TEST BANK FOR Radiation Protection in Medical
Radiography 8th edition
Consequences of ionization in human cells include 1. creation of
unstable atoms.
2. production of free electrons.
3. creation of highly reactive free radicals capable of producing substances
poisonous to the cell.
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. - -
Correct Answer ✅ --1, 2, 3, 4, & 5
Which of the following is a form of radiation that is capable of creating electrically
charged particles by removing orbital electrons from the atom of normal matter
through which it
passes?
a. Ionizing radiation
b. Nonionizing radiation
pg. 1
,c. Subatomic radiation
d. Ultrasonic radiation - - Correct Answer ✅ --a. Ionizing Radiation
Regarding exposure to ionizing radiation, patients who are educated to understand
the medical benefit of an imaging procedure are more likely to...
a. assume a small chance of biologic damage but not suppress any radiation
phobia they may have.
b. cancel their scheduled procedure because they are not willing to assume a
small chance of biologic damage.
c. suppress any radiation phobia but not risk a small chance of possible
biologic
damage.
d. suppress any radiation phobia and be willing to assume a small chance of
possible
biologic damage. - - Correct Answer ✅ --D. Suppress any radiation phobia
and be willing to assume a small chance of possible biologic
damage.

,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. - - Correct Answer ✅ --C. 1/1000 of a sievert
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 - - Correct Answer ✅ --D. 1, 2, & 3
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
pg. 3
, 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. - - Correct Answer ✅ --A. Respond by using an
estimation based on the comparison of radiation
received.
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. So that radiographers and radiologists do not have to accept responsibility
for 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. - - Correct Answer
