Chapter 01: Radiation History
MULTIPLE CHOICE
1. Radiation is defined as
a. a form of energy carried by waves or streams of particles.
b. a beam of energy that has the power to penetrate substances
and record image shadows on a receptor.
c. a high-energy radiation produced by the collision of a beam of
electrons with a metal target in an x-ray tube.
d. a branch of medicine that deals with the use of x-rays.
SELECTED CORRECT ANSWER: A
Radiation is a form of energy carried by waves or streams of particles.
An x-ray is a beam of energy that has the power to penetrate
substances and record image shadows on a receptor.
X-radiation is a high-energy radiation produced by the collision of a
beam of electrons with a metal target in an x-ray tube. Radiology is a
branch of medicine that deals with the use of
x-rays.

SELECTED CORRECT ANSWER: B
An x-ray is a beam of energy that has the power to penetrate
substances and record image shadows on a receptor. A radiograph is a
picture on film produced by the passage of x-rays through an object or
body. Radiography is the art and science of making dental images by
the exposure of a receptor to x-rays. Radiation is a form of energy
carried by waves or streams of particles.

3. Your patient asked you why dental images are important. Which
of the following is the correct response?
a. An oral examination with dental images limits the practitioner to
what is seen clinically.
b. All dental diseases and conditions produce clinical signs and
symptoms.
c. Dental images are not a necessary component of
comprehensive patient care.
d. Many dental diseases are typically discovered only through the
use of dental images.
SELECTED CORRECT ANSWER: D
An oral examination without dental images limits the practitioner to
what is seen clinically. Many dental diseases and conditions produce
no clinical signs and symptoms. Dental images are a necessary

a. Heinrich Geissler
b. Wilhelm Roentgen
c. Johann Hittorf
d. William Crookes
SELECTED CORRECT ANSWER: B
Heinrich Geissler built the first vacuum tube in 1838. Wilhelm
Roentgen discovered the
x-ray on November 8, 1895. Johann Hittorf observed in 1870 that
discharges emitted from the negative electrode of a vacuum tube
traveled in straight lines, produced heat, and resulted in a greenish
fluorescence. William Crookes discovered in the late 1870s that
cathode rays were streams of charged particles.
