Radiation is a form of energy carried by waves or streams of particles. An x-ray is a beam of energy th
substances and record image shadows on a receptor. X-radiation is a high-energy radiation produced by
electrons with a metal target in an x-ray tube. Radiology is a branch of medicine that deals with the use

a. a beam of energy that has the power to penetrate substances and record image
shadows on a receptor.
b. a picture on film produced by the passage of x-rays through an object or body.

An x-ray is a beam of energy that has the power to penetrate substances and record image shadows on
picture on film produced by the passage of x-rays through an object or body. Radiography is the art and
images by the exposure of a receptor to x-rays. Radiation is a form of energy carried by waves or strea

a. An oral examination with dental images limits the practitioner to what is seen
clinically.
b. All dental diseases and conditions produce clinical signs and symptoms.
c. Dental images are not a necessary component of comprehensive patient care.
