, 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:
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
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, shielding - ✔✔What are the three principal methods used to protect
limited operators from unnnecssary radiation exposure?
Apron, Glove, Thyroid shield - ✔✔What are types of personnel radiation shielding
Scattered radiation from the patient - ✔✔Personnel shielding must be worn on the rare
occasion on which the limited operator may need to remain in the radiographic room
during an exposure to assist the patient in maintianing the proper position. What is the
source of the greatest radiation hazard under this circumstance?
Leakage - ✔✔What is the term for radiation that escapes from the x-ray tube housing
