The primary purpose of using gonad shields reduce the likelihood of genetic effects
Are gonad shields Contact and shadow
gonad shielding should be used when the gonads are within 5 cm of the radiation field
the greatest cause of unnecessary radiation to patients repeat exposures
that can be controlled by the limited operator is
the limited operator can reduce repeat exposure clearly instructing patients
how does the x-ray beam restriction minimize patient it limits the radiation field to the area of interest
exposure
what is the device that allows the limited operator to collimator
vary the size of the radiation field
how does filtration reduce patient exposure removes longer-wavelength photons
The National Council on Radiation Protection and 2.5 mm Al equiv
Measurements(NCRP) recommendation for the amount
of total filtration
Three principal methods used to protect limited time, distance, and shielding
operators from unnecessary radiation exposure
The following is not a type of personal radiation Shadow
shielding
personnel shielding must be worn on the rare occasion scattered radiation from the patient
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.?
the term for radiation the escapes from the x-ray tube leakage radiation
housing
why are limited operators prohibited from activities that they are considered occupationally exposed individuals
result in direct exposure to the primary x-ray beam
distance, as a method used to limit operator exposure, the operator should maximize the distance from the source during an exposure
means that

shielding worn for personnel protection is designed to scatter radiation
attenuate what source of exposure
the acronym for a common type of personnel TLD
dosimeter
What is the recommended placement for personnel the badge should be worn in the region of the collar on the anterior surface of
dosimeter on the body of the limited operator the body and outside the lead apron, if worn
The NCRP recommended annual effective dose limit for 5.0 rem (0.05 Sv)
occupational exposure
The NCRP recommended monthly effective (or 0.05 rem (0.0005 Sv)
equivalent) dose limit to the fetus for a pregnant worker
Radiation monitoring of personnel is required when 10%
what percentage of the annual occupational effective
dose limit is likely to be received
The conventional (British system) radiation unit to Roentgen
express radiation intensity in the air
The conventional (British system) unit commonly used rem
to report occupational dose to radiation workers in the
United States is the
What is the conventional (British system) radiation unit Rad
of absorbed dose
According to the Bergonie-Tribondeau law, the embryonic tissue cells
following types of cells are most radiosensitive
Type of x-ray photon interaction with the body is Photoelectric
primarily responsible for the radiation dose absorbed
by the patient
