 8
10. Why is a question about the amount of radiation a patient will receive during a specific x-
ray procedure difficult to answer?
1. Because the received dose is measured in a number of different units
2. Because scientific units for radiation dose are not comprehensible by the patient
3. Because the patient should not receive any information about radiation dose
a. 1 and 2 only
b. 1 and 3 only
