what statements are correct regarding the link between
radiation and genetic effects - Answer-The link has been
demonstrated in animal studies .
Increased risk to humans cannot be predicted with respect
to an individual.
The changes in kilovoltage (kVp) will result in the greatest
reduction of patient dose, when milliampere-seconds
(mAs) is adjusted to compensate for the change - Answer-
Increase kVp by 30%
The following image receptor (IR) system speeds will
result in the lowest patient dose - Answer-Faster speed IR
system
The primary purpose of using gonad shields - Answer-
reduce the likelihood of genetic effects
Are gonad shields - Answer-Contact and shadow
,2|Page
gonad shielding should be used - Answer-when the
gonads are within 5 cm of the radiation field
the greatest cause of unnecessary radiation to patients
that can be controlled by the limited operator is - Answer-
repeat exposures
the limited operator can reduce repeat exposure - Answer-
clearly instructing patients
how does the x-ray beam restriction minimize patient
exposure - Answer-it limits the radiation field to the area of
interest
what is the device that allows the limited operator to vary
the size of the radiation field - Answer-collimator
how does filtration reduce patient exposure - Answer-
removes longer-wavelength photons
,3|Page
The National Council on Radiation Protection and
Measurements(NCRP) recommendation for the amount of
total filtration - Answer-2.5 mm Al equiv
Three principal methods used to protect limited operators
from unnecessary radiation exposure - Answer-time,
distance, and shielding
The following is not a type of personal radiation shielding -
Answer-Shadow
personnel shielding must be worn on the rare occasion
during which the limited operator may need to remain in
the radiographic room during an exposure to assist the
patient in maintaining the proper position. What is the
source of the greatest radiation hazard under this
circumstance.? - Answer-scattered radiation from the
patient
the term for radiation the escapes from the x-ray tube
housing - Answer-leakage radiation
, 4|Page
why are limited operators prohibited from activities that
result in direct exposure to the primary x-ray beam -
Answer-they are considered occupationally exposed
individuals
distance, as a method used to limit operator exposure,
means that - Answer-the operator should maximize the
distance from the source during an exposure
shielding worn for personnel protection is designed to
attenuate what source of exposure - Answer-scatter
radiation
the acronym for a common type of personnel dosimeter -
Answer-TLD
What is the recommended placement for personnel
dosimeter on the body of the limited operator - Answer-the
badge should be worn in the region of the collar on the
anterior surface of the body and outside the lead apron, if
worn
