Ultraviolet-based detection and sterilization

A system comprising:

• a protective suit worn by a user, wherein the protective suit completely isolates the user from exposure to contaminants in an environment;
• and
• a disinfection chamber for sterilizing an exterior surface of the protective suit, the disinfection chamber comprising:
• a plurality of ultraviolet sources configured to irradiate the protective suit from a plurality of directions, wherein at least one of the plurality of ultraviolet sources emits UV-C electromagnetic radiation and at least one of the plurality of ultraviolet sources emits ultraviolet radiation configured to induce fluorescence in a target contaminant;
• a set of visible light sources configured to irradiate the object with visible light from a set of directions;
• and
• a set of cameras configured to acquire image data of the protective suit from a plurality of directions;
• and
• a computer system including a set of computing devices, wherein the computer system is configured to perform a sterilization procedure for the protective suit, wherein the sterilization procedure includes operating the plurality of ultraviolet sources and the set of visible light sources using the image data to evaluate shadow data to ensure that the plurality of ultraviolet sources deliver a dose of ultraviolet radiation onto the exterior surface of the protective suit sufficient to result in at least a log reduction of the target contaminant.

A system including:

• a handheld ultraviolet unit configured to induce fluorescence in a target contaminant on an adjacent surface, detect the fluorescence on the adjacent surface, and provide location data regarding a location of the fluorescence for processing by an external computer system;
• a disinfection chamber comprising:
• a plurality of ultraviolet sources configured to irradiate an object located within the disinfection chamber from a plurality of directions, wherein at least one of the plurality of ultraviolet sources emits UV-C electromagnetic radiation;
• a set of visible light sources configured to irradiate the object with visible light from a set of directions;
• and
• a set of cameras configured to acquire image data of the object from a plurality of directions;
• and
• a computer system including a set of computing devices, wherein the computer system is configured to perform a sterilization procedure for the object, wherein the sterilization procedure includes adjusting operation of the set of ultraviolet sources based on the location data and the image data to deliver a dose of ultraviolet radiation onto an exterior surface of the object to result in at least a log reduction of the target contaminant.
