Electromagnetic Radiation
Which is the LONGEST wavelength in the electromagnetic spectrum?
What is RADIO WAVES
The on/off switch can be found on the________?
What is CONTROL PANEL
What is the portion of the tubehead that helps to dissipate heat duringn x-ray production?
What is INSULATING OIL?
Approximately 70% of xrays are produced in the anode and classified as this type of radiation.
What is GENERAL RADIATION
What is the term used when x-ray photons pass through matter (or human tissues) without any interaction?
What is NO INTERACTION?
What is the term used to describe the number of wavelengths that pass a given point in a certain amount of time?
What is FREQUENCY?
Which part of the xray unit aims and shapes the x-ray beam?
What is PID (Position indicating Device)
What area is the "heart"of the x-ray generating system?
This type of radiation occurs at 70Kv and above.
What is CHARACTERISTIC RADIATION?
Which type of interaction is the most common scatter radiation, and accounts for 62% of all scatter.
What is COMPTON?
Visible light has a __________wavelength than X-rays
What is LONGER ?
This part houses all the electrical wires and the external control panel of the tubehead.
What is EXTENSION ARM?
Which area of the tubehead also helps to dissipate heat in addition to the insulating oil?
What is the copper stem in the anode?
Also known as the "useful beam", it is the penetrating x-ray beam that is produced at the target of the anode and exits the tubehead.
What is PRIMARY RADIATION?
This type of scatter radiation accounts for aprox 8% of all interactions, it is a low energy xray photon that interacts with an outer shell electron.
What is COHERENT?
What type of relationship exists between Frequency and Wavelength?
A. Inverse
B. Parallel
What is A. INVERSE
What is the name of the lead plate, which restricts the size of the xray beam?
What is LEAD COLLIMATOR?
Consists of a tungsten wire filament in a cup shaped holder made of molybdenum; supplies the electrons necessary to generate x-rays
What is CATHODE (-)
This term refers to the x-radiation that is created when the primary beam interacts with matter.
What is SECONDARY RADIATION?
This type of interaction with matter occurs 30% of the time and is also termed photoelectric effect.
What is ABSORPTION? ]
Electromagnetic radiation can be either: naturally occurring, man-made, or both
What is BOTH
What is the name of the area that filters out non penetrating, longer wavelength x-rays?
What is Aluminum disks?
Which part contains a tungsten target and copper stem, and converts electrons into x-ray photons?
What is ANODE?
When an x-ray is deflected from its path, it is considered__________radiation.
What is SCATTER RADIATION?
Name the 4 types of Radiation interactions that can occur.
None
Absorption
Coherent
Compton
