shadows on a receptor.
c. a high-energ
̣ ỵ radiation produced by the collision of a beam of electrons with a
metal target

d. a branch of medicine that deals with the use of x-rays.
ANS: A
Radiation is a form of energỵ carried by waves or streams of particles. An x-ray is a beam of
energỵ that has the power to penetrate substances and record imagẹ shadows on a receptor. X-
radiation is a high-energ
̣ ỵ radiation produced by the collision of a beam of electrons with a
metal target
̣ in an x-ray tube. Radiologỵ is a branch of medicine that deals with the use of x-
rays.
