Question 7

A picture on a film produced by the passage of x-rays through an object or body is termed:
A) radiology.
B) an x-ray.
C) a radiograph.
D) fluorescence.

Accepted Answer

A radiograph is an image or picture produced on a receptor (radiation-sensitive film, phosphor plate, or digital sensor) by exposure to ionizing radiation; a two-dimensional representation of a three-dimensional object. Specifically, a dental radiograph is a photographic image produced on film by
the passage of x-rays through teeth and related structures.
