| Title | Agreement State Report - Radiographer Potential Overexposure |
| Event Description | The following information was received via fax:
On March 18, 2015, the Radiation Safety Officer for Vital Inspection Professionals, Alabaster, Alabama notified the Office of Radiation Control [for the State of Alabama] in regards to a potential overexposure which may have occurred while conducting radiography at the Alabama Power, Miller Steam Plant. On March 17, 2015 at approximately 2130 CDT, a crew was conducting radiography. The crew consisted of one radiographer and three assistants. They were completing two exposures lasting 35 seconds, and with a set-up time of approximately 15 to 18 minutes. After completing the two exposures, the radiographer noticed that his pocket dosimeter (200 mR) was off-scale. The first assistant's pocket dosimeter was reading 50 mR, the second assistant's pocket dosimeter was off scale and the third assistant was not wearing any dosimetry. The radiographer and first assistant acknowledged that their alarming rate meters were functioning correctly, the second assistant and third assistant were not wearing an alarming rate meter. The crew notified their Radiation Safety Officer at 2130 CDT, but did not contact him until around midnight. The crew immediately stopped work and was told to meet the Radiation Safety Officer the next morning to discuss the events. All available dosimetry was sent off for emergency processing and [dose information] should be received by noon, March 19, 2015. From the discussion it was determined that the survey meter had an apparent electrical short and was not measuring properly. The camera was checked and determined to be functioning properly. Based on the licensee's preliminary dose estimates it was determined that one crew member may have received up to 45 Rem whole body.
The following update was received from the Alabama Department of Public Health via fax: On March 25, 2015, Agency representatives visited Alabama Power Miller Steam Plant and met with representatives of the plant and reviewed the area where the incident took place.
