The following report was received from the … The following report was received from the State of Louisiana via email:</br>Event Date and Time: 01/16/2015, around (1515 CST) a radiography crew was working at the ExxonMobil Refinery on Scenic Highway, Baton Rouge, LA. The event was reported (about 1645 CST) on January 17, 2015, by a phone call from (an individual) who represented himself as the Corporate RSO. He stated he drove down on January 17, to evaluate and investigate this incident. He reported this incident appears to be a Human Error Potential Excessive Exposure. </br>Event Location: ExxonMobil Refinery 4999 Scenic Highway. Baton Rouge, LA 70805. A temporary jobsite for Acuren Inspection.</br>Event type: This is a potential excessive exposure involving a radiographer attempting to breakdown a radiography exposure setup. He attempted to disconnect the guide tube from the exposure device and the source was not locked in the shielded position. It was noticed that the locking device was red after the guide tube was handled to disconnect it from the exposure device.</br>Notifications: LA DEQ (Department of Environmental Quality), Assessment, Radiation by direct phone call to our after hours answering system. The notification came in around (1645 CST) on January 17, 2015.</br>Event Description: The radiography crew was making exposures on lower level equipment at the ExxonMobil Refinery. The crew was utilizing (about) 38 Ci of Ir-192. The crew attempted to breakdown/disconnect the equipment after the exposures. The guide tube would not disconnect. The 2nd hand of the crew manipulated the drive cable that returned the source into the shielded position. A quarter turn on the crank shielded the source. </br>The radiographer and his equipment were checked. His pocket dosimeter was off scale, but he claims his Alarm Rate Alarm meter did not alarm. A second check of the Alarm Rate Meter revealed the unit did alarm, but it was a weak alarm.</br>Estimated dose calculations were done for his whole body and extremities. His whole-body estimated dose was 3.3 Rads and his extremity dose was estimated at 206 Rads to his hands. These were calculated on a one minute exposure where a .5 minute is more realistic. The exposed radiographer was taken to Core Occupational Medicine for examination, x-rays and blood work. He is being monitored and examined every other day. At this time he has been asymptomatic for an excessive radiation exposure. The Licensee is conducting reenactments.</br>This incident is not considered closed by the Department (LA DEQ). The investigation findings will be updated when they become available.</br>The equipment was all QSA equipment loaded with 38 Ci Ir-192. This appears to be an operator error exposure. </br>The source is secure from removal and unnecessary exposure. This event is not closed and additional investigation and evaluation will continue. The source is in a safe shielded position and no threat to workers or the general public.</br>Transport vehicle description : N/A This was at a temporary job site inside the ExxonMobil Refinery located in Baton Rouge, LA.</br>License Numbers: LA-7072-L01, AI 126755</br>Louisiana Event Number: LA1500002I 126755
