| Title | Missing Source |
| Event Description | The following information was received from the Commonwealth of Virginia via email:
On January 5, 2021, the licensee reported that 34.02 microCuries of I -125 Aqueous Solution (Musk Tracer) was lost. The source was received on December 8, 2020. The licensee's technologist opened the package and checked if it needed to be refrigerated. The technologist verified the source was in the package and determined that the source did not need to be refrigerated. Then the technologist left the source in the package on the floor with the other items in the inventory area. Upon review of the receipt log of radioactive materials, it was noted that this shipment (package) was never logged-in, whereas other products received that day were included in the log, and the source could not be located. On 12/11/2020, the RSO [Radiation Safety Officer] was notified about the possible loss of the package. A search was conducted in the facility, but the licensee was unable to locate the source. The Facilities Department was alerted that there was a missing shipment (source), but five days had already passed. The licensee stated that it was too late to go through the dumpsters. The licensee believed that the package was unknowingly disposed of in a dumpster. However, the search is continuing. The licensee will submit the possible maximum public dose exposure from this source. This report will be updated when the licensee submits their final investigation report. Virginia report no.: VA210001 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.
