AGREEMENT STATE REPORT - LOST IODINE-125 SEED

The following information was provided by the Wisconsin Department of Health Services, Radiation Protection Section (the Department), via phone and email:

"On February 7, 2025, the Department received a notification that Gundersen Clinic, Ltd (the licensee) was unable to locate a radioactive seed containing a maximum of 100 microcuries of iodine-125. The seed was identified by the licensee as missing on February 4, 2025. The licensee completed an investigation by February 7, 2025, and submitted a written report to the Department. The licensee determined that the seed was likely disposed of as non-radioactive waste following the successful implantation of other seeds. The exact date of the disposal is unknown, but the licensee determined it occurred between November 20, 2024, and February 4, 2025, which are dates when the licensee's seed inventory was fully reconciled. The Department performed a reactive inspection on February 27, 2025, and considers this event closed. The seed is an IsoAid model IAI-125A from lot number 95130; the seeds are not assigned individual serial numbers."

Wisconsin event report ID: WI250002

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 - LOST AND RECOVERED GAUGE

The following information was provided by the Arizona Department of Health Services (The Department) via email:

"The Department received notification that an Instrotek 3500 Xplorer nuclear moisture/density gauge fell off the back of a truck in front of Lake Havasu High School. The technician returned to retrieve the gauge approximately 30-45 minutes later. The gauge contains 10 millicuries of Cs-137 and 40 millicuries of Am-241. The Department has requested additional information and continues to investigate the event.

"Additional information will be provided as it is received in accordance with SA-300."
