A while ago I posted a comment in this article. The source of my concern was due that I was feeling uncomfortable each time I had to use a Panasonic NR-BT51 refrigerator which was bought for my home. In the comment I explained that such device claimed to come with different capabilities such as an energy saving motor, compressor, sensors for food, intermitting leds and an antibacteria silver filter or something. Other than this the device did not seemed to come with a Wifi capability so I thought that there shouldn’t be any concern or worry.
Because I did just found this wonderful site and the video explaining comparisons between older fridges and newer ones I became worried that my unit could be emitting some harmful RF or EMF which could be making me feel uncomfortable. However I do not have an acoustimeter or any other tool to test if my frigde was causing this.
One major concern about this was that I read that microwaves can cause health problems in the eyes, more specifically linking it to catarachts and perhaps other illnesses in the brain and other soft tissues. This was also triggered by the fact that I had a surgery done in my eyes as well years ago and I didn’t wanted to mess with it.
Anyways, the only response I got was that indeed there are studies which say about microwaves causing catarachts, however I was also curious if they could also cause damage in the retina, cornea and other structures in the eye. Unsure if there are studies or papers regarding this.
So far the only meter which I could find that could detect different kinds of RF was Extech model 480836, but I don’t know if anyone has used it?. In my comments I also made a question which so far has been unattended and that is. Does it exist any “safe level” of exposure from one which can say that no harm will happen? and for how long does someone has to be exposed to microwaves to begin noticing changes or having actual damage in its own body?.
I was told that the “AM radio” trick which is seen in different youtube videos doesn’t exactly meassure microwaves but dirty electricity. Could it be that this is what is making me feel uncomfortable?. I highly doubt this as it seems that the source of my concern is due each time I went closer to the fridge I felt being zapped by some radiation near the door as well as headaches. Although an answer has told me that “safe” values aren’t well defined and a bit complex. I’d like to know more about it. How does exactly is different microwaves in the 2.4 Ghz band used in Wifi and microwave ovens? to what can someone find in other devices such as refrigerators?.

AS you have probably found from the main site, there are 3 general areas to look at. 1. Power frequency electric/magnetic fields (50/60Hz), 2. Radio Frequency (c 800MHz-8GHz) typically including phones, wifi, Smart appliances etc and 3. ‘intermediate’ or Dirty Electricity frequencies, in the KHz range, which are carried on the mains electrical wiring.
With ref to a fridge – power frequency fields would come from the electrical wiring/motors/lights etc. You should only have a magnetic field when current is flowing – ie when the motor is running or if a light is on etc. Any electric field would normally decrease very quickly as you move away from the actual source. Aluminium foil should help to shield these fields provided it is grounded (I think – check on the main site). Magnetic fields are virtually impossible to screen. Presence of these fields is normally detected with a power frequency meter. There are several which cover both magnetic and electric fields (eg from Gigahertz and EMFields). If the fridge is not described as a ‘smart’ appliance it is unlikely to be emitting microwaves. If it is, foil shielding again should help to reduce them. Again, a meter would confirm. Dirty electricity might be produced by a variable-speed motor but otherwise I would not expect a fridge to produce DE. It is DE that the AM radio trick detects. There is no substitute for measuring these fields with a meter, so you know exactly what you are dealing with, and can check whether any screening has been effective.See the main site for recommended meters.
Regarding ‘safe’ levels, the ref document I use is this – https://www.ignir.org/Guidelines However I’m not aware that anyone has definitively stated that these levels are ‘safe’ (whatever that means) – for instance Trevor Marshall is finding effects at levels several orders of magnitude below what most scientists are looking at. In general one tries to reduce field levels as much as is reasonably possible.
Wifi vs ovens. Wifi and other similar signals are pulsed and polarised, which makes them much more bio-active. I’m not aware that microwave ovens share these characteristics. The fields from the oven are much stronger and the screening in the ovens does not protect completely from exposure.
There is more information on the main site here on all of these topics, including measurement and screening.
