Texas Department of State Health Services (the Department) via email:
On July 1, 2025, the Department received a notification from the licensee regarding a mechanical failure involving a level/density measurement gauge. The licensee reported that the failure was discovered on June 30, 2025. The affected gauge is a Berthold model LB 300 IRL Type I, containing a 500 millicurie cesium-137 sealed source. According to the licensee, the failure occurred when the cable connected to the source carrier broke, causing the source to become lodged within the thermowell inside the process vessel. The licensee stated that the vessel contains product, which is effectively shielding the source and limiting radiation levels outside the vessel. The licensee added that radiation surveys conducted on the vessel exterior indicated exposure levels of less than 2 milliroentgens per hour (mR/hr). There is no indication of elevated radiation risk to workers or members of the public. The licensee further stated that Berthold is scheduled to retrieve the source and repair the cable on July 2, 2025. Additional information will be provided in accordance with SA 300 Reporting requirements.
