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

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.
