| Title | NON-AGREEMENT State Report - Lost Troxler Gauge |
| Event Description | The following information was provided by the licensee via phone conservation:
An NRC licensee lost a portable moisture density gauge while in transit to a testing site. The licensee inadvertently drove to the work location with a Troxler gauge on the work vehicle tailgate. The gauge was last known to be in possession by the licensee at the intersection of Kentucky and Diamond Avenues in Evansville, Indiana. The Troxler Model 3400, SN 20494, contained 9 mCi, Cs-137 and 1320 mCi, Am-241/Be. 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.

The following is a synopsis of information that was provided by the licensee via email: The site radiation safety officer received a call on Friday, November 17, 2023, from the job site informing them that the gauge was returned. The licensee returned to the job site, retrieved the gauge, performed leak tests, and notified the NRC Region III Office (Jason Draper). Notified R3DO (McCraw), NMSS Events, and ILTAB via email.
