| Title | Radiography Camera Failure |
| Event Description | The following is a summary of information provided by Mistras via phone:
A Mistras two-person radiography crew was working at a customer site with a 61 Ci Ir-192 source from an elevated platform. The crew went to retract the source, but it did not move after several attempts. The crew then realized the source was disconnected from the drive cable. The crew expanded the radiography boundaries to limit exposure to 2 mR/hr. The crew notified site personnel and is monitoring the posted boundaries until the source is secured. Additional Mistras personnel are en-route to retrieve the source. No personnel exposures due to the malfunction have occurred.
The following is a summary of information provided by Mistras via phone: On October 2, 2024, at 0120 EDT, a repair crew arrived onsite to perform repairs to the radiography camera. The crew successfully repaired the device and retracted the source into the shielded position at approximately 0320 EDT. No personnel overexposures occurred due to the radiography camera failure. Notified the R4DO (Gepford) and NMSS Events Notifications via email. |
