Abstract: Decontamination is achieved by practicing a method using the disclosed apparatus for producing a magnetically energized, excited decontamination aerosol 26. The apparatus has a source of decontamination fluid 10 and an aerosol producer 12 that operates at substantially one atmosphere ambient pressure. A magnetic energizer 20 modifies the energy state of the aerosol 14 which then passes through a charging ring 24. The further modified, excited droplets 26 then permeate a location or contact an object 28 to be decontaminated.
