12VAC5-481-2041. Surveys Required.
A. Radiation surveys.
1. In addition to the survey requirements in 12VAC5-481-750, licensees shall make surveys to ensure that the maximum radiation levels and average radiation levels from the surface of the main source safe with the source in the shielded position do not exceed the levels stated in the Sealed Source and Device Registry.
2. The licensee shall make the survey required by subdivision 1 of this subsection at installation of a new source and following repairs to the source shielding, the source driving unit, or other electronic or mechanical component that could expose the source, reduce the shielding around the source, or compromise the radiation safety of the unit or the source.
B. Patient surveys. Before releasing a patient or human research subject from licensee control, a licensee shall survey the patient or human research subject and the remote afterloader unit with a portable radiation detection survey instrument to confirm that the source has been removed from the patient or human research subject and returned to the safe shielded position.
