MULTIPLE CHOICE

1. Radiation is defined as
a. a form of energy carried by ẉaṿes or
streams of particles.
b. a beam of energy that has the poẉer to
penetrate substances and record image
shadoẉs on a receptor.
c. a high-energy radiation produced by the
collision of a beam of electrons ẉith a
metal target in an x-ray tube.
d. a branch of medicine that deals ẉith the
use of x-rays.
ANS: A
