Title	California Agreement State Report - Leaking Iodine-125 Brachytherapy Seeds
Event Description	The following information was obtained from the State of California via email: UCLA contacted the Brea office of RHB [Radiologic Health Branch] to report a leaking source of I-125 brachytherapy seeds. Initial survey of the packaging, upon receipt, did not show any contamination. Subsequent testing showed 1.8 microCuries of contamination. The order was for 19 seeds, 16 for treatment, one for calibration and 2 for spares. A physician was preparing an eye plaque using the 16 seeds. A dish of acetone was used to remove glue from the seeds. A radiation survey discovered that the dish had become contaminated with I-125. The patient's procedure was cancelled and EH&S [Environmental Health and Safety] personnel were notified about the issue. EH&S collected all 19 seeds and performed a leak test on the 16 treatment seeds by soaking them in isopropyl alcohol. The fluid was analyzed on a liquid scintillation counter which found 1.8 microCuries of removable contamination. Per 10 CFR 35.3067, a licensee shall file a report within 5 days if a leak test required by 35.67 reveals the presence of 185 Bq (0.005 uCi) or more of removable contamination. RHB is requesting UCLA to obtain copies of the leak tests performed by the manufacturer to determine if the seeds were leaking prior to being shipped to UCLA. These copies will be in the final report. If the seeds were discovered to be shipped in a compromised condition, the Virginia Division of Radiological Health will be notified since the manufacturer (Best Medical International, Inc. of Springfield, Virginia) is located within their jurisdiction. California Report Number: 5010-081611
