The following information was received from the
Wisconsin Department of Health Services (the Department) via email:
On February 7, 2023, the Department was notified by phone call from a physics consultant for the licensee that a package containing radioactive material being shipped by a common carrier from Wisconsin to Burbank, California on December 24, 2022, did not arrive at its destination. The package contained an Eckert & Ziegler Model HEGL-0133 sealed line source (s/n T1-924). The source contained 10 millicuries of Gd-153 on manufacturer's assay date of October 1, 2020. The licensee calculated the activity at the time of shipment to be 0.972 millicuries on December 24, 2022. The courier was contacted by the licensee on February 2, 2023, and the courier's last record for the package shows it located in Memphis, TN on December 24, 2022. The current location of the package is unknown. A lost shipment claim has been made with the courier.
Event Report ID Number: WI230002
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.
