Non-Intrusive Mercury Detection and Measurement

Description:

b.      Non-Intrusive Mercury Detection and Measurement

Elemental mercury was extensively used at the Y-12 National Security Complex during the Cold War effort. Losses of significant amounts of mercury to building piping, equipment, and actual building structures (walls and floors – steel, concrete, drywall, Transit [asbestos boards and piping], clay tiles, etc.) occurred. Four former-use large industrial production facilities and their ancillary facilities are contaminated or may be contaminated with elemental and other mercury species to differing concentrations. These facilities are up to four floors in height, with footprints of several hundred thousand square feet each, and miles of piping both inside and outside the facilities, some with holdup and/or decaying conditions present.

 

This subtopic is focused on identifying technologies that can be used to non-intrusively detect elemental mercury in building materials, piping, equipment, and waste containers that will facilitate its segregation and removal. The technologies should be capable of detecting mercury in structures, piping, and equipment constructed of various materials/metals of varying thicknesses in the presence of solid residue materials. Detection equipment must be portable and capable of measuring in all orientations. Real-time analysis and display are preferable, with quantification of sufficient accuracy for use in meeting waste acceptance criteria based on meeting land disposal restrictions for mercury. Mapping of results should be addressed as well.
