| Title | Lost Source |
| Event Description | The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:
On August 7, 2024, the Department was notified by the licensee that they had lost a Humboldt model 5001 EZ moisture density gauge. The gauge contains a 40 millicurie americium - 241 source and an 8 millicurie cesium - 137 source. The gauge was used at a temporary job site and had been placed in the back of a pickup truck to transport back to its storage location. The technician failed to secure the gauge in the truck and did not raise and secure the tailgate. When the technician arrived at the office, they found the gauge was missing. The technician drove the route they had taken looking for the gauge but did not find it. They then notified their radiation safety officer (RSO). The licensee has contacted the Houston Police Department and notified them of the loss. The licensee stated the cesium source rod was locked in the fully shielded position. The RSO stated that the technician and a district RSO are still out looking for the gauge at the time of this report. The RSO stated the gauge would not create an exposure risk to any individual. Additional information will be provided in accordance with SA 300. Texas Incident #: I-10119
The following information was provided by the Texas Department of State Health Services (the Department) via email: On August 9, 2024, the licensee reported that they had recovered the gauge. An individual was driving on the road where the gauge had fallen out of the truck and recognized what it was and picked it up. He found the contact information on the gauge container and called the licensee. The licensee has the gauge in its storage location. The licensee inspected the gauge and stated that the gauge was in good condition. Notified R4DO (Vossmar), NMSS Events Notification, ILTAB, and CNSNS (Mexico) via email. 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.
