The following report was received from the
Texas Department of State Health Services, Radiation Branch, via e-mail:
On October 23, 2013, the licensee notified the Agency [Texas Department of Health] that one of its radiography crews had been unable to retract an iridium-192 source back into a QSA 880D exposure device at a temporary work site in Baytown, Texas. Following an exposure, the source pigtail would not retract fully into the device. An authorized person, the Radiation Safety Officer (RSO), performed the source retrieval. He received an estimated 600 millirem dose. No member of the public received any exposure as a result of this event. The RSO reported that he had to disconnect the crank handle from the drive cables to pull the source back into the camera. The cause was an equipment failure of the drive cable which was binding. A new set of drive cables was attached to the camera and the source moved in and out freely about 10 times. The drive cables were only 3 weeks old. They will be returned to the manufacturer for inspection. An investigation into this event is ongoing. Information will be provided as it is obtained in accordance with SA-300.
Camera and source information: QSA 880D camera, serial number D4621, source model number 424-9, source serial number 98960B.
Texas Incident Number: I-9130
