The following information was obtained fro … The following information was obtained from the State of Texas via email:</br>On September 18, 2014, the Agency (Texas Department of Health) was notified by the Licensee's Radiation Safety Officer (RSO) that two radiographers working at a field location may have received exposures in excess of the annual whole body exposure limit. The RSO stated two qualified radiographers were working at a temporary field site using an INC IR-100 exposure device containing a 55 curie iridium-192 source. One radiographer (RA) was performing the exposures and the other (RB) was developing the film. The RSO stated RA walked out of the darkroom and saw the camera setting on the truck's tailgate. The radiographer also observed the dose rate meter sitting on the truck's tailgate was reading pegged high. The radiographers picked up the crankout device and cranked the handle approximately one-half turn which locked the source in the fully shielded position. The RSO stated RA read their self-reading dosimeter (SRD) and it was off scale. The RSO stated RB was not wearing a SRD or OSL (optically stimulated luminescence) dosimeter. The RSO stated RB was wearing an alarming rate meter, but they are hard to hear and with the background noise of the generator they did not hear it alarming.</br>The RSO stated RB was five feet from the exposure device for about 20 minutes. The RSO stated the calculated dose to RB is 12.8 rem based on their current information. The RSO stated RA was near the camera for about 30 seconds and his dose was calculated to be 10.8 rem. Both radiographers' dosimeters have been sent to the licensee's processor for reading. The RSO stated they have not calculated the dose to RA's hand yet. The RSO stated they are reenacting the event on September 19, 2014, to help calculate the dose to both workers. The licensee has contracted a consultant (Bruce Bristow) to aid in the dose calculations. The RSO stated the cause for the high exposures was failure of RA to fully retract the source. The RSO stated the exposure device was working properly. No other individuals received any exposure due to this event.</br>Additional information will be provided as it is received in accordance with SA-300.</br>Texas Incident # I-9235dance with SA-300.
