, Increase kVp by 30% Which of the following changes in kilovoltage (kVp) will result in the greatest
reductions of patient dose, when milliampere-seconds (mAs) is adjusted to
compensate for the change?
Faster-speed IR system Which of the following image receptor (IR) system speeds will result in the lowest
patient dose?
Contact and shadow Which of the following are types of gonad shields?
When the gonads are within 5cm of the radiation field When should gonad shielding be used?
Repeat exposures The greatest cause of unnecessary radiation to patients that can be controlled by
the limited operator is:
Clearly instructing patients The limited operator can reduce repeat exposures by:
It limits the radiation field to the area of interest How does x-ray beam restriction minimize patient exposure?
Collimator What is the device that allows the limited operator to vary the size of the radiation
field?
Reduce the likelihood of genetic effects What is the primary purpose of using gonad shields during radiography?
Removes longer-wavelength photons How does filtration reduce patient exposure?
2.5 mm Al equiv What is the National Council on Radiation Protection and Measurements (NCRP)
recommendation for the amount of total filtration?
Time,distance, and shielding What are the three principal methods used to protect limited operators from
unnecessary radiation exposure?
Shadow Which of the following is not a type of personnel radiation shielding?
