The following information was received from the state of
Texas via email:
On August 16, 2022, the licensee reported that they were unable to retract a radiography source into a Spec 150 Camera at approximately 1233 [CDT] at a temporary job site. The camera contained a 45 Curie
Iridium-192 source. The two radiographers reported the issue to the site Radiation Safety Officer (
RSO) and stepped back beyond the boundary. The site
RSO arrived within the hour.
Lead shielding was placed over the guide tube. The site
RSO got another licensee employee to assist and they straightened out a rigid guide tube which was attached to a flexible guide tube. They eventually added more
lead shielding and disconnected the rigid guide tube from the flexible guide tube. At that point the source retrieved freely into the camera. They believe a pebble which fell out of guide tube was blocking the source from moving. Both individuals were authorized to conduct source retrieval. The site
RSO received the highest dose of 30 mrem during the retrieval. Further information will be provided per SA-300.
