Concept of radiation protection that states that all exposures should be kept “as low as reasonably achievable.”

Negative electrode in the x-ray tube.

Overall darkness or blackness of a radiograph

concave metal cup inside the cathode of the dental x-ray tube. it surrounds the tungsten filament.

Silver Halide crystals

absorb radiation during x-ray exposure and store energy emitted from the radiation

highest voltage of x-ray tube used during an exposure.

time between exposure to ionizing radiation and appearance of image.

one one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current.

same as primary beam. most penetrating beam produced at the target of the anode.

image refers to structures that are less dense and permits the x-ray beam to pass through causing the images to appear dark or black. examples cavities, openings in bone, like sinus, canal, or foramen.

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.

form of electromagnetic radiation with high energy and short wavelength.

he angle formed by the long axes of the teeth and the film/image receptor is bisected into two equal parts, and the x-ray beam is directed perpendicular to the bisecting line

radiographic error that appears as a clear (white) are on dental x-ray image.

insufficient (not enough) vertical angulation

Process by which electrons are removed from atoms, causing the harmful effects of radiation in humans.

images are structures that are dense and resist the passage of radiation causing the image to appear light or white depending on the density. examples include bone, amalgam fillings, implants, and, braces.

Cephalometric radiograph

extraoral x-ray of the skull and facial bones

Electronic snapshot taken by sensors and displayed on a monitor.

Focusing cup	concave metal cup inside the cathode of the dental x-ray tube. it surrounds the tungsten filament.
Silver Halide crystals	absorb radiation during x-ray exposure and store energy emitted from the radiation
Kilovoltage kvp	highest voltage of x-ray tube used during an exposure.
Latent period/image	time between exposure to ionizing radiation and appearance of image.
milliamperage	one one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current.
primary radiation	same as primary beam. most penetrating beam produced at the target of the anode.
Radiolucent	image refers to structures that are less dense and permits the x-ray beam to pass through causing the images to appear dark or black. examples cavities, openings in bone, like sinus, canal, or foramen.
scatter radiation	form of secondary radiation that occurs when an x-ray beam has been deflected from its path by interaction with matter.
secondary radiation	x-radiation that is created when the primary beam interacts with matter.
x-ray	form of electromagnetic radiation with high energy and short wavelength.
bisecting technique	he angle formed by the long axes of the teeth and the film/image receptor is bisected into two equal parts, and the x-ray beam is directed perpendicular to the bisecting line
cone-cutting	radiographic error that appears as a clear (white) are on dental x-ray image.
elongation	insufficient (not enough) vertical angulation
foreshortening	excessive vertical angulation
ionization	Process by which electrons are removed from atoms, causing the harmful effects of radiation in humans.
Radiopaque	images are structures that are dense and resist the passage of radiation causing the image to appear light or white depending on the density. examples include bone, amalgam fillings, implants, and, braces.
Cephalometric radiograph	extraoral x-ray of the skull and facial bones
