On August 6, 2020, World Testing radiographers were radiographing at Matrix Drilling in Lewisburg, Tennessee. They were radiographing pipes and one of the pipes (weighing approximately 1000 pounds) rolled onto the guide tube, denting it. They could not crank the source back in. They called the RSO [(Radiation Safety Officer)]. The guide tube was curled and making it more difficult to get the source back into the camera. They pulled on the crank to straighten out the guide tube and with enough pressure they were able to get the source past the dent and back into the exposure device. They placed lead on the collimator for additional shielding while working with it. The camera was a Sentinel, Model 880D, Serial number D-1120. The [Ir-192] source serial number was 96522G, with an activity of 44Ci. The source was exposed for approximately 4 hours. All personnel involved were wearing dosimetry. There were no overexposures. | On August 6, 2020, World Testing radiographers were radiographing at Matrix Drilling in Lewisburg, Tennessee.
