AGREEMENT STATE REPORT - STOLEN GAUGE
The following information was provided by the Texas Department of Health Services (Department) via phone and email:
"On May 8, 2025, the licensee reported that at 1245 CDT a Humboldt moisture density gauge containing two sources, an 8 mCi [Cs-137] source and a 40 mCi Am-241/Be source, was stolen from a truck at a jobsite in Houston. The gauge was locked in the bed of the transport vehicle while the gauge operator was in the restroom. The chains holding the gauge were cut and the gauge removed. It was reported to the Houston police department. The licensee reported the handle was in the up position and locked and there is no immediate danger to the public.
"Additional information will be made available in accordance with SA-300 reporting requirements."
Texas NMED # 250027
Texas Incident # 10196
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 - CONTAMINATION EVENT
The following report was received by the North Carolina Division of Radiation Protection via email:
"On May 8, 2025, the licensee reported that a source [Am-241/Be, CPN23, 50mCi] was ruptured during a source recovery task. The source was being removed from a nuclear gauge down hole probe. Once the source was removed from the probe, it was immediately leak tested. Two leak tests were performed and both readings pegged at full scale on the licensee's GM Pancake Survey Meter. The area was immediately cleared and one individual (the person conducting the source removal) was found to have contamination on their hands at 6000 CPM and 3500 CPM on portions of their clothes. This person was immediately decontaminated and a follow-up urine bioassay revealed less than minimum detectable levels. No other employees were contaminated, and the source was secured, awaiting disposal via a radioactive waste broker. Additional surveys of the work area revealed areas that required decontamination. The area was secured from entry and is awaiting decontamination by an outside vendor."
