| Title | Agreement State - Leaking Liquid Scintillation Counter Source |
| Event Description | The following information was received from the State of California Radiologic Health Branch via e-mail:
On June 10, 2009, the RSO for Beckman Coulter Instruments reported that a 21.5 year old Cs-137 source removed during decommissioning from a Beckman Coulter LSC (Liquid Scintillation Counter): model LS 5801 counter (s/n 7015110) was found to have 0.013 microcuries removable contamination. The reportable limit is 0.005 microcuries. It was removed from the LS counter by a Beckman Field Service Technician and returned to the Beckman Coulter facility in Fullerton for disposal, where the leak test was performed. No other contamination was found inside the LS device. The source part number is 598860, lot # ST1022018 - reference date was 12/18/87. The most probable cause of the leakage was the source holder was cracked due to age. Beckman Coulter has determined that the useful life is 8 years for these sources. The company is replacing all sources older than 8 years as corrective action. The State provided additional information indicating that the original source activity was 30 microcuries.
