High magnetic field in bathrooms caused by refrigerators

I decided to do a recording today showing how the RF radiation would be lower in one of my bathrooms, which is more distant from a wi-fi router, and also separated by thicker walls. I thought it was interesting to record this since I decided to not use anymore the bathroom close to the router.

This I already expected to be different (RF radiation levels), however I discovered something else today.

- There are 2 refrigerators here;

- The second bathroom is separated by a wall/corridor from the smaller fridge (for example).

The thing is:

- Both refrigerators are causing high magnetic fields in both bathrooms. The "disturbance" (I will call this way) is enough to increase the magnetic field in almost the ENTIRE BATHROOM.

Example:

- The bathroom from the corridor measures 4 mG in the sink. Once I turn on the microwave oven this may increase to 8 mG.

If the fridge is turned off internally the magnetic field is reduced to normal levels. I believe 0.1, 0.2 mG.

And the same thing is valid for the other (1-2 mG in the sink, 10 times lower when the magnetic field from the fridge is also lower).

Can this be fixed? And it is as I said in the video description a wiring error?

If this can be changed what would I need to do?

This is the video:

- Cornet ED88TPlus, Acoustimeter and UHS2 (Gaussmeter) - Measuring radiation levels from bathrooms

At first I thought there was a problem with the gaussmeter. But after further investigation I discovered the truth.

VIDEO DESCRIPTION
*********

Measured in this video (recorded in October 24, 2018):

- Two bathrooms from my apartment.

When my text refers to "1st" it means the bathroom that is located close to the wi-fi router; when it says "2nd" I mean the bathroom from the corridor, distant from it.

- Please note my wi-fi router (VR900) is turned on during this recording, as I said before very close to the 1st bathroom. The 2nd bathroom is not only a few meters distant, it has walls blocking (not 100%, of course) the wi-fi signal from reaching it, so it receives less RF radiation because it has been weakened.

I am using the following settngs in the router:

- Beacon interval: changed to 1000 instead of the default 100;
- Transmit Power (2.4 and 5 GHz) changed to Low instead of Middle/High.

This way the radiation levels measured in most locations of my house may not be the ideal ones , however aren't much high.

Notes: the Cornet ED88TPlus (EMF meter) is using (for readings) volts per meter (V/m). The UHS2 Gaussmeter is configured to the 1st position (3-AXIS ELF + VLF). This reads the 3-axis magnitude of the magnetic field in milliGauss.

- The video starts with the Cornet ED88TPlus meter measuring things, in the room where the router is. Seconds later I enter the 1st bathroom, separated from the router by a wall. Obviously close to the toilet, sink and shower the RF radiation is still high. What proves the point about distance being essential to receive less radiation, not just mere obstacles.

- 02:09 - Now we measure the magnetic field. Compared to other locations from my house these readings are high (the ideal is 0.5 mG or less).

- 05:12 - The Cornet from here on measures the 2nd bathroom, distant from the router. Notice how next to the sink, toilet and below the shower the RF radiation is much, much lower than before.

- 06:08 - The Cornet starts measuring in the same location the magnetic field. There are no changes at this point, and the levels are low. That happens  because the SMALLER refrigerator from the kitchen is what generates this type of "radiation", while the BIGGER fridge from one of my rooms (yes, I have two) is responsible for any increase in the 1st bathroom (since it's closer to it).

When the fridge turns itself off internally (somehow is in standby for a few minutes, and later continues to "work" again) it stops emiting a strong magnetic field. I believe due to some wiring error in my apartment (which is not uncommon and many houses, especially old ones, have this problem) this happens.

- 07:20 - See how the fridge located in the kitchen is not emiting the usual magnetic field levels. That explains the lower values for the 2nd bathroom.

- 08:36 - The UHS2 gaussmeter is turned on. In my bedroom it measures only 0.1 mG. Later I measure again the 2nd bathroom and confirm the previous Cornet readings.

- 10:05 - Back to the 1st bathroom we see the sink and below the shower the magnetic field is more or less 1-2 mG, which is considered high.

- 13:00 and after: 22:15 - 23:24 - 24:56 - A surprise: the 2nd bathroom for the first time register higher values: about 4 mG in the sink, and 0.5 in the toilet. Close to the shower the readings are still the same: 0.1 mG.

After 14:31 and 25:10 you'll see the SMALLER fridge is emiting the usual magnetic field: 1 or more mG when we approach the meter.

- 15:42 and after 19:20 - This time I use the Acoustimeter, which will check first the RF radiation from the 2nd bathroom. At 17:32 it register higher values in the bathroom close to the wi-fi router.

- 18:58 - The Acoustimeter is now in the bedroom where the Archer VR900 (wi-fi router) is.

- 19:45 - The situation from my bedroom in terms of RF radiation.

- 20:22 - The Cornet measures again the corridor bathroom, distant from the router. This time the magnetic field is HIGHER.

- 22:33 - The UHS2 informs the magnetic field from the 1st bathroom is insignificant in comparison to what was measured before. The reason for this can be seen after 23:52 - the BIGGER refrigerator (which is the closest appliance to this bathroom) is not emiting the same magnetic field we see everyday (it should say 1 or more miliGauss when the meter is close to it).

That means the fridge has turned itself off, internally, and temporarily.
