Event Notification Report for March 18, 2026

AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE FAILED TO RETRACT

The following information was provided by the Nebraska Department of Health and Human Services (DHHS) via phone:

On March 9, 2026, at approximately 1430 CDT, while attempting to retract the source assembly following an exposure, the licensee radiography crew noted that the camera auto locking feature did not engage and the crew survey meter showed elevated readings. The radiography crew expanded their boundary at the job location and placed lead blankets over the source in an attempt to reduce area dose rates. The licensee radiation safety officer (RSO) was contacted to respond to the job site to perform source recovery, as the RSO is qualified in that activity but not the radiography crew. The RSO recovered the source at 1934 CDT. The drive cable was found broken.

The highest personal dose reported by the radiography crew was 41 mrem. The RSO received 4 mrem.

AGREEMENT STATE REPORT - CONTAMINATION EVENT

The following information was provided by the Illinois Emergency Management Agency and Office of Homeland Security (the Agency) via email:

"The Agency was contacted at approximately 1400 CDT on March 11, 2026, by the radiation safety officer for Loyola University Medical Center to advise a package containing F-18 had been received which had external removable contamination exceeding the limits in 49 CFR 173.443. Multiple sides of the package were contaminated, and a single wipe covering an area of 100 centimeters squared yielded 648,000 disintegrations per minute (dpm). The package was received from PETNET Solutions Inc. radiopharmacy in Elk Grove Village, IL. Loyola University Medical Center indicated no personnel or areas [at their site] were contaminated as a result of the package.

"The PETNET site was closed at the time of the report. The corporate radiation safety officer was contacted, and they indicated no awareness of a contamination incident. The courier was specific to PETNET, and no reports of other contaminated packages have been received. Inspectors will perform a reactive inspection [at the PETNET site] to determine the root cause and corrective actions. At this time, this incident is not suspected to result in any public/occupational exposures exceeding regulatory limits. Loyola University Medical Center contacted the final carrier immediately and met necessary reporting timelines. This report will be updated as information becomes available."
