Why should the selection of technical exposure factors for all medical imaging procedures
always follow ALARA?
So that referring physicians ordering imaging procedures do not have to accept responsibility
for patient radiation safety.
So that radiographers and radiologists do not have to accept responsibility for patient radiation
safety.

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
respond by using an estimation based on the comparison of radiation received from the x-ray
to natural background radiation received.

tell the patient that it is unethical to discuss such concerns.
refuse to answer the question and recommend that he or she speak with the referring
physician. - Answer✔respond by using an estimation based on the comparison of radiation
received from the x-ray to natural background radiation received.
