Ohio GXMO Study Guide Review
1 Seivert equals 100 - ANS-rem
12:1 - ANS-standard purpose, chest
16:1 - ANS-excessive kVp radiology
5:1 - 6:1 - ANS-Grid cassettes, cell radiography
eight:1 - ANS-trendy reason
ninety nine% of the power of the electrons placing the goal is converted into? - ANS-Heat
A cassette containing movie gets the x-ray beam. The movie now carries a latent image and
will become seen after being processed in a? - ANS-Dark room
A layer of lead foil can be found within the returned of a cassette to save you -
ANS-backscatter
A special mechanism that prevents tube motion at a selected vicinity is? - ANS-Detent
AEC - ANS-Requires accurate positioning, require use of bucky, presents constant
radiographic density
An electronic plate receives the x-ray beam and produces and digital sign this is sent directly
to a computer for processing and digital photo formation? - ANS-Direct/Digital
An improved OID will result in? - ANS-Increased penumbra and decreased picture clarity
Annual dose restrict for an occupationally uncovered radiation employee - ANS-5 rem
Annual dose limit for the overall public - ANS-zero.1 rem
Artifacts - ANS-Quantum mottle, moire sample, light spots, phantom or ghost pix, scratches
or tears, strains, fogging.
As display screen pace will increase, the variety of x-rays needed to produce density will? -
ANS-Decrease
Attenuation - ANS-A lower inside the beneficial beam as it is partly absorbed by way of a
body part
Average annual dose from background radiation - ANS-zero.360
, Below 70 kVp, there aren't any - ANS-characterisitcs
Bremmstrahlung - ANS-has no electrons and hits tough
Bremmstrahlung radiation - ANS-One of sorts of x-rays. Brems is created whilst an electron
enters the tungsten anode of the x-ray tube and misses the tungsten electrons and receives
close to the nucleus. The electron all at once slows down and deviates. The lack of
electricity creates an x-ray photon.
Bucky grid - ANS-Moves, you can push out and pull in and has a ratio of 12:1 - 16:1.
Central Nervous System syndrome - ANS-5000+ rads whole body dose, cause of demise:
multiplied intracranial strain, vasculitis, meningitis.
Characteristic radiation - ANS-One of two styles of x-rays. This is created when an electron
enters the tungsten anode of the x-ray tube and knocks the ok shell out of orbit. This
interaction creates an x-ray photon.
Coherent - ANS-Below 10 kVp
Coherent scattering - ANS-Thompson Scatter.. Interactio takes vicinity at low power
degrees, underneath 10 kVp.
Compton - ANS-Collides with OUTER orbital electron and scatters. 40-one hundred twenty
five kVp
Cumulative dose restrict for fifty 12 months vintage radiation worker - ANS-50 rem
Developer temp is critical and ought to be - ANS-95 tiers F
Digital receptors offer a extensive range of publicity latitude when in comparison to -
ANS-film screen structures
Directly proportional to the amount of the x-ray beam? - ANS-mAs
Do darkish room partitions want to be painted black? - ANS-No!!
Does electromagnetic radiation have mass? - ANS-No
Dose in RAD expanded by using a satisfactory factor offers the dose in.. - ANS-rem
Electromagnetic strength - ANS-x-ray
Fluroscopy is? - ANS-The moving x-ray and pt swallows barium sulfate
Gastrointestinal syndrome - ANS-Death due to excessive harm to intestinal lining, a
thousand-1500 rad entire body dose
