A representative of the State of Nebraska … A representative of the State of Nebraska has received preliminary information about a radiography incident that may have resulted in overexposures. The incident occurred during radiography of elevated piping at a pumping station. The radiographer and a contactor operating an aerial lift bucket had just completed a radiography shot on some overhead piping. The assistant radiographer was in a different location and had supposedly retracted the source into its safe position. Because the radiographer had his alarming rate meter under his clothing, and because there was significant ambient noise in the work area, the radiographer did not immediately hear that his rate meter was alarming as he and the aerial lift operator approached the radiography camera guide tube to set up for the next shot. When the radiographer heard the alarm, he checked his pocket dosimeter and found it off-scale. The radiographer had the assistant re-perform the source retraction and was subsequently able to confirm that the source was now fully retracted into the camera's safe position.</br>Based on initial estimates by the radiographer, his worst case exposure could be as high as 7.1 REM. The best case scenario would put his exposure around 200 mREM. The aerial lift operator, who is not a radiation worker, is believed to have exposures less than the radiographer. The radiographer's TLD has been sent for immediate processing by Landauer.</br>The State should have an inspector at the site on 2/28/10. This report will be updated and more details provided after the State completes its initial inspection.he State completes its initial inspection. +
