The following information was provided by the
Texas Department of State Health Services (the Agency) via phone and email:
On October 10, 2025, the Agency received a notification from the licensee regarding a failure of the shutter mechanism on a level measurement gauge. The gauge is a Vega Americas SHRM-B model, containing a 300 millicurie cesium-137 sealed source. The licensee stated that the roll pin, which attaches the shutter handle to the shutter shaft, had detached, resulting in the separation of the handle from the shaft. The shutter shaft connects the handle to the shutter allowing it to be opened or closed. The shutter is currently stuck in the open position, which is the normal operating position. The licensee stated that there is no risk of additional radiation exposure to members of the public or radiation workers due to this mechanism failure. The licensee has notified a licensed service provider to repair the unit. Additional information will be provided in accordance with SA-300 reporting requirements.
