Title	Agreement State Report - Package Received Containing Leaking Sources
Event Description	The following was received from the State of California via email: On Jan. 26, 2012, [the] NRC sent an e-mail to RHB [Radiation Health Branch] management stating that General Nucleonics, Inc. had 22 boxes containing Inflight Blade Inspection (IBIS) devices containing Sr-90 sources (500 microcuries each, Generally Licensed devices) returned to them from the Dept. of the Navy. When the packages were opened, it was discovered that 11 devices were damaged and 5 had removable contamination above 0.005 microcuries. The source manufacturer is QSA Global (formerly AEA Tech), model was Amersham/ now GNI PN # 12205-5 and were installed into GNI PN 12210-1 IBIS Pressure Indicators. Leak testing was performed on 1/11/2012. Source # 3482 / IBIS # 1798, leak test results: 0.13 microcuries of contamination; Source # 1673/ IBIS # 095, leak test results: 0.38 microcuries of contamination; Source # 235 / IBIS # 288, leak test results: 0.30 microcuries of contamination; Source # 2926/ IBIS # 371, leak test results: 0.15 microcuries of contamination; Source # 2843/ IBIS # 378, leak test results: 0.22 microcuries of contamination. All indicators were placed into sealed bags and placed into a glove box. The source receiving and testing areas were checked for contamination and none was found. Each IBIS was installed on a U.S.N. CH-53 Sikorsky helicopter for 'warning' of incipient blade failure. Damage had occurred to the top of the indicators, source capsules had been damaged and the source retaining rods were bent from their normal vertical positions. General Nucleonics will be eventually disposing of these devices through a radioactive waste broker. CA 5010 #: 012612
