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.
ANS: 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.

b. a picture on film produced by the passage
of x-rays through an object or body.

by the exposure of an image receptor to x-
rays.

stream of particles.
ANS: 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.

b. Wilhelm Roentgen
c. Johann Hittorf
d. William Crookes
ANS: 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.
