| Title | Agreement State Report - Radiographer Unplanned Exposure |
| Event Description | The following report was received via e-mail:
On July 18, 2016, at approximately 1705 MT, the Colorado Department of Public Health and Environment received a call on its incident notification phone from the acting Radiation Safety Officer (RSO) for Mistras Group, Inc., (CO License CO 963-01). The acting RSO reported that while a Grand Junction, CO based crew was performing industrial radiography activities at a fabrication shop/area in Coburn, CO on June 18, 2016. A radiographer received an estimated whole body dose of approximately 500 mrem, and an estimated extremity dose of approximately 12 rem (12,000 mrem) due to the radiographer handling the guide tube while the source was still present in the guide tube. The source had reportedly become hung up in the guide tube, but at the time of the exposure the radiographer believed the source had been returned to the shielded position. The radiographer was not reportedly using a survey instrument at the time he approached the source just prior to the exposure event. The assistant radiographer remained near the source crank and did not have direct contact with the source containing guide tube. The assistant radiographer reportedly received approximately 20 mrem (whole body dose), based upon his pocket dosimeter reading. The source in use at the time of the incident was contained in a SPEC 150 imaging device with approximately 60 Ci of Iridium-192. Dosimeters for the radiographer and assistant radiographer have been submitted to the licensee dosimetry provider and results are pending. The radiographer has been restricted from further work involving radioactive materials until the licensee can complete an investigation. The guide tube equipment has been taken out of service and is being evaluated by the licensee for possible defects. |
