AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The following information was provided by the Arizona Department of Health Services (the Department) via email:
"The Department received notification from the licensee that a portable gauge was lost/stolen. A technician last saw the gauge on August 28, 2025, at 0130 MST at the technician's residence in Fountain Hills, Arizona. On September 3, 2025, the technician arrived at a jobsite at 1040 MST and realized that the gauge was not in the back of his truck. The gauge is a Troxler model 3411, S/N 17318, containing approximately 8 millicuries of cesium-137 and 40 millicuries of americium-241/beryllium. The Department has requested additional information and continues to investigate the event. The licensee has reported the gauge stolen with the city of Fountain Hills."
Arizona Incident Number: 25-017
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 - STUCK SHUTTER
The following information was provided by the Texas Department of State Health Services (the Department) via email:
"On September 4, 2025, the Department was notified by the licensee that the shutter on a Texas Nuclear model 5201 fixed source housing had failed in the open position during routine testing. This is the normal operating position for the shutter. The gauge contains a 100 millicurie (original activity) cesium 137 source. The licensee reported that there is no risk of additional radiation exposure to members of the general public or radiation workers. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - STUCK SHUTTER
The following information was provided by the Texas Department of State Health Services (the Agency) via email:
"On September 3, 2024, the Agency received notification from the licensee regarding a gauge with a stuck shutter. The gauge, a Ronan model SA1-F37, containing a 40 millicurie cesium-137 sealed source, is reportedly stuck in the open position. Open is the normal operating position. The licensee discovered the gauge failure during a routine planned maintenance exercise. According to the licensee, there is no risk of exposure to workers and members of the public. The licensee has contacted the manufacturer to repair the gauge.
"Additional information will be provided in accordance with SA 300 reporting requirements."

EN Revision Text: AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following information was provided by the Louisiana Radiation Protection Division (LDEQ) via email:
"On September 3, 2025, at approximately 1605 CDT, the radiation safety officer (RSO) for the licensee, Raba Kistner, Inc., notified LDEQ concerning an incident in which a Troxler model 3430 soil moisture density gauge, S/N 28457, was rolled over by a bulldozer. The incident occurred at the University of Louisiana at Lafayette New Iberia Research Center at approximately 1515 CDT. The RSO reported that during a direct transmission density measurement, in which the source was submerged in approximately eight inches of soil, the gauge was run over by the bulldozer. The gauge source rod was tilted in the soil approximately 45 degrees from the normal. It could not be determined if the source rod was bent, and no attempt was made to retract the density source into the safe position. The gauge possessed two sealed sources, an 8 mCi Cs-137 source, S/N 750-2469, and a 40 mCi Am/Be-241 source, S/N 47-25460. Both sources are approximately 28 years old. The gauge operator is currently maintaining an exclusion area of approximately 30 feet in radius about the gauge, which had a housing that was partially broken apart during the rollover. No radiation surveys have yet been performed of the gauge or surrounding area. The gauge manufacturer was contacted at time of reporting. The RSO will notify the LDEQ of incident status changes."

AGREEMENT STATE REPORT - MEDICAL EVENT
The following is a summary of information received from the Alabama Office of Radiation Control (the Agency) via email:
On September 3, 2025, an administering physician encountered resistance while delivering a dose of Y-90 Theraspheres. The patient received 67.2 mCi of a prescribed 90.7 mCi (24.4 percent underdose). The delivery apparatus was placed in storage to decay. Once decayed, it will be sent to the manufacturer (Boston Scientific) for evaluation. The patient was informed and advised that the delivered dose is acceptable therapeutically.
The Agency was informed of this incident on September 18, 2025, and will provide additional information as the investigation continues.
