LMRT Core Review Questions and
Answers Latest 2026
restrict the XR beam to the clinical area of interest Ans:
As a professional radiographer, the practice of ALARA
requires you to
prime Ans: The factors that affect XR emission under the
direct control of the radiographer are called_ factors
beam quality Ans: Milliamperage-second (mAs) directly
affects all of the following EXCEPT
mA & filtration Ans: The factors that directly affect XR
quantity are
kVp & beam filtration Ans: The factors that directly
affect XR quality are
6.3 x 10(18) Ans: 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) Ans: 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 Ans: As the mA doubles, the number of
electrons flowing from cathode to anode

XR beam quantity Ans: The product of tube current 7
exposure time is equal to
change the mAs from 15-21 mAs Ans: In order to
increase radiographic film density by 40% the
radiographer would
directly proportional Ans: The relationship between mAs
& exposure is
the reciprocity law Ans: 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 Ans: Increasing the kVp for an exposure will
greater energy Ans: Increasing the energy of an incident
electron will result in the production of an XR photon
with
radiographic film density Ans: Kilovoltage is the primary
controlling factor of
contrast Ans: Adjustments in kVp should be used to
control radiographic
kVp Ans: XR beam penetrability is primarily controlled
by
400 mA, 200 ms, 40" SID Ans: All factor remaining
constant, which of the following set of exposure
