1. A method of providing an internal body temperature approximation of a human body, the method comprising:

  • measuring infrared radiation by scanning a thermopile radiation detector across a target surface of a forehead, wherein the target surface of the forehead is skin surface over the superficial temporal artery passing over the skull bone directly between the skin and the skull very close to the skin, the radiation detector providing an electrical output;

    determining a sensed skin surface temperature from the radiation;

    sensing ambient temperature to which the body is exposed; and

    in electronic circuitry, using the measured infrared radiation and the sensed ambient temperature to which the body is exposed, determining the internal body temperature approximation, the determined internal body temperature approximation comprising the sensed skin surface temperature plus an amount based on the sensed skin surface temperature and the sensed ambient temperature to which the body is exposed.
