Title: Method for radionuclide contaminatecontaminant mitigation

Patent ·
OSTI ID:1502363

The method and system disclosed provides radionuclide contamination mitigation by applying an aqueous carrier solution comprising a cation to a surface bearing a radionuclide contaminant to cause the radionuclide contaminant to enter solution forming a laden solution, then contacting the laden solution with a sequestering agent to bind to the radionuclide contaminant to form a laden sequestering agent. The removal and sequestration of the radionuclide contaminant from the contaminated surface leads directly to a reduction in the amount of radiologically-impacted critical infrastructure and the environment. The method and system are able to be performed or utilized economically with materials quickly available in the event of a radiological dispersion event.
