The SC Department of Health and Environmental Control [DHEC] was notified on Friday, November 1, 2013, at 0902 hrs. [EDT], that during routine wipe testing of a Shimadzu GC14A gas chromatograph, an
ECD containing 10 milliCuries of
Ni-63 was found to have removable contamination exceeding 0.005 microCuries. The chromatograph was being tested in preparation for disposal when wipes of the inside of the chamber indicated contamination. The source was removed and properly bagged to prevent the spread of any further contamination. The chromatograph and source are secured in the Radiation Safety Laboratory awaiting disposal by a licensed vendor. The Radiation Safety Officer stated that wipes of the laboratory where the chromatograph had been located were analyzed and no removal contamination had been detected.
The Radiation Safety Officer was advised by Mark L. Windham [South Carolina DHEC] to submit a written report detailing this event to the Department within 30 days. The event is open and pending the licensee's investigation and report to the Department. Updates will be made through the national
NMED system.
