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."

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."
