the decontaminant processing section comprising a power generator and a decontaminant generator, the power generator being adapted for providing power for the decontaminant generator, the decontaminant generator being adapted for destroying residual amounts of decontaminant in the gaseous air stream, dehumidifying the gaseous air stream, and adding decontaminant to the gaseous air stream to form the decontaminant air stream.
a housing containing a decontamination chamber and a decontaminant processing section;
the decontamination chamber comprising a first entrance with a first door, the first entrance being adapted for placing articles to be decontaminated in the decontamination chamber, and an opposite second entrance with a second door, the second entrance being adapted for removing decontaminated articles from the decontamination chamber, the decontamination chamber including at least one gas inlet for admitting a decontaminant air stream into the decontamination chamber and at least one gas outlet for permitting a gaseous air stream to flow out of the decontamination chamber;
the decontaminant processing section comprising a power generator and a decontaminant generator, the power generator being adapted for providing power for the decontaminant generator, the decontaminant generator being adapted for destroying residual amounts of decontaminant in the gaseous air stream, dehumidifying the gaseous air stream, and adding decontaminant to the gaseous air stream to form the decontaminant air stream.
2. The decontamination unit of claim 1 wherein the decontamination chamber is adapted to permit a loading cart to enter the decontamination chamber through the first entrance, to be housed within the decontamination chamber, and to be removed from the decontamination chamber through the second entrance.
