1. A disinfection system, comprising:
a first Ultraviolet-C (“UVC”) radiation source;
a second UVC radiation source opposing the first UVC radiation source positioned such that a gap exists between the first UVC radiation source and the second UVC radiation source, wherein the first UVC radiation source is configured to emit UVC radiation across the gap toward the second UVC radiation source and the second UVC radiation source is configured to emit UVC radiation across the gap toward the first UVC radiation source;
a vertically-oriented conveyor system partially positioned in the gap, the vertically-oriented conveyor system comprising:
at least one vertical band; and
a motor configured to translate the at least one vertical band through the gap between the first UVC radiation source and the second UVC radiation source; and
wherein the at least one vertical band is configured to have at least one medical garb mounted to it such that when the at least one vertical band is translated through the gap an outer surface of the at least one medical garb is exposed to UVC radiation emitted from the first UVC radiation source and an inner surface of the at least one medical garb is exposed to UVC radiation emitted from the second UVC radiation source.
