| Title | Ge-68 Source Missing Following Maintenance |
| Event Description | The following is a summary of information provided by the licensee via phone and email:
The licensee reported two missing Ge-68 sources with an activity of 0.312 mCi per source. The sources were stored on a PET CT mobile imaging unit used throughout the State of Michigan. The mobile unit went for repair to TDC Trailer in Rensselaer, IN. While the unit was at TDC Trailer, the unit needed a structural repair which required items in the camera room to be removed from their designated place. The trailer repairman unbolted the source holder from the floor and moved it to the hot lab and placed it in a radiopharmaceutical dose container. The licensee believes the sources were inadvertently picked up by PetNet Radiopharmacy as part of their routine pick up of empty radiopharmaceutical cases on August 16, 2023.
There were two rod sources missing from PETCT 142. The medical physicist estimates that the dose resulting from these sources over their lifetime to be 31 mSv at 1 meter from the unshielded sources. Notified R3DO Skokowski, 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.
