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. it 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. 1, 2, and 3
ANS: 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.
ANS: A

always follow ALARA? So that radiographers and radiologists do not have t
a. So that referring physicians ordering imaging procedures do not have to accept
responsibility for patient radiation safety.
b.
patient radiation safety.
c. Because radiation-induced cancer does not appear to have a dose level
below which individuals would have no chance of developing this disease.
d. Because radiation-induced cancer does have a dose level at which
individuals would have a chance of developing this disease.
ANS: C

, c. Radiation Safety Officer
d. Student radiologic technologist
ANS: C
10. Why is a question concerning the amount of radiation a patient will receive during a
specific x-ray procedure difficult to answer?
1. Because the received dose is specified in a number of different units of measure
