EMF (electromagnetic fields) emissions from Tesla batteries, compared to other cars

I really love the Tesla Model Y. I want that car!

We've tested the Mini Countryman SE, Toyota bZ4X, Mercedes EQA, KIA Niro EV, Volvo XC40, Tesla Model 3 and Y.
By far, the Tesla (Model Y) stands out as the best. Period.

However, the amount of EMF (electromagnetic fields) emitted by Tesla cars (specifically the Model 3 and Y) is WAY higher than all the other vehicles.

We used an EMF meter and checked the readings for both the "Standard" and "Weighted" measurements, focusing mainly on the areas around the footwells.

All the other cars had totally acceptable levels (< 5 mG **), while the Tesla, even when stationary, registered between 30-80 mG, particularly in the right-side footwell (both in the front and rear seats). When I accelerate, the meter spikes, even on the left-side footwell.

I bought a Faraday EMF blocking sheet, from Amazon, to test.

We tried it on our home wifi router — without fully wrapping it, just covering the sides — and it completely blocked the EMFs between the router and the meter.

But when we placed the blanket on the footwell of the Tesla, the readings didn't change. It's likely that the EMFs are going around the blanket somehow. :(

It's really frustrating... and because of this, we're likely not to get the car anymore.

Please let me know if you have any ideas I can try, to "fix/alleviate" the EMFs exposure in the car.

Before you reply with a non-constructive answer or by making fun:

1) Yes, I am already aware that devices like the fridge, phone, microwave, etc., emit radiation.
However, I'm not sitting next to these devices continuously for hours.
I don't own a microwave, I always use the speaker when talking on the phone, and I don't keep the phone in my pocket. (And yes, I'm 100% happy living this way.)

2) I understand that Tesla may comply with regulations and that the cars wouldn't be allowed if they exceeded a certain radiation threshold.
However, tobacco and junk food are also allowed despite the health risks they pose when consumed excessively.
So, that argument doesn't hold much weight for me.

3) I'm not interested in responses that claim "there's no evidence," etc. There are plenty of studies demonstrating the risks to human health.

4) With this post, I'm simply looking for ideas on how to reduce EMF exposure.

Thanks!

** The unit is "mG" (milligauss), and the range is between 0 and 100. What TriField (the brand of the device I'm using) says is that, to be safe (when sitting on it for hours), it should be less than 5mG. I use the "MAG" reading, not "ELEC".

Could you take some foil from your hat and put it under the floor mats?

@ineedadrink Electromagnetic field is such a broad term as to be utterly meaningless unless qualified by units of some kind and the frequency of the field in question. Visible light is an electromagnetic field, so is the heat given off by a room heater and the radio waves that carry television and mobile phone signals. And so is the magnetic field of the closure that holds a mobile phone cover or a handbag closed.

The only hint we are given as to what he measured is the statement that he measured between 30 and 80 mG. I suppose that the meter uses mG to make the numbers look bigger because if you convert it to the international standard for magnetic flux density you get 8 uT (eight micro-Tesla). The Earth's magnetic field is about 50 uT.

The field inside an MRI scanner is typically about 1.5 T, nearly two hundred thousand time higher than the flux density measure in the car. Where does the idea that <5 mG is an acceptable level an, presumably, that higher levels are not come from?

Try Mu-metal. Used it as a shield for testing proximity sensors years ago.

@IHateViolence Actually Amazon sells a small sheet.

It's expensive as you can see. I'm sure certain metal suppliers carry it. Our metal shop bought it in sheets. Can't even imagine the price. That was in the mid 70s and they formed into almost egg shape cans of various sizes that could be stacked tops and bottoms forming multiple layers which the sensors were placed inside shielding them from the outside world.

@Gibbon Thanks! But yeah, seems too expensive for me to order, to try to test it on the car. And likely I'd need a lot of it, to cover everywhere. Seems impracticable. :(
Gibbon · 70-79, M
@IHateViolence Yeah I figured that. But it's designed specifically for that which is why the expense.

More proof that nothing is ever simple.
@ineedadrink Read what @ninalanyon posted - milli-gauss are a measure of magnetic field. See what they posted about your day to day exposure to the Earth's magnetic field.

That's a bummer..
