The following information was obtained from the State of
Oklahoma via email:
On August 27, 2018 [Oklahoma Department of Environmental Quality (DEQ)] were informed of an incident which occurred approximately 2140 CDT on August 24, 2018 involving 3 radiographers working for IRISNDT (OK-30246-02). The crew was working at a fabrication shop in Port of Catoosa, OK using a 95 curie Ir-192 source. The crew consisted of one certified radiographer, one radiographer trainer, and one assistant radiographer. The radiographer approached the collimator and knelt down over the guide tube. The assistant and the instructor unlocked the camera and walked back to the crank. Looking back at the camera, they did not see the radiographer and assumed he had already left the area. They began to crank out the source when the radiographer yelled and ran from the area. A re-enactment of the event using a pocket dosimeter recorded a dose of 62.1 mR, the direct reading dosimeter worn by the radiographer recorded a dose of 6 mR, probably due to shielding by the radiographers body. The whole-body badge reported a dose of 211 mR for the current month. A review of the daily exposure records for this monitoring period showed that the individual should have received approximately 155 mR previously, so the dose recorded for this incident is approximately 56 mR. Immediately after the incident the radiographer began complaining of a burning sensation and inflammation of his right shin area. [Oklahoma DEQ] are arranging with a local hospital to have him seen by a radiation oncologist. [Oklahoma DEQ] will conduct a reactive inspection of the licensee.

The following was received via email from the State of Oklahoma via email:
After the reactive inspection yesterday, [Oklahoma Department of Environmental Quality] has determined that the injury reported by the radiographer was due to his hitting his shin on a stand as he ran from the area. It does not appear that this incident resulted in an over-exposure to anyone.
