The following report was received via facsimile:
The Radiation Safety Officer (RSO) for Virginia Tech notified the Virginia Radioactive Materials Program on September 23, 2011 that a leaking source had been identified on June 28, 2011. The source was an 8 millicurie (April 1989) nickel-63 source used in a Varian gas chromatograph. The source was contained in a detector kit model 02-001972-00, serial number A7074. The gas chromatograph was no longer used. While preparing the unit to be surplussed, the RSO identified contamination of 0.07 microcurie in the area where the ECD (electron capture detector) had been installed. The RSO reported that he did not report the leaking source in June because leak tests of the ECD itself showed no continuing leakage. The RSO indicated that the gas chromatograph would be decontaminated and that procedures would be modified to specify the required five-day reporting requirement for a leaking source to prevent recurrence of late reporting.
