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. ......ANSWER......B.
Effective Dose
Which of the following statements below is true?
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. ......ANSWER......A. It appears that no safe
dose level exists for radiation-induced malignant disease.
Electromagnetic radiation travels or 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.

Which of the following statements 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.
......ANSWER......A
Terrestrial radiation includes which of the following sources?
a. Long-lived radioactive elements such as uranium-238, radium-226,
and
thorium-232 that are present in variable quantities in the crust of the
earth
