Hey! Let's make an x-ray.
Types of x-rays and radiation
100
Accelerated hydrogen nuclei, mass of 1, and charge of +1.
What is a proton?
100
When an atom loses an electron, the atom becomes more this.
What is positive.
100
In X-ray beam quality, this is the potential difference between two electrical charges.
What is voltage.
100
Electricity from the wall outlet supplies the power to generate x-rays. The current is directed to the filament circuit and ( ) in the tubehead.
What is step-down transformer?
100
In theory, this type of radiation has particles traveling as a wave through matter or space.
What is electromagnetic radiation?
200
These are the shells outside the nucleus. *Bonus* What is the binding energy and what it is measured in?
What is K, L, M, N, O. Electrostatic force measured in Volts or Kilo electron volts
200
The number of protons and neutrons in the nucleus will determine its atomic ( ), and atomic ( ).
What is number and weight?
200
Weightless bundles of energy without an electrical charge that travel in waves with a specific frequency at the speed of light.
What is x-rays?
200
The filament circuit uses ( ) to heat the tungsten filament in the cathode. Thermionic emission occurs, and the release of electrons.
What is 3 to 5 volts?
200
These are the four types of particulate radiation. Hint: think PANE.
What are electrons, alpha particles, protons, and neutrons?
300
The smallest amount of a substance that possesses its characteristic properties.
What is a molecule?
300
These are the two kinds of ionizing radiation.
What is particulate radiation, and electromagnetic radiation.
300
The speed of light.
What is 186,000 mi/sec?
300
The electrons stay in an electron cloud until the ( ) is activated. When the exposure button is pushed, the high-voltage circuit is activated.
What is high-voltage circuit?
300
These are emitted from the nuclei of heavy metals. Also they exist as two protons and neutrons, without electrons.
What is alpha particles?
400
The process by which certain unstable atoms or elements undergo spontaneous disintegration, or decay, in an effort to attain a more balanced nuclear state.
What is radioactivity?
400
The production of ions, or the process of converting an atom into ions.
What is ionizing?
400
Used to describe the penetrating power of an x-ray beam.
What is quality?
400
The molybdenum cup in the cathode directs electrons to the tungsten target in to anode. When electrons strike the tungsten target, less than ( ) of the energy is converted to x-rays, the remaining ( ) is lost as heat.
What is 1% and 99%?
400
The penetrating x-ray beam that is produced at the target of the anode.
What is primary radiation?
500
These are fast-moving electrons emitted from the nucleus of radioactive atoms. *BONUS* Give an example.
What is beta particles? Cathode rays.
500
This is the result when an electron is removed from an atom in the ionizing process.
What is an ion pair?
500
This concept states that photons travel as waves at the speed of light and move though space in a straight line.
What is particle concept?
500
A small number of x-rays are able to exit the x-ray tube through the ( ) portion of the tube. X-rays travel through the unleaded glass window, the tubehead seal, and aluminum disks. The size of the x-ray beam is restricted by the ( ). The x-ray beam exits the tubehead at the opening of the( ).
What is unleaded glass window, lead collimator, and PID?
500
Weightless bundles of energy, no electrical charge, and travel in waves with a specific frequency at the speed of light AND x-ray photons interact with the material they penatrate causing ionization.
What is x-radiation?
