| Title | Stuck Source |
| Event Description | The following information was received from the Texas Department of State Health Services (the Department) via email:
On March 2, 2023, a licensee notified the Department that they were unable to retract a 79.6 Ci iridium-192 source to a Delta 880 camera at a temporary job site on March 1, 2023. After an exposure, the cable was cranked in but would not lock. The technicians cranked the cable back to the collimator and called a radiation safety officer (RSO). The RSO arrived at the site and found that both technicians had extended the boundary to 1-1.5 mR/hr. He then checked the dosimetry for both technicians and found both had received about 20 mR. The RSO investigated the source and determined that it had become disconnected from the wire at the point where the wire connects to the pig tail. The source was determined to still be in the collimator. A lead blanket was then used to cover the collimator. The crank-out and guide tubes were then replaced. The end of the pig tail was slowly exposed so that the wire could be connected by hand. The source was then retracted successfully back into the camera. The RSO wore a direct reading dosimeter on his hand while doing this and reported that his hands received around 600 mR. His whole-body dosimeter measured around 400 mR. His badge has been sent in for analysis. The technicians and public did not receive additional dose from this incident. Texas Incident Number: I-9997 |
