Chapter 01: Radiation History 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. ANS: 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.
