I've been a big fan of Samsung. We have a
number of Samsung appliances and other devices - and have never had
issues (until now). They seem to make high quality devices which are
reliable as well. However, the other day I realized our new
refrigerator was putting out RF radiation constantly!!!
You see, so many new appliances have WiFi
or "Smart" capability inside them - active straight from the factory -
and will fill your entire house with RF radiation pulses constantly -
24/7 - starting the moment you give them electricity. ZigBee is the
trade name for some of this technology - the "Internet of things" - and
the idea that everything including our fridge needs to be monitored and
controlled remotely via a wireless network. Crazy. As I told Samsung -
I just want it to keep my food cool.
I measured before, but assumed what I was
hearing was coming from outside. Boy, was I wrong! I should have
double-checked when measuring by taking a baseline reading (with the
refrigerator off) and then with it on, because that would have caught it
My mistake, and I am sharing it with you
so you don't make the same one. The easiest way to test ANY device you
suspect could be emitting is to shut it off - disconnect the power
completely (and if it has batteries those too - but most things don't) -
read with your meter, paying close attention to what is in the
background, then turn the device on and wait patiently to see if
anything new is added.
A meter with sound like the HF35C or Acoustimeter or Acousticom 2
is vital. Different devices have different signals, which sound
completely different on the meters with sound. See the video of my
fridge radiating below.
