The agreement State of California reported … The agreement State of California reported the following via email:</br>On 06/13/12, the RSO at Team Industrial contacted RHB to report a radiography camera incident that occurred on 05/22/12 at the Evergreen refinery in Newalk, CA. The radiographers were using a QSA 880 camera on the second deck of the unit 1 at this refinery. The radiographer cranked the 59 Ci source out into the collimator and after the exposure, he couldn't retrieve the source back into the shielded position. He immediately contacted the RSO. Per RSO's instructions, the radiographer unscrewed the crank assembly and pulled the cable back to retrieve the source into shielded position. There were no exposures to the radiographers, two assistants, and any member of the public. The licensee's Instadose dosimetry indicated 8 mR for the radiographer for the period of 5/18 - 5/22 and 7 mR and 0 mR for the two assistants for the same period. Their pocket dosimeters indicated zero exposure for all three individuals.</br>The crank assembly was sent to QSA and they have indicted that the worn out teeth and bearings of the crank assembly inhibited the normal retrieval of the source.</br>RSO will be providing a detailed report to RHB ASAP.</br>CA 5010 Number: 061312</br>Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
