RAD Flashcards
Radiation
A form of energy carried by waves or a stream of particles
X-radiation
A high-energy radiation produced by the collision of a beam of electrons with a metal target in an X-ray tube.
X-ray
A beam of energy that has the power to penetrate substances and record image shadows on photographic film or digital sensors.
Radiology
The science or study of radiation as used in medicine; a branch of medical science that deals with the use of X-rays, radioactive substances, and other forms of radiant energy in the diagnosis and treatment of disease.
Radiograph
A two-dimensional representation of a three-dimensional object.
NOT X-RAY
Dental radiograph
A photographic image produced on an image receptor by the passage of X-rays through teeth and related structures.
Radiography
The art and science of making radiographs by the exposure of film to X-rays.
Ion
An atom that gains or loses an electron and becomes electrically unbalanced
Ionization
The production of ions, or the process of converting an atom into ions.
Radioactivity
The process by which certain unstable atoms or elements undergo spontaneous disintegration, or decay, in an effort to attain a more balanced nuclear state.
In dentistry, radiation (specifically x-radiation) is used, not radioactivity.
Ionizing radiation
Radiation that is capable of producing ions by removing or adding and electron to an atom.
Two groups:
Particulate radiation
Electromagnetic radiation
Particulate radiation
Tiny particles of matter that possess mass and travel in straight lines and at high speeds.
Beta particles
Alpha particles
