I discovered my new Samsung RS22HDHPNSR was radiating my family and me constantly. Despite the fact that we are NOT on a smart grid, no smart meters nearby, nor do we have a WiFi router and have not configured the refrigerator to connect to anything, it is still radiating.
Right out of the box many appliances radiate RF energy. You need a good RF meter like the HF35C or the Acoustimeter from ElectraHealth.com to check for this. More and more devices are using this and ZigBee technology – because someone thinks everything should be connectable – as if that is safe, healthy, secure, and private.
