GRADED | WITH EXPERT SOLUTIONS
restrict the XR beam to the clinical area of interest - correct
answer-As a professional radiographer, the practice of ALARA
requires you to
prime - correct answer-The factors that affect XR emission under
the direct control of the radiographer are called_ factors
beam quality - correct answer-Milliamperage-second (mAs)
directly affects all of the following EXCEPT
mA & filtration - correct answer-The factors that directly affect XR
quantity are
kVp & beam filtration - correct answer-The factors that directly
affect XR quality are

6.3 x 10(18) - correct answer-If 1 coulomb is equal to 6.3 x 10(18)
electron charges, how many electrons flow from cathode to anode
1 second
6.3 x 10(15) - correct answer-If 1 ampere equals a flow of 6.3 x
10(18) electrons per second, how many electrons flow from
cathode to anode in 1 milliampere?
increase 2-fold - correct answer-As the mA doubles, the number
of electrons flowing from cathode to anode
XR beam quantity - correct answer-The product of tube current 7
exposure time is equal to
change the mAs from 15-21 mAs - correct answer-In order to
increase radiographic film density by 40% the radiographer would
directly proportional - correct answer-The relationship between
mAs & exposure is

the reciprocity law - correct answer-The reaction of a
photographic film to light is equal to the product of the intensity of
the light and the duration of the light exposure.
cause the electrons to travel faster from cathode to anode -
correct answer-Increasing the kVp for an exposure will
greater energy - correct answer-Increasing the energy of an
incident electron will result in the production of an XR photon with
radiographic film density - correct answer-Kilovoltage is the
primary controlling factor of
contrast - correct answer-Adjustments in kVp should be used to
control radiographic
kVp - correct answer-XR beam penetrability is primarily controlled
by
