1. A system for irradiating an area with ultraviolet light, comprising:

  • a mobile housing;

    a receiver associated with the housing;

    at least one power source;

    at least one radiant-energy emitter for continuously emitting ultraviolet light during operation of the system for disinfection of the area, the at least one radiant-energy emitter associated with the housing and powered by the at least one power source, wherein ultraviolet light emitted from the at least one radiant-energy emitter is capable of being varied based on power received from the power source;

    at least one radiant-energy sensor assembly, the sensor assembly including a first radiant-energy sensor, a second radiant-energy sensor, and a transmitter, the at least one radiant-energy sensor assembly detecting an amount of ultraviolet light from the first and second radiant-energy sensors during operation of the system and transmitting information regarding the amount to the receiver;

    wherein the amount of ultraviolet light detected by the first radiant-energy sensor includes both ultraviolet light created by the at least one radiant-energy emitter that is received directly from the at least one radiant-energy emitter and ultraviolet light created by the at least one radiant-energy emitter that is received after reflection off items in the area; and

    wherein the amount of ultraviolet light detected by the second radiant-energy sensor includes ultraviolet light created by the at least one radiant-energy emitter that is received after reflection off items in the area, but does not include ultraviolet light received directly from the at least one radiant-energy emitter; and

    control logic configured to terminate the emitting of ultraviolet light by the at least one radiant-energy emitter based on the information transmitted from the transmitter to the receiver, wherein the information includes data relating to disinfection of the area.
