1. Consequences \ of \ionization \ in \human \ cells \ include
1. creation \ of \unstable \ atoms.
2. production \ of \free \ electrons.
3. creation \of \highly \ reactive \ free \molecules \ (called \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.
6. production \ of \low-energy \ x-ray \photons.

b. 2, \3, \4, \and \ 5 \only
c. 3, \4, \5, \and \ 6 \only
d. All \the \options
ANS: \ D
,2. 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
c. Subatomic \ radiation
d. Ultrasonic \ radiation
ANS: \ A
3. 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.
ANS: \ D
4. 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.
ANS: \ C
5. The \advantages \ of \the \BERT \ method \ are
1. BERT \does \not \imply \ radiation \ risk; \it \is \simply \ a \means \ for \comparison.
2. BERT \emphasizes \ that \radiation \ is \an \innate \ part \of \the \environment.
3. BERT \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. All \the \options
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
7. 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 \fixed \ threshold, \ that
\is, \a \dose \level \ below \which \ a \person \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
8. The \cardinal \ principles \ of \radiation \ protection \ include \ which \ of \the \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 \ by \the
\hospital \administration \ with \ being \ directly \ responsible \ for \the \ execution, \ enforcement,
\ and \maintenance \ of \the \ ALARA \program?
a. Assistant \ administrator \ of \the \facility
b. Chief \of \staff
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.
2. Because \the \scientific \ units \ for \radiation \ dose \are \normally \ not \comprehensible \ by \a
\patient.
3. Because \the \patient \ should \ not \receive \ any \information \ about \radiation \ dose.
a. 1 \and \2 \only
b. 1 \and \3 \only
c. 2 \and \3 \only
d. All \the \options
ANS: \A

a. Environmental
b. Ionizing
c. Internal
d. Nonionizing
ANS: \B
