ABSTRACT:
A new process is provided which when used will shield occupants of any dwelling from EMF radiation. The conditions specify the use of a conductive material which resists the passage of electric charge in a very narrow range, from 0.2-400 ohms/square with 377 ohms/square as best. This number has a special significance: it is the resistance of a perfect absorber of electromagnetic radiation. The coating will be used as a primer paint and will provide an excellent shield from EMF radiation, especially that which occurs with high voltage lines at 60 Hz but also for microwave radiation at a frequency of 10 kilohertz to 100 gigahertz.
