1. A method for decontaminating a region with a vaporized decontaminant, the method comprising the steps of:

  • establishing a first concentration level of the vaporized decontaminant and a first exposure time associate with the first concentration level;

    injecting the vaporized decontaminant into the region at an injection rate for obtaining the first concentration level of the vaporized decontaminant in the region;

    monitoring the actual concentration of the vaporized decontaminant in the region;

    determining the dew point concentration of the vaporized decontaminant in the region;

    determining a dew point margin indicative of whether the actual concentration of the vaporized decontaminant in the region is at least a predetermined amount below the dew point concentration of the vaporized decontaminant in the region; and

    modifying the injection rate if the actual concentration of the vaporized decontaminant in the region is not at least the predetermined amount below the dew point concentration of the vaporized decontaminant in the region.
