At a distance of 1 m from the meter, the power density is 55 microwatts/m2. With regard to the strength or intensity of the magnetic and electric fields, you will find that type of technical information in the following documents: intensity of the magnetic field, intensity of the electric field.[In French only]
The emission rates of next-generation meters are far lower than those of most home electronics, like cell phones, microwave ovens, etc. For more information, see the following table: Comparison of RF Emission Levels.
