A practical, germicidal, personal protection system may be worn by a user to kill or deactivate germs, viruses or other pathogens, which are located in the air to be breathed by the user. Before entering a mask, a hood or a suit worn by the user, air is exposed, in a sterilization unit, to Ultra-Violet C-band (UVC) radiation. Advantageously, the UVC radiation is lethal to undesirable germs, viruses and other pathogens. In this manner, pathogen-free air may be provided to the user. Bulbs used to generate UVC radiation are known to also promote the creation of ozone. Accordingly, the personal protection system includes means to minimize the ozone in the air that ultimately reaches the user. A similar personal protection system may also be used expose, to UVC radiation, breath exhaled from the user, thereby killing any germs, viruses or other pathogens exhaled by the user.
