RADIOGRAPHY EXAM #1 (CHAPTERS 1-6) UPDATED
ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
radiation
Answer:
form of energy carried by waves/streams of particles
Question:
x-radiation
Answer:
high energy radiation produced by the collision of a beam of electrons with a
metal target in an x-ray tube
Question:
x-ray
Answer:
beam of energy that has the power to penetrate sub-stances and record image
shadows on film/sensors
Question:
radiography
Answer:
art and science of making radiographs
Question:
- identify underlying conditions - they provide more information than what
can be visualized clinically
Answer:
Importance/Uses of dental radiographs
Question:
William Conrad Roentgen
Answer:
Who discovered the x-ray?
Question:
November 8, 1895
Answer:
When was the x-ray discovered?
Question:
C. Edmund Kells

, Question:
matter
Answer:
anything that occupies space and has mass
Question:
atom
Answer:
fundamental unit of matter
Question:
ion
Answer:
atom that gains/loses an electron and becomes unstable (charged)
Question:
ionization
Answer:
production of ions
Question:
ion pair
Answer:
when an electron is removed from an atom during the ionization process -
reacts with ions until stable/neutral atoms are formed
Question:
particulate and electromagnetic
Answer:
2 types of ionizing radiation
Question:
particulate radiation
Answer:
- tiny particles of matter - have mass - travel in fast, straight lines - used in
cancer therapies
Question:
electromagnetic radiation
Answer:
- no mass - wave-like energy - used in diagnostics
Question:
wave concept and particle concept
Answer:
2 concepts of electromagnetic radiation
Question:
wave concept
Answer:
- waves - focus on velocity, wavelength, and frequency
