| ENS 52422 | 9 December 2016 14:00:00 | 10 CFR 30.50(b)(2) | Radiography Source Became Temporarily Stuck Outside of Shield | While preparing to perform his first exposure of the day, the radiographer determined that the source became stuck near the camera and guide tube connection. He notified the client, verified his boundaries, and contacted the Radiation Safety Officer (RSO). After discussion with the radiographer, the RSO believed the source was lodged due to freezing temperatures and a small amount of ice within the guide tube. The radiographer was able to obtain a heater and, after about an hour of warming the guide tube, was able to retrieve the source into the camera normally. No overexposures occurred due to this event. The camera is a SPEC-150 that contains 47 Ci of Ir-192. | ||
| ENS 51963 | 27 May 2016 04:00:00 | 10 CFR 30.50(b)(2) | Radiography Camera Source Unable to Be Retracted | Radiographers were performing an exposure when the guide tube disconnect failed and the guide tube disconnected from the camera. This prevents the source from being fully retracted into the camera. The division manager, trained in source retrieval, was able to get the source into the camera and into its shielded position. No overexposures occurred. The quick disconnect was replaced and tested and the camera was returned to service. The camera was a SPEC-150 using a 62 Ci Ir-192 source. | ||
| ENS 46192 | 20 August 2010 17:00:00 | 10 CFR 30.50(b)(2) | Damaged Radiography Camera Guide Tube Preventing Source Retraction | JANX crew was working on a piping fabrication. A piece of 2 inch pipe fell while making an exposure. It is believed that the falling pipe struck the guide tube. The radiographer then attempted to retrieve the source. The source partially retracted and then became stuck. The area was then cordoned off. The area is being well controlled. JANX's customer is Dominion Gas Transmission. There are no residential units close to this area. Source Production & Equipment Co. Inc. (SPEC) has been contacted. SPEC is dispatching personnel to effect source retrieval. No overexposures resulted from this event. The radiography camera is a SPEC model 150 containing 90 curies IR-192. GPS coordinates of event location: 39.10699 N 80.49879 W Notified R1DO (White) and FSME EO (Delligatti). | ||
| ENS 43845 | 14 December 2007 01:00:00 | 10 CFR 30.50(b)(2) | Safety Equipment Failure | In a remote area in Missouri, radiography personnel were x-raying welds on a pipe that was placed in a trench. Away from the radiographers, the pipeline contractors moved another pipe in the trench which caused the trench to collapse, allowing water into the trench. The radiography saw it happening and immediately cranked the source into the shielded position. The water submerged the SPEC-150 radiography camera and equipment. Using the same camera, the radiographer set up for a shot in a different location. When exposing the source, it became stuck in the unshielded position. The radiographer immediately notified the RSO and marked off the area with boundary tape while he awaited assistance from the vendor. When the vendor could not immediately respond due to weather related travel issues, the radiography personnel procured a heater to thaw the camera as they suspected the camera was frozen from the earlier water intrusion. Surrounding temperatures were in the twenties. After warming the camera, they were able to successfully retrieve the source to the shielded position. |
