EN Revision Text: AGREEMENT STATE REPORT - LOST / MISSING SOURCES

The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:

"As a result of an Agency investigation into an unresponsive general licensee, three (3) x-ray florescence analyzers containing 30 millicuries each of Am-241, are being reported as lost or missing. The quantity of radioactive material involved, while unlikely to be dangerous to the public, is immediately reportable to the Agency and the U.S. Nuclear Regulatory Commission when lost or missing. Agency staff will conduct a reactive inspection to determine if the portable analyzers are still on site or any additional information is available.

"The company, Bar Source International, LLC (d/b/a Pro Metals LLC) was operating in Rochelle, IL as recently as March 2020. At that time, the company was in possession of a Thermo Niton XLp-818 (s/n 10597), XL3p-800 (s/n 33072) and XL258006651 (s/n 96513). The company has been unresponsive to Agency requests and, according to a former employee, closed sometime on or after March 2020."

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 - STUCK SHUTTER

The following report was received by the Texas Department of State Health Services (the Department) via email and phone:

"On August 21, 2025, the Department was notified by the licensee that the shutter on a Vega America Inc. SH-F1 nuclear gauge was found to be stuck in the open position during routine testing. Open is the normal position for the shutter. The licensee reported that there is no risk of additional radiation exposure to members of the general public or radiation workers due to this on/off mechanism failure. Additional information will be provided as it is received in accordance with SA-300."

Texas incident Number: 10218
Texas NMED Number: TX250038

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.
