The following is a summary of a phone call with the physicist at the licensee:
The licensee reported that two small sealed sources (Ge-68, roughly 0.7 mCi each) were discovered to be missing from a mobile PET-CT coach that was parked at a location in Rensselaer, IN. This coach was being refurbished at this site. The sources were discovered missing by a service engineer working on the PET-CT unit on 9/13/2021. The entire facility was thoroughly searched with a GM survey meter and the sources could not be located.
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.
