AGREEMENT STATE - FOUND DENSITY GAUGE
The following was received by email from the Texas Department of State Health Services [the Agency]:
"On June 1, 2023, a steel mill notified the Agency that a load of scrap coming into their facility set off the radiation alarm. The source was identified as an inline-type density gauge and it was secured at their facility until more information could be identified on the device to determine the owner. On June 5, 2023, the facility found a phone number on the gauge that stated to call Schlumberger if the gauge was found. Schlumberger was contacted and stated the gauge had been sold to Liberty Oilfield Services INC. The Agency and steel mill contacted the licensee which picked up the gauge the same day. The gauge was a Thermo-Fisher model 5192, Serial # B7615 containing 200 mCi (7.4 GBq) of Cesium-137. An investigation is ongoing into how the licensee lost possession of the gauge."
Texas Incident number: 10024.
NMED National Event number: TX230026.
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.

AGREEMENT STATE REPORT - STOLEN/FOUND SOURCE
The following information was provided by the Pennsylvania Department of Radiation Protection (DEP) via email:
"On June 1, 2023, an employee of the licensee reported to police that their vehicle, with a nuclear density gauge in it, was stolen earlier that day. The vehicle was located and returned to the employee within a few hours. The gauge was still properly stored in the trunk and untouched with no evidence that the trunk lock, gauge chain, chain lock, or gauge case had been tampered with. The DEP has been in contact with the licensee and will update this event as soon as more information is provided.

PARTIAL LOSS OF CRITICALITY ACCIDENT ALARM SYSTEM
The following information was provided by the licensee via email:
"On June 1, 2023, during inclement weather, a Phase 2 CAAS [Criticality Accident Alarm System] detector fault was received. Troubleshooting efforts indicated two CAAS nodes are impacted and SBM1005 [Process Services Corridor] was evacuated. The affected detectors are located in the north end of the SBM1005 Process Services Corridor. Compensatory measures are implemented in the affected area to support maintenance troubleshooting efforts.
"UUSA is reporting this event per 10 CFR 70.50(b)(2)."
