The above chart is representative of the potentially harmful radiation emitted by smart meters. The peak RF values of 6-independent "real world" Itron Model: CL200 Electric Smart Meter Installations were evaluated over 5-minute periods using a Microsystem, Inc., Cornet Model: MD18, RF Field Strength Power Meter. The results were averaged. Individual result may very based on the type and model of smart meter and variables in the surrounding environment.
Smart meter enclosures are made of grounded metal on all sides except for the front glass (or plastic) globe. This metal enclosure acts as a RF and EMF shield and reflects the majority of radiation through the front globe. The front glass or plastic globe of a smart meter is where the majority of RF radiation is emitted (in all directions). A properly installed RF Meter Shield completes a shield around the entire smart meter (reducing radiation by over 80%). A minimal amount of RF and EMF radiation may still escapes through main feed wires to and from the meter. Since every installation is unique, after installing a RF Meter Shield, if you have concerns regarding smart meter radiation entering your home, we suggest you have your unique installation tested.
Shield Efficiency
Attenuation is one of the principal indicators for measuring the effectiveness of electromagnetic interference shielding. It refers to the difference between an shielding and its intensity after shielding. Attenuation is marked in decibels (dB) that correspond to the ratio between field strength with and without the presence of a protective medium. The decrease in a signal’s intensity, or amplitude, is usually exponential with distance, while the decibel range falls along a logarithmic scale. This means that an attenuation rating of 50 dB indicates a shielding strength ten times that of 40 dB. In general, a shielding range of 10 to 30 dB provides the lowest effective level of shielding, while anything below that range can be considered little or no shielding. Shielding between 60 and 90 dB may be considered a high level of protection, while 90 to 120 dB is exceptional.
