(Answer with A, B, C, or D)
a. Perform radiographic operations independently
b. Be responsible, at the site where sealed sources are being used, to ensure all license
conditions and regulations are complied to
c. Manipulate the sealed source without direct supervision
d. Perform all radiographic operations while under the direct supervision of a certified
radiographer
, D - Correct Answer -Whenever an exposure device is not under the direct surveillance of a
radiographer or his assistant, it must:
(Answer with A, B, C, or D)
a. Be locked and hidden from view
b. Be locked and chained to a fence
c. Be locked and placed next to the transport vehicle
d. Be locked with the key removed, then locked within a designated storage area
C - Correct Answer -Source guide tubes are primarily used to:
(Answer with A, B, C, or D)
a. Provide some shielding of the sealed source during transit to and from the exposure device
b. Provide a visual indication where the sealed source will travel
c. Provide a protected means to project the sealed source to and from the exposure device to a
fixed focal point
d. Provide a handle to drag the exposure device from one location to another
