ENS 5690822 December 2023 08:00:00Agreement StateAgreement State - Contaminated PackageThe following information was provided by the California Department of Public Health, Radiation Health Branch (RHB) via email: On 12/22/2023, the (University of California, San Francisco) notified RHB that a shipment of F-18 radioactive materials received from SOFIE CO FKA ZEVACOR PHARMA (license number: CA-RML 7131-43) was contaminated. The licensee reported that their contamination wipe tests ranged from 65,000 counts per minute (cpm) to over 100,000 cpm per 300-centimeter squared wipe area using a wipe counter with an efficiency of 25 percent. This amount exceeds the non-fixed radioactive contamination limits specified in Department of Transportation regulations 49 CFR 173.443 of 240 cpm per cm squared for beta and gamma emitters and is reportable under 10 CFR 20.1906(d)(1). RHB is in contact with SOFIE and will be investigating this matter further.
