Which of the following is a form of a. Ionizing Radiation
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
The millisievert (mSv) is equal to C. 1/1000 of a sievert
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.
,Which of the following provides the C. Diagnostic Efficacy
basis for determining whether an
imaging procedure or practice is
justified?
a. ALARA concept
b. BERT method
c. Diagnostic efficacy
d. NEXT program
Which of the following radiation B. Effective Dose
quantities is intended to be the best
overall measure of the biologic
effects of ionizing radiation?
a. Exposure
b. Effective dose
c. Absorbed dose
d. There is no radiation quantity that
is intended to be the best overall
measure of the biologic effects of
ionizing radiation.
,Which of the following statements A. It appears that no safe dose level exists for
below is true? radiation-induced malignant disease.
a. It appears that no safe dose level
exists for radiation-induced
malignant disease.
b. The ALARA principle establishes a
dose level for radiation-induced
malignancy.
c. The BERT method establishes a
dose level for radiation-induced
malignancy.
d. The NEXT program and reference
values establish a dose level for
radiation-induced malignancy.
Electromagnetic radiation travels or C
propagates through space in the
form of a wave but can interact with
matter as a particle of energy called
a photon. This dual nature is referred
to as
a. wave attenuation capability.
b. wave-particle interchange ability.
c. wave-particle duality.
d. wave-particle phenomena.
, Which of the following statements A
concerning the 1979 nuclear reactor
accident at TMI-2 is not true?
a. Many excess cancer deaths have
been predicted to occur in the 2
million people living within 50 miles
of the plant at the time of the
accident.
b. During the time of the accident, if
persons living within a 100-mile
radius of the nuclear power plant
received an average radiation
exposure of 15 microgray, and this
dose is used as the population dose,
then no more than two additional
resulting cancer deaths can be
predicted in the exposed inhabitants
as a consequence of radiation
exposure.
c. The average dose received by the
exposed population living within a
50-mile radius of the TMI nuclear
power station at the time of the
accident was determined to be 0.08
mSv, which is well below the average
annual background level.
d. No melt-through of the reactor
vessel resulted during the accident.
