EMF exposure? loss of appetite after stroke

[Ellen Madono]

Are these kinds of frequencies easy to measure accurately? I don't know much about them, but the go through the walls. Not like light, heat ... More like xrays. I am not sure. I see many prices for these things.

[Shannon Nelson]

Hm, well, I think yes, they are easy to measure accurately. With both “easy” and “accurate” taken with caveats… ??????

There are many different prices (and many different meters) for many different reasons…

Ellen, you might find it interesting to look at: https://www.electricsense.com/

— and there are other similar sites; this is just the one whose name I happen to remember.
His link (below), “Which is the best EMF meter? My review” might perhaps be useful reading for you; he has lots of information about the issues, as well as about various meters — and I see tons of other links that I wish I had the time to read!!!

I’ve used a couple of TriField meters fairly extensively (mostly years ago), and found the information it gave me VERY interesting, and some of it very straightforward, i.e. locating an extremely strong magnetic field (NOT a good thing to sleep in!) right beside my toddler’s bed. To actually fix it would have been straightforward: have an electrician open up the wall, and wrap the wires appropriately, as (I am told) is today required by code. But the easier and “good-enough” fix we used instead, was simply moving her bed to another wall, where the field was quite acceptably low.

I think that link above will also include information about magnetic fields — magnetic fields, electric fields, and EMFs of various wavelengths: all of it really does matter, some more deeply than others.

Have a look!

What do you mean wrap the house wiring as per code?

I have never run into this in over 40 yrs of construction work. If you mean the cable covering; ie, romex or metal bx

then yes, tape wrapped black wire that you find in houses, say from the 1920's or earlier--that is illegal and has

been for many decades. The real concern had to do with rodent damage which could cause a house fire. EMFs

were not even in the vernacular when romex came into existence in my experience.

Hi Tanya,

I’m no electrician, but here’s what I’ve been told (below):
This part I do remember from long-ago science classes, that (a) a moving electric field gives rise to a surrounding magnetic field—and vice versa; and (b) when you wrap two moving electric fields (e.g. two current carrying wires) around each other — sort of loosely twisted, if I’m visualizing it right? — then their magnetic fields cancel each other out. Does that sound correct?

Hi, I am a retired electrician, we twisted coaxial cable to limit the electromagnetic fields. When installing signal advance “loops” in the street, we overlaid 3 layers and took care to NOT let them wrap around each other, a large magnetic field is needed to trip the signal when metal (vehicles) ran over them. I can’t see Romex being twisted, it is sheathed and usually only one run to an area, except by the panel. In Industrial building, we use metal conduits to pull wire, there is no way to twist those wires. I am retired, and have not heard of any new code requiring wires to be twisted in the USA. I just don’t see how it can be done, I have 30 years experience in electrical installation.

How do you know if the meter works?! How do you know if a radio works?!

Its simple technology at basis. The only question is, how accurate the meter is which determines its cost.

And you have to measure three things: magnetic energy, electronic field strength and microwave field strength. Thus you can buy so-called Trifield Meters. The last two fields are the same but cover different frequency ranges. But now there is 5G which is another electromagnetic frequency range altogether.
The only thing that will stop EMF radiation is a Faraday cage or equivalent. People are doing things like applying paint and window treatments that will ground the radiation, all of which are somewhat expensive. Also the ulility power Electronic meters can be shielded with metal screening; but they are a fire and privacy hazard also.
No device can protect you completely from EMF radiation but some claim to transmute it so it isnt harmful (questionalble). Others claim that they boost the earth's natural frequencies so that our bodies will tune to those so that we are less affected (or not affected?) by the un-natural man-made frequencies.

Thank you both! This is interesting. I never questioned what I (thought I) was told, because it seemed to make sense. This was about 30 years ago, and I assume just with reference to houses.
Just to check that I'm understanding you both: So if you were wiring up a new house, putting in sets of wires running to several different endpoints, you would simply run them in parallel?
Then in your experiences, is the issue of magnetic fields just not recognized or addressed at all in building codes?

I did a quick google, and this link seems to address some of the issues--I'll read it better in a while. It references "electrical fields", not sure if that's referring to the same thing I was calling "magnetic fields" (and yes I know they aren't the same!).

https://healthybuildingscience.com/2013 ... ring-best/

It refers to houses built more than 50 years ago -- and my information is from 30 years ago, so maybe that's the issue.
However, in my current, very crappily-built condo, there are INSANELY high magnetic fields in some awkward places such as under and around the kitchen table / overflow "office" space. I'm told that might be due to errors in grounding wires onto pipes. Does that make sense?

I wear a Q link bracelet constantly and hope for the best.
I did however have the results recently of a hair analysis test that said my body wasn’t stressed by any Toxins (chemical and hydrocarbons, Radiation or Toxic metals) so maybe it does protect as I have wifi running in my house day and night!!. (I am apparently stressed by Parasites though and a load of foods!!)

Hi Shannon, The link is accurate. I have only run into Knob and tube wiring once. I did a short 1 year apprenticeship on residential construction and the rest of my time was in commercial and research and development buildings. The only time magnetic fields and electrical fields were a real concern and had to be addressed were in top secret buildings with a lot of computer components that were highly sensitive. We had special insulated cable, and the conduits had to be installed so no one could “listen” in on anything. Other than that the industry does not seem to be concerned with any energy fields.

All circuits are required to be grounded, if in higher voltage (277volt) they are not, you would be having ground fault problems, circuits tripping, lights dimming, and shocks. In 120 volt circuits there is a risk of electrocution. Some older homes are not grounded.

To ground a pipe? Hmm I was thinking conduit, and that is automatically grounded by grounding the panel. In homes the ground goes to the copper water pipe, so is the question is the home properly grounded? That is the only pipe I can think of, and if the electrical system is not properly grounded I don’t know if there is an increase in Electrical fields and or electromagnetic fields.

In a new house construction, yes, we run the cable in parallel from the panel, and then branch off to get to the devices in the given circuit.

I hope I explained well. :-0
