An UV disinfection system (200) may feature a chamber (207) with internal spherical reflective surfaces (208) to evenly reflect UV radiation from all angles to direct the UV radiation to all surface area of the object inside the chamber to disinfect object utilizing UV radiation under controlled time. An object (215) to be disinfected may reside within the chamber (207) on a UV transparent rack or shelf (214). The spherical reflective surfaces may be fashioned by placing such surfaces on a polyhedral internal structure or making the internal chamber spherical in and of itself (208). Multiple UV sources (209a), (209b) may also be utilized.
