Title	Agreement State - Leaking Sealed Source
Event Description	On May 6, 2004, a leak test sample from a Hewlett Packard 5890 Gas Chromatograph, with ECD Model # 19233, was leak tested for source Serial No. L6180 [Nickel - 63, current activity 13.48 milliCuries]. The initial leak test resulted in removable activity of approximately 9250 disintegrations per minute (dpm) or 0.0042 microCuries, near leak test limits. A second test was repeated on May 7, 2004, which resulted in 194,000 dpm or 0.087 microCuries of removable activity on the vent tube, which was well above the leak test limit. Minor removable contamination (approximately 100 counts per minute (cpm)) was detected on the interior of the case, the inlet tube sample (approximately 100 cpm), and the vent tube cap (approximately 1750 cpm). The source was confiscated by the University's radiation safety staff to a secure location at the Radiation Safety Office. The last leak test was conducted on December 17, 2003, with results indicating no contamination. The source will be returned to the manufacture or disposed of as radioactive waste. The direct cause of the loss of the source's integrity is not known. The written report was received by this agency May 17, 2004, but was not delivered to Incident Investigation until July 7, 2004. No violations have been cited. This incident was closed July 7,2004. TX Incident number I-8138
