| Title | Agreement State Report - Loss of Yellow Ii Package Containing Approximately 61 Mci of Liquid Tl-201 | |
| Event Description | The following is a synopsis of the report received via email from the Illinois Emergency Management Agency (Agency):
The Agency was contacted the morning of 9/14/20 by the licensee to report a Yellow-II package containing approximately 61 mCi of Tl-201 had not arrived at its final destination. There is no reason to suspect intentional diversion or criminal activity. The 12 inch x 6 inch x 6 inch package was labeled Radioactive Yellow-II with a transport index of 0.4 and was shipped via a commercial carrier. The package contained six shielded vials of diagnostic radiopharmaceutical liquid thallium-201. It was shipped from the licensee address on Tuesday, 9/8/20 with an assay activity of 225 mCi. The package was expected to arrive at the final destination, but as of 1600 CDT on Friday, 9/11/20, the package had not reported any movement after reaching the commercial carrier hub at Memphis, TN. As a result, the licensee contacted the recipient, as well as the radiation safety officer of the commercial carrier. The licensee contacted the Agency to report the package as lost. The last known location remains as the commercial carrier hub. No updates were available as of 9/21/20. The Tl-201 was shipped in a shielded container and does not represent a significant exposure hazard. The remaining activity as of 9/21/20 is 12 mCi. Unshielded, this dose would give rise to about 1.1 mR/hour at one foot. This quantity of material is over the NRC reporting requirement and is being reported within the required 30 day timeline. Illinois Item Number: IL200015 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.
