The following information was provided by the
Texas Department of State Health Services (the Agency) via email:
On October 29, 2025, the Agency received a notification from the licensee regarding a source disconnect that occurred during an industrial radiography operation at a temporary job site. The radiography camera involved is a QSA Global Delta 880 model, containing a 102 curie iridium-192 sealed source (original activity date October 16, 2025). The licensee stated that on October 28, 2025, the guide tube through which the radioactive source travels became crimped, resulting in the source becoming stuck in the exposed position and preventing normal retraction into the shielded position. The licensee stated that a technician crimped the source tube by placing it through a swivel mechanism equipped with pressure clamps, rather than using a separate rod and properly attaching the source tube to the rod. The clamping pressure deformed the guide tube, causing the drive cable to fail when excessive force was applied by the technician to retract the source. The technician contacted one of the licensee's authorized source recovery experts who responded to the site. The licensee stated that the source was safely recovered and returned to the locked, shielded position using an empty camera for transfer. The source is currently stored at the licensee's workshop. The licensee stated that dosimetry badges for all workers present at the time of the incident have been sent out for processing to the service provider. The licensee stated that there was no exposure to members of the public as a result of this event.
Additional information will be provided in accordance with SA-300 reporting requirements.
