Event Notification Report for August 22, 2025

AGREEMENT STATE REPORT - MEDICAL EVENT

The following information was provided by the Radiation Health Branch of the Kentucky Department for Public Health and Safety via email:

"On August 26, 2025, the University of Kentucky (UK) Health Center radiation safety officer became aware of a situation that represents what UK believes are a series of possible medical events which occurred from August 22 to August 25, 2025, related to nuclear medicine administrations requiring written directives. Within this date range, a new faculty physician who was in the process of becoming approved as an authorized user (AU) through the UK radiation safety committee (RSC) signed 5 written directives (3 for diagnostic I-131 procedures with a nominal activity of 5 mCi, and 2 for Lu-177 therapy at a 100 mCi activity) despite not having yet received approval under the UK medical broad scope license from the UK RSC. The cases have all been reviewed by a senior AU and no patient harm has been identified. The physician in question has since received approval from the UK RSC. Notifications are in process as required.

"This event is under investigation. University of Kentucky will complete an assessment and implement corrective actions.

"The written report will follow as required in 15 days."

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

STOLEN MOISTURE DENSITY GAUGE

The following information was provided by the licensee via phone:

The licensee reported that an InstroTek model 3500 moisture density gauge (s/n 3478, 10 mCi Cs-137, 40 mCi Am-241/Be) was stolen from a vehicle parked overnight. A licensee employee found the gauge stolen with the locks securing the gauge to the vehicle cut with a bolt cutter. The gauge had been properly secured in its transport case in the vehicle. The licensee has reported the theft to the Jackson Police Department.

THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - POTENTIAL GAUGE DAMAGE

The following information was provided by the Louisianna Department of Environmental Quality (LDEQ) via email:

"On August 22, 2025, the Louisiana State Police notified LDEQ that Smitty's Supply Inc. in Roseland had an explosion and was on fire. The explosion and fire resulted in significant damage to the facility.

"At the time of the incident, three nuclear gauge devices, each containing 100 mCi of Americium 241, were present onsite. These gauges could potentially be affected. The fire was finally extinguished on August 25, 2025. An entry team, including a radiation inspector, will enter the facility today, August 26, 2025, to verify/confirm the status of the gauges and radioactive material."

CONCURRENT REPORT - FIRE IMPAIRMENT

The following information was provided by the licensee via phone and email:

"At approximately 1035 (EDT) on August 22nd, 2025, the New Hanover County Deputy Fire Marshal was notified per North Carolina Fire Code requirements that a fire suppression system riser, which provides sprinkler protection to a portion of the fuel manufacturing operation (FMO), was impaired due to missing ceiling tiles. A fire watch for the affected area has been initiated. Because the New Hanover County Deputy Fire Marshal was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c)."

The NRC regional inspectors were notified.
