A device that is designed to shield a beam of radiation and
reduce incidental radiation levels is called a:
A: backscatter screen
B: guide tube
C: collimator
D: source capsule
C
For X-radiography conducted in a shielded, enclosed, and
lockable exposure room, unless additional barriers are added,
radiation dose levels at any location outside the room should not
exceed:
A: 2 mRem in any one hour
,Page 2 of 59
B: 2 mRem in any one hour, except that scattered radiation must
be maintained at less than 1 mRem in any one hour
C: 10 mRem in any 5 minute period
D: 200 mRem in any one month
A
Pocket dosimeters are used to:
A: warn the wearer that a high radiation field is present
B: protect the wearer from radiation up to 200 mR
C: indicate the radiation dose received by the wearer
D: indicate the radiation intensity to which the wearer is exposed
C
Before transporting an exposure device to a field site, the
radiographer must:
A: secure the device against movement in the vehicle
B: place flashing yellow lights on the roof of the vehicle
C: place the exposure device in an overpack
D: transfer the source to a storage container
A

Which of the following is best capable of measuring relatively
low levels of radiation?
A: Ionization chamber survey meter
B: Pocket dosimeter
C: Geiger-Mueller (G-M) counter
D: Thermoluminescent dosimeter
C
In controlling exposure to X-rays, which of the following
statements is true?
A: safe distance calculations must be taken into account for the
build-up factor
B: shielding is less effective than the gamma rays because of the
continuous nature of x-rays
C: radiation area and high radiation area boundaries must be
posted with the same requirements as with the use of gamma
rays
D: because x-ray machines produce noise when energized and
thus alert personnel within close proximity to the tube-head that
x-rays are being generated, they are inherently more safe than
gamma rays devices

C
Overexposures most frequently occur because:
A: personnel have insufficient training in handling and use of
radiation exposure devices
B: radiography exposure equipment malfunctions
C: radiography personnel fail to use survey meters properly
D: radiography personnel are permitted to work without
supervision
C
One mechanism of absorption of radiation by matter is through:
A: Prompt emission of alpha particles
B: Beta capture
C: Compton scattering
D: Neutron emission
