Title	NON-AGREEMENT State Report - Lost Tritium Range Indicator
Event Description	The following is a summary of telephonic information received from the U.S. Army: On December 9, 2021, the Radiation Safety Officer (RSO) was notified that a range indicator for a mortar system, containing a 3.2 Curie Tritium source, had been lost for over a year at the Iowa National Guard in Johnston. The indicator is not removable, so it is unclear how it was lost. Army leadership became aware on November 3, 2021, and a search began. The RSO was notified that the search was concluded, and the source is considered lost. 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.
