1. A method for decontaminating a surface, the method comprising:
providing an aqueous-based oxidizer solution;
activating the aqueous-based oxidizer solution with an activator comprising at least one of a catalyst or UV photons near the surface to be decontaminated, wherein the activated aqueous-based oxidizer solution comprises a peroxyacid mixture comprising at least one of a persulfate, a peroxycarboxylic acid, or a hydrogen peroxide and the activator includes a stream of ozone containing gas and a ratio of a volume of ozone-containing gas to a volume of the peroxyacid mixture is between 500:1 and 0.1:1; and
applying the activated aqueous-based oxidizer solution to the surface to be decontaminated.
