Rationales – Chapters 1–40
Chapter 1: Essential Concepts of Radiologic Science (25 Questions)
1. Matter is measured in:
a. kilograms
b. joules
c. electron volts
d. rems
Answer: a
Rationale: Matter is measured in kilograms (kg). Joules and electron volts measure energy,
while rems measure radiation dose equivalent.
2. Atoms and molecules are the fundamental building blocks of:
a. energy
b. radiation
c. matter
d. gravity
Answer: c
Rationale: Atoms and molecules are the fundamental building blocks of matter.
3. Ice and steam are examples of two forms of:
a. matter
b. radiation
c. energy
d. work
,Answer: a
Rationale: Ice (solid) and steam (gas) are examples of two forms (states) of matter.
4. The formula E = mc² is the basis for the theory that led to the development of:
a. x-rays
b. electromagnetic radiation
c. nuclear power
d. cathode ray tubes
Answer: c
Rationale: The formula E = mc² is the basis for the theory that led to the development of nuclear
power.
5. Radio waves, light, and x-rays are all examples of _____ energy.
a. nuclear
b. thermal
c. electrical
d. electromagnetic
Answer: d
Rationale: Electromagnetic energy includes radio waves, light, and x-rays as well as other parts
of the spectrum.
6. A moving object has _____ energy.
a. potential
b. kinetic
c. nuclear
d. electromagnetic
Answer: b
Rationale: A moving object has kinetic energy—the energy of motion.
, 7. What is the removal of an electron from an atom called?
a. Ionization
b. Pair production
c. Irradiation
d. Electricity
Answer: a
Rationale: The removal of an electron from an atom is called ionization.
8. Ionizing radiation is capable of removing _____ from atoms as it passes through matter.
a. neutrons
b. protons
c. electrons
d. ions
Answer: c
Rationale: Ionizing radiation is capable of removing electrons from atoms as it passes through
matter.
9. The energy of x-rays is:
a. thermal
b. potential
c. kinetic
d. electromagnetic
Answer: d
Rationale: X-rays are a form of electromagnetic energy.
10. The biggest source of man-made ionizing radiation exposure to the public is:
a. atomic fallout
b. diagnostic x-rays
