Due to the change in employees, the location of these devices is unknown.</br>The licensee failed to properly transfer or dispose of the devices (serial numbers 4377, 6055, 6273, 6202, and 7067). The facility manager is currently trying to reach out to past employees for information. The Agency has reached out to the distributor to try and locate the devices.</br>The quantity of radioactive material involved, while unlikely to be dangerous to the public, is reportable within 30 days to the Agency and the U.S. NRC. Investigation is ongoing, and any updates will be reported.</br>Illinois Event Number: IL250040</br>* * * UPDATE ON 12/15/2025 AT 1309 EST FROM KIMBERLY STICE TO ERNEST WEST * * *</br>The following is a summary of information provided by the Illinois Emergency Management Agency via email:</br>The facility manager was able to locate two of the devices (serial numbers 6055 and 7067) on 10/31/2025.
