The following is a summary of information that was provided by a Wiedenbach Brown representative via phone:

This event was incorrectly reported. Wiedenbach Brown coordinated the disposal of what was believed to be an expired tritium exit sign on behalf of the licensee, AMC Theater Ward Parkway 14.
However, the licensee was in fact adding a new exit sign at a new location within their facility. Therefore, there was no exit sign that needed to be returned for disposal.

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 - FOUND SOURCE

The following is a summary of information received from the Arkansas Department of Health (the Department) via email:

On February 25, 2026, at 1033 CST, the Department received a DOT 10656 permit issued from Tennessee to Arkansas for National Salvage and Service. The salvage company had been contacted by phone on February 24 to inquire about any found radioactive material. The company indicated they had not yet received the shipment back and would provide an update once the returned truck had been inspected.

On March 2, National Salvage and Service contacted the Department to report that the radioactive material had been found. Photographs show an Alnor Dewpointer, serial number 13649. Inside the device's case is a radioactive warning label indicating 2,945 Becquerels (6.25 microcuries) of Ra-226 in powder form, contained inside a screw canister. The canister was unopened and appears undamaged from the scrapping process. National Salvage and Service has bagged the device and placed it in a labeled container.

This source did not appear on any Arkansas GL license records for the site from which the abandoned source was collected (the Tenneco plant, which closed in 2025), and it is believed to have been manufactured prior to regulatory requirements. National Salvage and Service is working toward disposal solutions. The Department will provide an update when the material has been safely relocated.
