| Title | Radiography Source Disconnection |
| Event Description | The following report was received by the Texas Department of State Health Services [the Department] via email:
On July 16, 2023, the Department was notified of an industrial radiography source that was discovered to be not connected on July 15, 2023. The licensee reported that the camera was a QSA Delta 880 with serial number D11651 which contained a 31.5 curie Ir-192 source with serial number 72211M. The radiography crew had completed their first exposure and tried to crank the source back in, but it would not lock. After several more tries, they reported the incident to their site radiation safety officer (RSO). The RSO instructed them to expand the barrier and maintain constant surveillance. When the RSO arrived, he checked the dosimetry of the two radiographers and found they were both around 1 mR. He tried cranking the source back in and found that it would not lock. He also found that the survey meter readings were not changing so he concluded the source was not connected. Using 6 foot tongs, he was able to manipulate the guide tube and get the source to drop out. He then covered the source with about 150 pounds of lead such that the exposure rate was down to 30 mR/hr. He then connected the source to the drive cable and cranked it back into the locked position. The RSO received about 14 mR to both hands and whole body. Another worker who assisted with the lead received about 10 mR to the whole body. Badges have been sent in for processing. Further information will be provided per SA-300.
