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 imag
e shadows on a receptor.
c. a high-
energy radiation produced by the collision of a beam of electrons with a meta
l 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.

2. A radiograph is defined as
a. a beam of energy that has the power to penetrate substances and record imag

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 t
o 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 shado
ws 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.

a. An oral examination with dental images limits the practitioner to what is see
n 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 denta
l 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 imag
es are a necessary component of comprehensive patient care. Many dental diseases are typic
ally 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 th
e 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 resulte
d in a greenish fluorescence. William Crookes discovered in the late 1870s that cathode ray
s were streams of charged particles.

ray. Edmund Kells exposed the first dental radiograph in the United States using a live pers
