  1. Radiation sources and source housing assemblies will be installed and serviced only by Stock Equipment Company or other service company representatives who are specifically licensed to provide such services.
  2. During the initial installation, a comprehensive radiation safety survey and source leak test will be performed. Each source will be clearly labeled, CAUTION - RADIOACTIVE MATERIAL, and with a specific description of the radionuclide, activity and date of the activity assay. A controlled area will be established where occupied spaces may exceed 2 millirem in any one hour.
  3. Key control of each source housing shutter lock will be exclusively through the individual(s) designated by the UNC-Chapel Hill Radiation Safety Committee and the UNC-Chapel Hill Radiation Safety Officer or designee.
  4. Any proposed adjustment, relocation or exchange of a source or source housing assembly shall be carried out only under a specific Radiation Work Permit issued by the UNC-Chapel Hill Radiation Safety Officer or designee.
  5. Any entry by an individual into a space intended for the primary radiation source field shall only be under a specific Radiation Work Permit issued by the UNC-Chapel Hill Radiation Safety Officer or designee. The Radiation Work Permit shall specifically describe how the source shutter is to be locked in the "OFF" position, the pre-entry radiation surveys to be conducted, personnel monitoring to be provided and supervisory conditions for the entry. A UNC-Chapel Hill Radiation Safety staff member shall be present through each entry.
