By regulation, x-ray tube leakage radiation can be no more than: CORRECT
ANSWERS 100 mR/hour @ 1 meter
The primary purpose of the glass or metal enclosure is to CORRECT ANSWERS
maintain a vacuum within the tube.
The target window is usually approximately CORRECT ANSWERS 5 cm^2
The rotating anode design uses a disc whose core is made of CORRECT ANSWERS
molybdenum
Tungsten is used to coat the anode disc because it has. CORRECT ANSWERS a high
atomic number
The portion of the induction motor that is outside the tube enclosure is the CORRECT
ANSWERS stator
the process of a series of outer-shell electrons filling inner-shell vacancies is known as
CORRECT ANSWERS characteristic cascade
Bremsstrahlung interactions may occur only when the incident electron interacts with
CORRECT ANSWERS the force field around the nucleus.
The energy of the brems photon depends on the CORRECT ANSWERS -energy of the
filament electron as leaves the tungsten atom
-strength of the attraction b/t the electron and the nucleus
-original energy of the filament electron
Which of the following radiographic factors will affect x-ray quantity? CORRECT
ANSWERS -Kilovoltage-peak (kVp)
-Source-image-distance (SID)
