Title	Found Licensed RA-226 Sources
Event Description	The following is a synopsis of a telephonic report from the RSO at South Dakota State University: On about October 14, 2021, the University was contacted to collect two orphaned Ra-226 sources from a residence of a former employee. One source was within an Ionization Cell Model A-4149, the other was contained in a lead pig. Swipe surveys did not detect any leakage from the sources. Both sources are identical, 0.056 mCi Ra-226, Dated 09-66, Barber-Colman Company, Rockford, Illinois. There are no serial numbers to determine the original owner. The deceased employee also worked in the chemistry department at Southwest Minnesota State University. The Radiation Safety Officer has properly secured the items and is herby notifying the NRC of the possession of this licensed material, which is allowed by their license. 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.
