This disclosure includes a description of a sanitizing system for sanitizing a mobile electronic device comprising: a housing; a sanitizer contained within the housing configured to emit radiation with a sanitizing effect; and an entry system with a default closed position, the entry system being configured to permit a mobile electronic device to pass through the entry system and then automatically return to the default closed position, the entry system comprising a first outer enclosure and a second inner obstruction; wherein the entry system blocks radiation emitted within the sanitizing system to a level acceptable for consumer use, or wherein the second inner obstruction provides more radiation attenuation than the first outer enclosure, and/or wherein the combination of the first outer enclosure and the second inner obstruction provides more radiation attenuation than the first outer enclosure by itself. Disclosed are internal reflectors to help distribute sanitizing radiation generally evenly.
