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.
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.

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.
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.

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.

d. Many dental diseases are typically discovered only through the use of dental
images.
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 component of comprehensive patient care. Many dental diseases are typically
discovered only through the use of dental images.

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

a. Otto Walkoff
b. Wilhelm Roentgen
c. Edmund Kells
d. Weston Price
ANSWER: C
Otto Walkoff was a German dentist who made the first dental radiograph. Wilhelm Roentgen
was a Bavarian physicist who discovered the x-ray. Edmund Kells exposed the first dental
radiograph in the United States using a live person. Price introduced the bisecting technique
