| Title | Stuck Source |
| Event Description | The following information was provided by the Rhode Island Department of Radiological Health via email:
At 0006 EDT, on July 14th, 2025, an Electric Boat employee was attempting to retract an Ir-192 source of 19.5 Ci. The employee was only able to retract the source halfway back to the exposure device when the source would not move any further. The employee then cranked the source back out into the collimator to provide shielding. The employee then contacted their supervisor to report the emergency notification and follow the emergency procedures as required. The boundaries were verified to be less than 0.5 mR/hr at all boundaries. There were no un-monitored personnel in the area. Additional personnel were provided to maintain control of the area. The radiation safety officer (RSO) was contacted at 0013 and notified of the hung source. The RSO arrived on site at approximately 0043 to assess the incident and determine a corrective action on how to move forward. The RSO and the radiographer returned the radioactive source to the exposure device at approximately 0300. The highest dose received by any individual of the recovery team was 1 mrem. The source in the exposure device was secured and returned to storage. Rhode Island Event Report ID Number: Rhode Island-25-01 |
