MULTIPLE CHOICE
1. Consequences of ionization inhuman cells include
1. creation of unstable atoms.
jj
2. production offree electrons.
3. creation ofhighly reactive free molecules (calledfreeradicals) capable
jjj
of producing substances poisonous to the cell.
jj
4. creation ofnew biologic molecules detrimental to the living cell.
5. injury to the cell that may manifest itself asabnormal function or loss offunction.
6. production of low-energy x-ray photons.
a. 1,2, 3, and 4 only
b. 2,3, 4, and 5 only
c. 3,4, 5, and 6 only
d. All the options
ANS: D
,2. Which ofthe following is aform ofradiation that is capable ofcreating electrically
charged particles by removing orbital electrons from the atomofnormal matter
through which it passes?
a. Ionizing radiation
b. Nonionizing radiation
c. Subatomic radiation
d. Ultrasonic radiation
ANS: A
3. Regarding exposure toionizing radiation, patients who areeducated to understand the
medical benefit of animaging procedure are more likely to
a. assume asmall chance ofbiologic damage butnot suppress anyradiation
phobia they may have.
b. cancel their scheduled procedure because they arenot willing to assume a
small chance of biologic damage.
c. suppress anyradiation phobia but not risk asmall chance ofpossible
jjj
biologic damage.
d. suppress anyradiation phobia andbewilling to assume a small chance
ofpossible biologic damage.
j
ANS: D
4. The millisievert (mSv) isequal 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
5. The advantages of the BERT method are
1. BERT doesnot imply radiation risk; it is simply ameans forcomparison.
2. BERT emphasizes that radiation is aninnate partofthe environment.
j
3. BERT provides ananswerthat is easyfor the patient tocomprehend.
a. 1and 2 only
b. 1and 3 only
c. 2and 3 only
d. All the options
ANS: D
6. Ifapatient asksa radiographer aquestion about howmuch radiation he orshe will
receive from aspecific x-ray procedure, the radiographer can
a. respond byusing an estimation based on the comparison ofradiation received
jj jjj jjj
from the x-ray to natural background radiation received.
b. avoid thepatient’s question bychanging the subject.
c. tell the patient that it is unethical to discuss such concerns.
d. refuse toanswer thequestion andrecommend that heorshe speakw ith the
j
referring physician.
ANS: A
7. Whyshould the selection of technical exposure factors for allmedical imaging
procedures always follow ALARA?
a. So that referring physicians ordering imaging procedures donothave to
jjj
accept responsibility for patient radiation safety.
b. Sothat radiographers and radiologists donot have to accept responsibility for
j
, patient radiation safety.
c. Because radiation- i nduced cancer doesnot appearto have afixed threshold, that
jj
is, a doselevel below which aperson would have no chance of developing this
j
disease.
d. Because radiation- i nduced cancerdoeshave adoselevel at w hich individuals
jj jj
would have achance ofdeveloping this disease.
ANS: C
8. The cardinal principles ofr adiation protection include
j which ofthe following?
a. Time
b. Distance
c. Shielding
d. All the options
ANS: D
9. In a hospital setting, which of the following professionals is expressly charged bythe
jj jjj
hospital administration with being directly responsible for the execution, enforcement,
and maintenance of the ALARA program?
a. Assistant administrator of the facility
j
b. Chief of staff
c. Radiation Safety Officer
d. Student radiologic technologist
ANS: C
10. Whyis a question concerning theamount ofradiation apatient will receive during
j
aspecific x-ray procedure difficult to answer?
1. Because the received doseis specified in a number ofdifferent units ofmeasure.
jjj
2. Because the scientific units for radiation dosearenormally not comprehensible by
apatient.
3. Because the patient should not receive anyinformation about radiation dose.
a. 1and 2 only
b. 1and 3 only
c. 2and 3 only
d. All the options
ANS: A
11. X-raysareaform ofwhich ofthe following kinds ofradiation?
a. Environmental
b. Ionizing
c. Internal
d. Nonionizing
ANS: B
12. What unit is used to measure radiation exposure in the metric International System ofUnits?
a. Coulomb perkilogram
b. Milligray
c. Millisievert
d. Sievert
ANS: A
13. What organizationwas founded in 2007 that continues their pursuit to raise awareness of the
need for dose reductionprotocols bypromotingpediatric-specified scanprotocols to be used
for bothradiology and non-radiology users ofCT?
a. U.S. Foodand Drug Administration
