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.
ACTUAL 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.

2. A radiograph is defined as
a. a beam of energy that has the power to penetrate substances and record image
shadows on a receptor.
b. a picture on film produced by the passage of x-rays through an object or body.
c. the art and science of making radiographs by the exposure of an image receptor
to x-rays.
d. a form of energy carried by waves or a stream of particles.
ACTUAL 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

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.
ACTUAL 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.

a. Heinrich Geissler
b. Wilhelm Roentgen
c. Johann Hittorf
d. William Crookes
ACTUAL 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.
