QuestionAnswer
Concept of radiation protection that states that all exposures should be kept “as low as reasonably achievable.”
The positive electrode in the x-ray tube. The basic unit of matter.
“Braking radiation.” The sudden deceleration of electrons as they interact with highly positively charged nuclei.
The negative electrode in the x-ray tube.
X-rays at the center of the beam.
Differences in degrees of blackness on an image.
The portion of the x-ray unit that contains the master switch, the indicator light, the selector buttons, and the exposure button.
The overall darkness or blackness of an image.
The process of recording images of the teeth and adjacent structures by exposure to x-radiation.
A filmless method of capturing an image and displaying it by using an image receptor, an electronic signal, and a computer to process and store the image. Distortion Change in the
Change in the size of an image caused by incorrect vertical angulation.
The amount of energy absorbed by tissues.
A device used to detect and measure an accumulated dosage of radiation.
A negatively charged particle in the atom.
The ability to do work.
Flexible arm that is attached to the x-ray tubehead.
Effects of radiation that are passed on to future generations through genetic cells.
Film-based or digitally produced recordings of anatomic structures.
A recording medium for an image, normally film, phosphor storage plate (PSP), or a digital sensor.
The total energy of the x-ray beam.
An electrically charged particle.
Process by which electrons are removed from atoms, causing the harmful effects of radiation in humans.
Radiation that produces ionization, resulting in harmful effects.
Highest voltage of x-ray tube used during an exposure.
Time between exposure to ionizing radiation and appearance of symptoms.
Device used to protect the reproductive and blood-forming tissues from scatter radiation.
The proportional enlargement of an image.
Components of control panel.
Anything that occupies space and has form or shape.
One one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current.
The blurred or indistinct area that surrounds an image.
A device that measures exposure of personnel to ionizing radiation by measuring the intensity of visible light emitted from a crystal in the detector when heated. The intensity of light emitted is dependent upon the radiation exposure.
A minute (tiny) bundle of pure energy that has no weight or mass.
The most penetrating beam produced at the target of the anode.
Same as primary beam.
The mean energy or penetrating ability of the x-ray beam.
The number of x-rays produced in the dental unit; the quantity of x-rays produced is controlled by milliamperage.
Forms of waves of energy emission through space or material.
Image produced on photosensitive film by exposing the film to radiation and then processing it.
The science or study of radiation as used in medicine.
A form of secondary radiation that occurs when an x-ray beam has been deflected from its path by interaction with matter.
X-radiation that is created when the primary beam interacts with matter.
A solid-state image receptor that contains a silicon chip with an electric circuit.
A measure of how well an image reproduces the fine details or outline of an object.
Effects of radiation that cause illness and are responsible for poor health (such as cancer, leukemia, and cataracts) but are not passed on to offspring.
A flexible lead shield that is placed securely around the neck.
The part of the x-ray unit that contains the x-ray tube, the high￾voltage and low-voltage transformers, and insulating oil.
A focal spot in the anode.
High-energy ionizing electromagnetic radiation.
Automatic processor Machine that automates all film processing steps.
Assists in the positioning of the position indicator device (PID).
Image view that shows the crowns of both arches on one film.
