| Title | Radiography Camera Source Fails to Completely Retract |
| Event Description | On November 10th, the radiography crew working the Kuparuk Oil Field on the North Slope of Alaska experienced a malfunctioning locking system on an INC IR-100 exposure device (serial number 6774).
During the shift, the source was cranked in and the camera was surveyed per the proper procedure. There were no abnormal readings observed during the survey and the key was turned to the lock position. When the crank assembly was removed it was noted that the pigtail was not fully seated. The 2 mR/hr boundary was reconfirmed and the Foreman and Supervisor were notified. The camera was surveyed and noted as being safe to transport. The camera was tagged out and placed in the Permanent Storage facility. A trained radiographer removed and cleaned the locking system. The locking system was successfully reinstalled. The camera has been returned to service. Exposure Device: Industrial Nuclear IR-100 Device S/N: 6774 Source S/N: 70129B Source Activity: 63.4 curies Source Type: Ir-192 Source Model # QSA 87703 There was no exposure to the crew or the general public during this incident.
