Abstract: Described herein are methods and systems for decontaminating surfaces on aircraft from pathogens using UV lights with wavelengths between about 200 nanometers and about 240 nanometers. These wavelengths are able to effectively decontaminate pathogens while remaining safe to humans. In other words, humans can remain in decontamination zones during operation of these systems. Furthermore, UV transparent apparatuses, such as door handles, allow decontamination of all surfaces of these apparatuses whether these surfaces are directly or indirectly exposed to the UV light. The indirect exposure is provided by the UV lights passing through the apparatus. Therefore, even surfaces without a line of sight to UV light sources are decontaminated. As such, these methods and systems allow to achieve effective decontamination of an apparatus with a complex surface (e,g., a door handle) without requiring many UV light sources positioned around this apparatus.
