EN Revision Text: AGREEMENT STATE REPORT - LOST SOURCE
The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:
"As a result of an ongoing Agency investigation into unresponsive general licensees, the Agency became aware of one (1) generally licensed fluorescence analyzer device containing 40 millicuries of Cd-109 (Cat 4 source) that is missing.
"Reportedly, in 2023, RCM Laboratories Inc (Hinsdale, Il) ceased operation, per a former employee. There is no indication of intentional theft/diversion, rather the result of an office closure and poor accountability.
"The licensee failed to properly transfer or dispose of the device, a Niton LLC XLp-300A (serial number: 24555). The Agency investigated, and per the real estate agency [which owns the building], the building is empty and confirmed no equipment is in the building.
"The quantity of radioactive material involved is reportable immediately to the Agency and the U.S. NRC."
Illinois Event Number: IL250041
* * * UPDATE ON 10/07/2025 AT 1143 EDT FROM GARY FORSEE TO KERBY SCALES * * *
The following update was provided by the Illinois Emergency Management Agency (the Agency) via email:
"On October 2, 2025, the individual previously associated with the general licensee contacted the Agency and provided appropriate documentation showing the device was properly decommissioned and returned to the manufacturer. The device had been moved to another location without appropriate notice to the Agency. Pending no new data, this matter is considered closed."
Notified R3DO (Edwards and Ziolkowski), NMSS Events Notification, and ILTAB via email.
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 - UNABLE TO RETRACT SOURCE
The following information was provided by the Wisconsin Department of Health Services Radiation Protection Section (the Department) via email:
"On September 23, 2025, the Department received notification that, on the same date, the licensee was unable to retract a radiography source containing approximately 12.5 curies of Ir-192 into the fully shielded position. The licensee could not immediately determine the cause of the event. The QSA 880 Delta radiography camera was secured inside a locked fixed radiography vault, and the boundaries of the restricted area were under continuous surveillance by a radiographer. On September 24, 2025, the licensee was able to successfully retract the source to the fully shielded and secured position. The licensee is [removing] all the associated equipment [from] service and inspecting the equipment to determine cause of the event. The Department will perform an investigation."
Wisconsin Event Report ID No.: WI250013
