Provided is a decontamination apparatus for rendering an object pathogen reduced. The decontamination apparatus includes a frame to be positioned in suitable proximity to the object to enable the decontamination apparatus to perform a decontamination process that achieves at least a predetermined minimum level of pathogen reduction on the computer peripheral. A light source coupled to the frame to be transported along a decontamination path emits ultraviolet light suitable to deactivate at least a portion of a pathogen population on the computer peripheral. A shield interferes with transmission of the ultraviolet light in directions generally away from the computer peripheral, and a controller operates the light source and transports the light source along the decontamination path during the decontamination process.
