| Title | Unable to Retract Source |
| Event Description | The following is a summary of information provided by Protect, LLC via phone:
At 1043 CDT on 3/21/2025, the radiography crew was unable to retract the source for a radiography camera while performing work at a customer's manufacturing facility in Joplin, MO. The crew went to retract the source into the radiography camera, but the source did not move. The crew established boundaries to limit exposure to less than 2 millirem/hr. The crew notified site personnel and is monitoring the posted boundaries until the source is secured. Additional licensee personnel are enroute to retrieve the source. No personnel exposures due to the malfunction have occurred. Additional information: Manufacturer and model number: QSA Global 880 Serial number: A424-9 Source: Ir-192 Activity: 13 Ci
The following information was provided by Protect, LLC via email: On 3/21/2025, Protect, LLC had an industrial radiography source disconnect incident occur while at a customer's manufacturing facility in Joplin, MO. At approximately 1043 CDT, during the crew's first source retraction, it was determined that the source had become disconnected from the drive cable. The crew immediately recognized the situation through the use of their dosimetry equipment and established the emergency 2 millirem/hr boundaries. The regional radiation safety officer (RRSO) was immediately notified of the issue. The RRSO informed the crew to maintain surveillance of the restricted area barricades and to wait until the RRSO and corporate radiation safety officer (CRSO) arrived before any further actions were taken. The CRSO and RRSO arrived at the jobsite at approximately 1340 CDT to retrieve the source. The source was secured back into the exposure device at 1404 CDT. The CRSO received 4.5 millirem during the retrieval procedure and the RRSO received 0.6 millirem. Additional information on the manufacturer and model number of equipment involved in the incident: QSA Global 880 delta exposure device QSA Global Ir-192 source (13 curies), model A424-9 QSA Global 35 ft control cables QSA Global 7 ft extreme weather source tube with a 4 half-value layer (HVL) collimator All three personnel on the job are carded radiographers. Notified R3DO (Havertape) and NMSS Events Notifications (email)
The following is a summary of information provided by Protect, LLC via email: A thorough inspection of the exposure device, source pig tail and associated equipment was performed. The crank assembly failed the misconnect test but passed all of the no-go gauge checks. The extreme weather source tube showed minimal signs of wear with a slight bend on the end swaged connection. It is not exactly clear if the disconnect was caused by an operator error when the drive cable was connected to the exposure device or if somehow the source was able to become disconnected in the source tube while retracting the source back to the camera. As a precautionary measure the associated equipment was taken out of service. A corrective action report was issued related to this incident. Notifications to all employees will be conducted in a mandatory in-person attendance safety stand down and will be documented. Safety stand downs and re-training will be completed by April 18, 2025. Notified R3DO (Hills), NMSS Events Notifications (email). |
