Real-Time Remediation Utilizing The Backpack Sodium Iodide System And The U.S. EPA Triad Approach
Real-time characterization during remediation activities is being accomplished at the Idaho National Laboratory (INL) with the use of the backpack sodium iodide system (BaSIS). The BaSIS is comprised of a 3-in. by 5-in. sodium iodide (NaI) detector, differential corrected global positioning system (GPS), and portable computer, integrated into a lightweight backpack deployment platform. The system is operated with specialized software that allows the operator and/or remediation field manager to view data as they are collected. Upon completion of planned excavation stages, the area is surveyed for residual radiological contamination. After data collection is complete, data is available to the remediation field manager as a contour map showing the area(s) that require further excavation. The use of real-time measurement systems, rapid turn-around time of data, and dynamic work strategy support the U.S. Environmental Protection Agency’s (EPA) Triad approach. Decisions are made in real-time as to the need for further remediation. This paper describes the BaSIS system calibration, testing and use, and outlines negotiations with the appropriate CERCLA regulatory agencies (U.S. Environmental Protection Agency, Idaho Department of Environmental Quality, and U.S. Department of Energy Idaho Operations Office) to allow the use of real-time instrumentation during the remediation process, and for confirmation surveys. By using the BaSIS in such a manner, the INL seeks to demonstrate compliance with remediation objectives.
