How small can you go?
Occupies space and has mass
A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube
What is x-radiation?
I am a negative electrode that consists of a tungsten wire filament in a cup-shaped holder made of molybdenum. I supply electrons necessary to generate x-rays.
What is a cathode?
I surround the x-ray tube and transformers inside the tubehead. I prevent over heating by absorbing the heat created by the production of x-rays
What is insulating oil?
A form of secondary radiation and is the result of an x-ray that has been deflected from its path by the interaction with matter.
What is scatter radiation?
Fundamental unit of matter
What is an atom?
An image or picture produced on a receptor by exposure to ionizing radiation; a two dimensional representation of a three dimensional object
What is a radiograph?
In sheets of 0.5mm increments I help filter out long, low penetrating x-rays
I am responsible for the number of electrons passing through the cathode. If you adjust me you can increase or decrease the amount of electrons generated.
What is mA or milliamperage?
When an x-ray photon passes through matter without any interaction. Responsible for the densities on dental radiographs.
What is the ideal intensity beam?
An atom that gains or loses an electron and becomes electronically unbalanced
What is an ion?
The art and science of making radiographs by the exposure of film to x-rays
What is radiography?
I am the heart of the x-ray generating system
I dissipate heat away from the tungsten target.
What is the copper stem?
A type of scatter radiation where ionization takes place. This type of scatter accounts for 62 % of the scatter that occurs in radiography.
Whats is compton scatter?
Carries a positive electrical charge
What is a proton?
Any person who positions, exposes, and processes dental x-ray image receptors
What is a dental radiographer?
I decrease the voltage from the incoming 110 or 220 line voltage to the 3 to 5 volt use by the filament circuit
What is a step-down transformer?
The release of electrons from the tungsten filament when the electrical current passes through it and heats the filament.
What is thermionic emission?
The penetrating x-ray beam that is produced at the target of the anode and that exits the tubehead.
What is primary radiation?
Carries a negative electrical charge
What is an electron?
What is radiation?
I am a positive electrode, consisting of a wafer-thin tungsten plate embedded in a solid copper rod. I convert electrons into x-ray photons.
What is an anode?
Used to increase the voltage from the incoming 110 or 220 line voltage to the 65,000 to 100,000 volts used by the high-voltage circuit.
What is the step-up transformer?
A type of scatter that undergoes a change in direction without a change in energy. It is essentially "unmodified" and no ionization occurs. This type of scatter accounts for 8% of interactions in dental radiography.
What is Coherent scatter?
