a. avoid the patient's question by changing the subject.
b. refuse to answer the question and recommend that he or she speak with the
referring physician.

d. respond by using an estimation based on the comparison of radiation received
from the x-ray to natural background radiation received.
- ANSWER d. respond by using an estimation based on the comparison of
radiation received from the x-ray to natural background radiation received.
2. 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. Because radiation-induced cancer does not appear to have a dose level below
which individuals would have no chance of developing this disease.
c. Because radiation-induced cancer does have a dose level at which individuals
would have a chance of developing this disease.

patient radiation safety.
