Event Notification Report for July 30, 2026

AGREEMENT STATE REPORT - STUCK SHUTTER

The following information was provided by the Pennsylvania Bureau of Radiation Protection (the Department) via email:

"On July 22, 2026, the licensee notified the Department of a shutter failure that was discovered on July 21, 2026.

"On July 21, 2026, the licensee discovered that a fixed gauge shutter was stuck open. The gauge is a Global Gauge Corporation (formerly E.S.C. Resources, Inc.) model SH-6000, serial number 70705 containing 2 Ci of Am-241. The gauge access area has been shut down. The licensee contacted a service provider and Global Gauge Corporation.

"The Department will perform a reactive inspection."

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following summary of information was provided by the Ohio Bureau of Environmental Health and Radiation Protection via email:

On July 19, 2026, at 0300 EDT, a Troxler model 3440 (serial number: 24472) moisture density gauge (8 mCi Cs-137, 40 mCi Am-241/Be) was stolen from a house in Johnstown, Ohio which was being used as a temporary storage location between two construction projects. The video footage showed a person wearing a ski mask gaining access to the locked house via an exterior storm entrance into the locked basement, by using bolt cutters. The gauge was in a locked garage, hidden out of sight, and chained to the wall using a wall anchored eyebolt. The chain was cut with bolt cutters. The Wi-Fi connection was cut, possibly to disable the cameras. The contractor in charge of the field office has filed a police report.

Ohio event number: OH260006

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 - UNPLANNED CONTAMINATION

The following is a summary of information provided by the Oregon Health Authority, Radiation Protection Services (OHA) via email:

OHA was contacted by Laurelwood Animal Hospital about an event on 7/20/2026 involving a technician receiving skin contamination on their arm. A drop of I-131 forming at the end of a syringe fell off onto their protective gown and the attempt to blot the drop with a chemo pad pushed the contamination through the gown onto the skin. The technician removed the gown and washed their arm for 4 minutes. The maximum contamination level detected on the skin was 2200 counts per minute (cpm) at one inch from contact. The Radiation Emergency Assistance Center/Training Site (REAC/TS) was notified and consultants provided assistance. The technician will keep their forearm covered for a few days while the iodine decays.

Oregon Incident Number: 26-0038

AGREEMENT STATE REPORT - LOST GAUGE

The following information was provided by the California Department of Public Health (the Department) via email:

"On July 21, 2026, at approximately 1525 [PDT], the licensee notified the Department that they had discovered one of their nuclear portable gauges was missing. There were no signs of a break-in. The gauge is a Troxler model 3430 (serial number: 35107) [moisture density gauge] containing approximately 9 mCi of Cs-137 and 44 mCi of Am-241/Be both in special form. The last known date of possession was on June 25, 2025, during receipt from its routine annual calibration. It is unknown when the gauge went missing. The Department is investigating this incident."

AGREEMENT STATE REPORT - LOST EXIT SIGNS

The following is a summary of information provided by the Colorado Department of Public Health and Environment via email:

The licensee declared eight exit signs as lost on July 9, 2026. The exit signs were manufactured by SRB Technologies, model number BXU20GS, and contained 17.5 Ci of tritium each.

MEDICAL EVENT

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

"On 7/22/26, three prostate seed implants were scheduled at the Delaware Surgery Center, 200 Banning Street, Dover, DE, NRC license number 07-35521-01.

"The first implant was with I-125 seeds in preloaded cartridges (vendor Theragenics) used with a Mick applicator. It was completed successfully.

"The second case was with a Pd-103 (200) anchor-seed in preloaded cartridges (Theragenics) with a Mick applicator. During the beginning of this second case (first needle seed deployment), the sixth seed could not be deployed. The Mick plunger would not advance past the cartridge. It was felt that the cartridge might be defective, and an attempt was made to remove it, so that a new cartridge could be used. The cartridge did not slide out easily, and when it did the Mick plunger was pushed a few times. It was noticed that a seed had broken in half and fell onto the table. Both of the pieces were retrieved and stored in a shielded container. The Mick gun was surveyed and showed background activity level. The difficulty in pushing seeds through the cartridges persisted with a new cartridge and a new Mick gun. After the sixth seed was deployed, the plunger would not advance again. While checking the Mick gun and the cartridges at the table to identify the issue, it was observed that the plunger would advance with difficulty, and when the seeds pushed out of the cartridge, they seemed to be adhering to the gun components. At this point, it was decided to abort the case due to the difficulty with this lot of seeds and cartridges, and so that the procedure can be more easily successfully completed at a later date as only 6 out of the 97 planned seeds were implanted. After all the seeds were counted and stored in their shielded container, the area was thoroughly surveyed, and no trace of residual radioactivity was detected on the table, Mick applicators and the surrounding areas in the room, indicating that the broken seed had not contaminated any of the surroundings. The room was subsequently cleared for the next case.

"The third implant was with I-125 seeds in preloaded cartridges (vendor Theragenics) used with a Mick applicator. It was completed successfully.

"The vendor, Theragenics, was notified immediately, and will be conducting their investigation."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The total intended dose was approximately 125 gray from the implants. Approximately 6 percent of the intended dose was received by the patient before the procedure was aborted.

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.

CONCURRENT REPORT - FIRE IMPAIRMENT

The following information was provided by the Global Nuclear Fuel - Americas via phone and email:

"At approximately 1500 EDT on July 28, 2026, the New Hanover County Deputy Fire Marshall was notified per State code requirements that the fire suppression system encompassing the fuel manufacturing operation (FMO) was impaired. The backup diesel fire pump was determined to have incorrect fuel in its fuel tank. As a result, the diesel fire pump was removed from service, and recovery activities started. The electric fire pump remained fully operational and available to perform its safety function.

"Because the New Hanover County Deputy Fire Marshall was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c)."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The backup diesel fire pump tank was drained, and the lines and filter will be changed and refilled with the correct fuel.
