Abstract: A decontamination apparatus includes a housing defining an interior volume and having at least a top, a bottom, a left side, a right side, a front, and a rear. The top, the bottom, the left and right sides can each have a set of low-voltage UV-C light emitting diodes that face towards the interior volume. The front can include a front opening and the rear can include a rear opening. The apparatus can include a front door that is openable and closable to block the front opening, and a rear door that is openable and closable to block the rear opening, to allow objects to pass through the interior volume from the front to the rear. Alternatively, a belt conveyor system can pass through the interior volume from outboard of the front opening to outboard of the rear opening to allow objects to be conveyed through the interior volume.
