1. Apparatus for sanitizing human footwear having an opening in which a person'"'"'s foot is inserted to put on the footwear, comprising:

  • a light source operable to receive power from a power source and to emit radiation in a wavelength range that sanitizes the footwear by inhibiting growth of or destroying microorganisms present in an interior region of the footwear;

    a support for the light source to set it in a sanitization position to direct the radiation to the interior region of the footwear; and

    a light block arranged to inhibit the radiation from harming an individual proximally located to the footwear during sanitization;

    safety switch circuitry operable to activate the light source to emit radiation and operatively associated with the power source to interrupt delivery of power to the light source upon anticipation of escape from the footwear of an excessive amount of radiation caused by failure of the light block to inhibit the radiation or dislodgment of the light source from the sanitization position; and

    an ambient light sensor configured for placement within the interior region of the footwear and operatively associated with the safety switch circuitry to detect a presence of light leakage into the interior region of the footwear and thereby cause nonactivation of the light source to inhibit radiation emission.
