ABSTRACT:
A personal electromagnetic radiation monitor includes an electromagnetic radiation sensor assembly having a surface area sensor in the form of a conductive can-shaped or boss-like element. The surface area sensor detects the radial electric field component directly from the radiating antenna or a secondary radial field component created by the displacement current induced in the wearer of the personal monitor who is illuminated by the electromagnetic radiation. The radial field component is detected by a diode detector circuit and is provided to a comparator circuit which will trigger an alarm if the induced current exceeds a predetermined level.
