Chemical decontamination
Chemical decontamination uses concentrated or dilute reagents in contact with the contaminated item, to dissolve the contamination layer covering the base metal and eventually part of the base metal.
Chemical decontamination of substance can be achieved through decomposition, neutralization, and physical processes, though a clear understanding of the underlying chemistry is required.
