1. A method for treating contaminated surfaces, the method including:
providing a mobile decontamination system disposed as a mobile cart for housing:
one or more on-board storage tanks for storing a directed energy enhancer (DEE) formulation in each tank;
a sprayer subsystem in fluid communication with the one or more on-board storage tanks;
a radio frequency subsystem including a microwave generator and a plurality of pyramidal horn antennas, wherein the orientation of the antennas is adjustable; and
a control system, wherein the one or more on-board tanks, the sprayer subsystem, the radio frequency subsystem, and the control system are housed in the mobile cart;
spraying the DEE formulation on to the contaminated surfaces disposed external to the mobile cart using the sprayer subsystem to substantially coat the contaminated surfaces to form coated surfaces;
waiting for a predetermined hold time; and
generating reactive oxidative species by decomposing the DEE formulation using microwave radiation directed from the microwave generator using the pyramidal horn antennas to the coated surfaces for a predetermined exposure time to substantially decontaminate the coated surfaces to yield treated surfaces.
