|
Ionization |
The act of breaking an atom. If an atom gains an electron it will have negative charge. If an atom loses an electron it will have a positive charge |
|
|
Ion |
An unbalanced atom |
|
|
Electromagnetic radiation |
The propagation of wave-like energy without mass space or matter. Frequency and wavelength are inversely related |
|
|
The Binding energy or binding force of an electron is |
Determined by the distance between the orbiting electrons and the nucleus |
|
|
An ion pair results when |
An electron is removed from an atom |
|
|
Radiation |
The emission and propagation of energy through space or a substance in the form of waves or particles. |
|
|
Radioactivity |
The process by which certain unstable atoms or elements undergo spontaneous decay in an effort to obtain a more balanced nuclear state |
|
|
True or false: The orbiting show closest to the nucleus has the highest energy level |
True |
|
|
Photons |
A component of the particle concept of electromagnetic radiation |
|
|
Ionizing radiation |
Radiation capable of producing ions by either adding or removing an electron. May be classified as to whether it is particulate or electromagnetic radiation. |
|
|
Particulate radiation What is it? And what are the four kinds? |
Tiny particles of matter. Electrons, alpha particles, protons, neutrons. |
|
|
Electromagnetic radiation capable of ionization |
X-rays |
|
|
Control panel consist of 4 things. What are they |
On and off switch, indicator lights, control devices for kilovoltage and milliamperage, plug into electrical outlet |
|
|
The extension arm has three functions what are they |
Houses electrical wires Allows movement and positioning Suspends x-ray tube head |
|
|
Molecules |
Two or more atoms joined together by chemical bond |
|
|
Matter |
Anything that occupies space and has mass. When matter is altered, energy results |
|
|
Electrons |
Tiny negatively charged particles Maintained in orbit by electrostatic force |
|
|
Direct current |
When electrons flow in one direction through a conductor |
|
|
Alternating current |
When electrons flow in two opposite directions |
|
|
Rectification |
The conversion of alternating current into direct current |
|
|
Nucleus |
Made of protons and neutrons. |
|
|
Atom |
The fundamental unit of matter |
|
|
Electrical currents |
A flow of electrons through a conductor |
|
|
Amperage |
The measurement of the number of electrons moving through a conductor |
|
|
Voltage |
The measurement of electrical force that causes electrons to move from a negative Pole to a positive one |
|
Memorize |
. |
|
State the interaction |
No interaction. X-ray Photon passes through the atom unchanged and leaves the atom unchanged |
|
State the interaction |
Absorption of energy and photo-electric effect.Absorbed by the patient in radiopaque areas . Absorbed by the patient in radiopaque areas
30% of the 1% |
|
State the interaction |
Compton scatter. When the X-ray photon is deflected from its path during Passage through matter. 62% of the 1% |
|
State the interaction. |
Coherent scatter. When an x-ray Photon has its path altered by matter. 8% of the 1% |
|
|
Velocity |
The speed of the wave |
|
|
Transformer |
Used to increase or decrease voltage |
|
|
General radiation |
70% of the 1% When a photon hits the nucleus Produces more energy than characteristic radiation |
|
|
Characteristic radiation |
30% of the 1% When a photon hits an electron |
|
|
Two types of radiation |
Particulate and electromagnetic |
